    A. Intro
    Released on the GBA's launch day on 2001, Iridion 3D is a flawed but 
    nonetheless good shooter featuring beautiful 3-D graphics. It's a little
    sad how underrated the game is and I hope my FAQ would help some gamers who
    found the game a little too hard enjoy the most out of it. 
    I haven't done any shooter FAQs before, and this is my first under this name,
    so do give me advice on improving it through my email which can be found 
    above. Also pls notify me on my errors if there are any as well as additional 
    info I do not have in the FAQ. Well, that's all for me so enjoy the game!
    *Flawed ASCII text art, so do pardon it.
    **Contact me if this FAQ is found on the net altered (eg. with ads on it). I
    would really appreciate it.
    P.S. I don't have any names for the enemies (except bosses) of the games, so
    do inform me if you know of them. They would be greatly appreciated and you 
    would be duly credited.
    P.P.S. Always remember, this is only a guide, so the tips and strategies given

    B. Versions
    Version 1.0 (11/01/2003) - First version, completed FAQ
    Probably final version, but might update it one last time if I find extra 
    information/errors to add &/or correct. 
    C. General Tips
    i. Shot Power-ups
    There are a total of 5 different shot power-ups in the game. Getting a 
    power-up of the same kind increases the 'level' of the shot, making it more 
    rapid and powerful. Dying would decrease your shot 'level' by one, and taking
    a new kind of shot would reset everything to 'level' one. 
    The five power-ups are as follows :-
    Red (Personal Rating: 6/10)
    Availability: Stages 1-6
    This is the most basic shot in the game. You start off the game with this 
    shot, and there is nothing special about it, giving off (at it's first 
    'level') a single stream of bullets. Effective in the first two stages, the
    usefulness of this power-up is limited in the later parts of the game.
    Green (Personal Rating: 5/10)
    Availability: Stages 1, 2, 4-6
    Like the red power-up, this is a very basic shot type. Instead of a regular
    stream of bullets, the green shot has a scatter effect which is great when
    dealing with regular enemies. However, like the red power-up, it's efficiency
    is limited in the later stages and its usefulness falls in comparison to the 
    red one because you do not start off with it (which puts it always one 'level'
    lower than getting the red one) and it is not as effective against bosses 
    because of the scatter effect.
    Pink (Personal Rating: 3/10)
    Availability: Stages 2, 4 & 5 
    The pink shot power-up is more powerful than both the green and red ones, but
    I do not like it personally. First, it is only available on the second stage,
    which makes the highest possible 'level' of the power-up low. Also, the shot
    seems to direct itself to the center regardless of where the shot is taken. 
    While this is useful at some areas, this seriously hampers your aim, so if my
    word is to be trusted, stay away from this power-up.
    Gold (Personal Rating: 8/10)
    Availability: Stage 3
    The gold shot, while only available in stage 3 with a maximum of 3 'levels',
    is the shot which would be used most frequently (namely from stage 3 until the
    last). Barring the blue shot power-up, this is the most powerful shot 
    available in the game and 'level' one of it is easily more powerful than high
    'levels' of the other three power-ups mentioned so far. Also, keeping the gold 
    shot would be crucial in making a quick and efficient battle out of boss #6, 
    saving a lot of valuable life which would otherwise be gone because of the 
    hectic battle.
    Blue (Personal Rating: 10/10)
    Availability: Stage 7
    The most powerful shot in the entire game, the blue shot is not only packs a
    punch but is also big in volume making it easier for your aiming. Although 
    only found in the last stage, there is a fair number of power-ups scattered 
    around so you should get a relatively high 'level' when you reach the final
    boss (that is if you survive so far, which wouldn't be easy and would require
    lots of practice and to a certain extent, luck). You can basically forget 
    about completing the game if you, for some reason, skipped the blue shot 
    power-up thoroughly in the last stage.
    ii. General Tips & information
    Basic Information :-
    --> Every life consists of 12 health units
    --> A collision takes 4 health units; a bullet 1
    --> There is an extra life when your score reaches 10000, 20000 and 40000
    (There might be more but I did not go so far in the game, my highest score 
    being only 150000+ for now)
    --> After every stage, you would be awarded points based on the health (50 for
    each unit) and lives (1000 for each) you have left
    General Tips :-
    1) Life is the most valuable asset in the game. It is safer to avoid a nearby
    enemy rather than risk defeating it. All you get for doing the latter 
    successfully is a few points and failure means around a third of your life 
    gone. Health recharges are hard to come by in the game, so it's always better
    to play safe. Keeping your life also means you keep your shot 'level' which 
    would be very helpful in defeating enemies.
    2) Stick with specific power-ups. Changing a power-up means starting all over
    from 'level' one of the shot again, so choose your fave and stick with it. 
    Personally I prefer the red one for the first two stages, the gold one for the
    next few before the blue one in the final stage.
    3) Last, and probably the most important point in succeeding in Iridion is 
    practice. Nothing would work without it. With practice, you would improve in
    your ability to move around the screen, aiming (which would originally be 
    daunting because of the 3D perspective) and also familiarising yourself with
    the stages and bosses. The game is actually very short, but it is this trying
    over and over again which makes the meat of the game.
    D. Stage + Boss FAQ 
    Stage 01 - Escape Through the Disposal Tunnel
    While some may find this stage a little tough as a starting mission, it is
    actually rather simple as the key of succeeding in the stage is getting the
    hang of the 3-D perspective and knowing where to position yourself to shoot
    enemies. You would get the hang of it soon enough, so stick with it and as
    with other stages (and mentioned in the general tips section), it is always
    wiser to avoid enemies close-by rather than going in for the kill so as to
    save prescious life.
    Starting off the stage would be wave after wave of enemies that look something
    like machine parts. They do not have any form of attack so just kill whatever
    you can when they are at a distance before avoiding the remaining ones. Slowly
    the waves would have more enemies and come more rapidly but shouldn't be 
    anything too hard to get through.
    After the waves would be a button-shaped, starfish-like enemy. When it gets
    close to you, it would shoot out a stream of bullets which would be rather
    difficult to avoid, so brush up your aiming with some practice and kill it
    before it gets a chance to shoot the bullets. 
    There are two of these enemies for now, and you would probably have to defeat
    them to advance (though if you wait long enough you can avoid killing them 
    completely), so make light work of them and proceed on.
    A little distance off the second enemy, you can see your first shot power-ups,
    a red and a green. Make your decision between either one (i prefer leveling up
    the red one to changing to the green shot; see 'SHOT POWER-UPS' section for
    more info) and grab it. 
    Next up would be some plane-like enemies. They shoot bullets when they close
    in on you, so avoid them (takes some practice, as so often the case) while
    shooting at the enemies. Slowly, more and more planes would appear more and
    more rapidly, so you would most probably have to avoid the planes, which would
    make turns towards the centre when almost at the screen along with the 
    Received quite some damage (hopefully no lives are lost yet)? The health
    power-up is next after the last of the planes get pass. Looking exactly like
    a shot power-up, the health power-up is distinguishable by the flashing colors
    of it. Taking it not only heals your life back to max but also earns you some 
    points, so there is no reason to miss it since they're no enemies around.
    Just after the health restore, the next enemy is a sensor-like one located on
    the four sides of the tunnel. Failure to defeat all four of them would result
    in an explosion when you pass them, taking your entire life (something which
    kinda make me wonder about why the developers put it there, making it 
    'unwelcoming' for new players to the game). Hence, develop your own routine of
    eliminating these sensors quickly and effectively (practice... now how many 
    times have I said that?) to avoid a wasted life.
    The difficulty of the next area would depend on what you have set out to do.
    If avoiding enemies and hence, damage is your objective, then it is a breeze,
    but if your aim is to kill as many enemies as possible, it would be quite 
    The enemy here is fan-like with the 'weak-point' at the centre. Not only is it 
    hard to aim perfectly at the right spot, the time the game allows you to 
    execute the kill gives little room for error, so avoid whenever you cannot 
    seal the kill. There's no penalty for avoiding other than not gaining some 
    meagre points (which is rather useless after the 40,000 mark, easily 
    attainable when you can breeze into the 3rd/4th level), so do not take the
    risk as there are no more health power-ups before the boss fight.
    At the end of the fans is a big one spanning almost the entire tunnel. It 
    might be possible, but personally I have yet to find a way to defeat it, so my
    only advice is to avoid (my second favourite word after 'practice'?). There 
    are different ways to get around it without receiving damage, but one way 
    which has worked for me is to stay at the bottom of the screen before moving
    left when into the areas between the blades of it.
    After that, you'd get another wave of the 'machine-parts', the first enemies
    of the stage. There's only two short waves, so there's not much difficulty 
    here. Moving along, the next enemies would again be a familiar one, the 
    'button-starfish' like enemy. This time there'd be three, and like the earlier
    part you would probably have to defeat them to advance given the long time 
    they take to go past you.
    Next up would be a some shot power-ups (once again red and green) again 
    followed by the sensor enemies, so just follow what you did to eliminate the
    first 'quartet'. Regarding the shot power-ups, I advice you to get the same
    shot type that you currently have so as to increase the level of the shot
    which would be useful for the upcoming boss fight.
    The last enemies of the level would be the planes you encountered earlier,
    in exactly the same formation as they did when they appeared the last time,
    so getting through it shouldn't be a problem if you'd not encountered much 
    the first time round. After they are reduced to dust or have gone past you, 
    your plane would fly into the distance, ready for the first boss fight.
    Difficulty rating: 3/10
    Possibly the simplest boss in the game, you should easily defeat this boss
    without suffering any damage once you'd mastered the trick against him. 
    This boss consists of a central 'pillar', the boss's weak spot (read: the only
    spot which take suffer damage) and four bombs constantly moving around it in
    a circular, clock-wise manner. Basically the boss has modes of action only, 
    the first has it doing nothing (the bombs present the only threat) while the
    next involve it shooting some bullets at you with the 'pillar' closed, meaning
    it takes no damage from you.
    During the first 'mode', go to the center of the screen and hit him with 
    bullets (as if you didn't know that, ;P). However, the bombs would almost
    always go through that point in their route, so go up/down, whatever feels 
    smoother for you to let them pass before going back again.
    Soon enough, the pillar would close up. Here, prepare yourselves for its 
    bullets. There are many ways around it, but one which has worked for me 
    involves moving to the south-eastern corner of the screen when the pillar
    starts closing and when a bomb had passed that area, move in a large,
    anit-clockwise circle around the perimeter of the screen. This, if done right,
    would evade all the bullets + the bombs. 
    After that, the pillar would open up again, so go through the previous two 
    steps until you defeat it (along the way, the pillar would crack as it 
    receives damage, in the end changing into something which looks like a dna
    thread just before it's defeated). How fast this battle would take would 
    depend on the level of the shot power-up you've managed to keep earlier.
    STAGE 02 - Dogfight Above the Pacific Ocean
    Immediately into the stage, you'd be faced with wave after wave of enemies 
    (now how do I describe them?). They move quite fast towards you, but have no
    form of attack, so just mow down each wave from far before avoiding them when
    they're near.  
    After the waves they'd be two continuous rows of planes advancing towards you,
    one after another. Again, they have no attack, so just pick up whatever you 
    can and proceed on. 
    Three shot power-ups (refer to 'shot power-up section) would be available at 
    the end of the planes, so take whatever you feel is suitable and continue. 
    After the power-ups, they would be more planes of the same kind, only this
    time they're coming from behind, so as usual, just handle what you can.
    Further on, they are bombs (placed in a 3-by-3 fashion) on the sea below, so
    avoid them as they would splash water vertically up when you approach them.
    It may seem like you'd just received your last shot-power up, but looks like
    there's another selection in the middle of the bombs for you to get. 
    After the power-ups come your next enemy. They consist of 8 of those diamond
    shaped enemies you first encountered earlier on in the stage arranged in a
    circular manner with one colored blue. It would move in a circular manner,
    rotating, with the weak-spot on the blue one. When it starts moving in a 
    circle, follow the blue enemy anti-clockwise and shoot at it. You can't get
    shots when it is at some places, but you can damage it a lot when it is nearly
    at the end of a 'cycle' and is at the south-west part of your screen.
    Shortly after that the 8 units would all move in to form a ring. Here, they 
    would shoot bullets and cannot be damaged. To avoid the bullets, my trick is
    to move to the west side of the screen, moving up and down between the bullets
    to avoid them. Soon, the enemy would move towards you, making the bullets 
    difficult to avoid. Prevent this by moving to the bottom of the screen and 
    this time move left and right to go between the bullets. When it starts 
    going back to the center of the screen, move back to the left side of the
    screen. The same cycle would happen again, so rinse and repeat to advance.
    After that, planes would start appearing from far. This time, however, they
    shoot bullets so make light work of them while avoiding the bullets. 
    The transaction to the next enemy would take place rather swiftly. Even before
    the last plane passes you, you would see the bombs on the sea again. Even with 
    the enemies, they are rather easy to avoid. Immediately up would be waves of 
    the diamond-shaped enemies you encountered at the start of the stage. As with
    the earlier section, pick up all you can from far while moving to avoid the 
    They're the last set of enemies, so prepare for another boss.
    Difficulty rating: 4/10
    While not exactly tough, the Cytector can dish out significant damage if you
    do not know how to avoid its attack. It has basically three 'modes'. 
    The first one has it staying in the center with bombs released on either side
    of the screen. It would take considerable effort just to ACTUALLY get hit, so
    attack all you can (in case you haven't figured out, the 'weak spot' is the 
    rotating thing on top of it), following it's sway.
    After some time, it'd switch to the second 'mode'. This one has it flying up
    into the air and shooting some bullets from the bottom of it. While you cannot
    deal any damage to it at this mode, the bullets are rather easy to avoid (just
    stay in the bottom-left corner of the screen), so just wait patiently awaiting
    the next 'mode'.
    Finally, it would move back down the screen. Here, in addition to the bullets
    at the bottom which are still being shot, a turret would appear on the top and
    shoot at you. You can shoot at the Cytector again, but it would take quite 
    some practice to avoid all the bullets. My trick is to stay at a place for 
    some time, causing the bullets to come at you in a straight line and make 
    sudden movements left/right (not going down because of the bullets there) 
    which would leave a gap in between the two streams allowing you to move there,
    avoiding the bullets.
    Again, the three modes would continue in a cycle, so repeat everything again
    to defeat it.
    The third stage, the only containing the powerful gold shot power-up, is 
    critical for progress through the rest of the game. Having a gold shot power-
    up until the last stage would make your game much, much easier, so be sure to
    get the three available power-ups available in the stage. 
    Right into the stage, you'd be able to get your first two gold shot power-ups,
    so grab them without fail. From here you'd meet your first enemies of the 
    stage, planes which shoot homing missiles. The missiles would home in (duh!)
    on you so just move around the screen constantly to avoid them. Also, the 
    planes are also rather powerful, so unless you've gotten the two gold shot 
    power-ups, it is going to be quite tough to kill them.
    After the planes would be some saucer-like enemies, moving around the screen,
    leaving a steady stream of bullets behind in their path. During this part of 
    the game, you would probably experience some slowdown, which would actually 
    help you in avoiding the bullets left behind. Killing the enemies would mean 
    less bullets for you to avoid, so try to kill off as many of them before 
    heading into the corners of the screen where there are no bullets to avoid
    While the long wave of enemies is about to come to an end, there would be two
    power-ups available to you, a red and a gold one. Of course, avoid the red one
    completely and grab the gold power-up. 
    After the last of the saucers, another type of enemy would appear. This time,
    it is the diamond-shaped enemies you encountered in the last stage again, only
    that they are bounded in threes now, making them a little tougher to avoid.
    However, you should probably have no problem in killing them with your 
    powered-up shot and avoiding the rest.
    Also at the start of the enemies is a health restore. Just be careful not to
    collide with the enemies in your attempt to get it.
    Next up after is another round of those planes with the homing missiles. 
    Thankfully, there are only four of them now so you might even dispatch all of
    them without allowing them to shoot a single missile provided you have a high-
    enough shot power-up.
    Two saucers are up next, but they should pose no problem at all as the low no.
    of them means you can get rid of them quite easily. After that, another four
    planes come up again, so it's just a matter of not making silly mistakes.
    The next, and last wave of the stage is slightly more interesting. It is a
    combination of the saucers and another type of planes (those which have no
    attack at all). This time, you'd have to divide your attention between the
    two types of enemies, making it tougher to avoid the bullets. The trick is to
    kill the saucers first (just be sure not to hit the planes) before attempting
    to hit the planes, which require less bullets to kill.
    After the last of the enemies get past you, it's time for another boss stage.
    Difficulty rating: 6/10
    There are two stages to this boss. The first involve it shooting periodic 
    streams of bullets at you. This is very easy to avoid by just moving round the
    screen. While you'd not get as much hits as you would if you stay in the 
    center, you'd still get enough damage on the boss soon enough, where its 
    outer armor would break, changing its attack to the second stage.
    The next stage of its attack involves the boss shooting out bullets from its
    six turrets around it. This is very hard to avoid. The best way I have found 
    to do so is to stay approximately at the boss's four corners. However, staying
    there would be tough because of its movements and even then, you'd probably 
    still get hit. 
    How you fare here would depend on which 'level' of your gold shot (it'd be 
    almost impossible to defeat this boss without losing a huge chunk of your
    lives if you don't have the gold shot for some reason) you have managed to
    keep after the level. Having a level two or three shot would make your fight
    relatively easier due to the less time spent in eliminating the boss and hence
    taking less damage.
    Unlike the previous stages, the next two stages you are going to encounter 
    will just feature repetitive waves of similar enemies at you constantly, so I 
    can't give much help on them except for some general tips.
    Moon Assault is the most expansive stage in the entire game, giving you lots 
    of space to manoeuvre about, so make use of this extra space to avoid the
    taking damage. Also, there would be numerous shot power-ups scattered around
    the stage. As I'd mentioned so many times in this FAQ, it is advised that you
    keep your gold shot power-up for now.
    There are only three enemies in this stage. The first are stick-like bombs
    lying in different 'formations' throughout the stage. They shouldn't pose any
    significant problem because all you have to do (and can do) is to avoid them
    although they do make avoiding the other enemies in the stage a little 
    tougher, so do keep an eye out on them just in case you hit them when fending
    off other enemies.
    The other two types of enemies in the stage are yet another kind of plane-like
    enemies. Both of them are look different (with one green while  the other 
    yellow), but their attack is very similar, involving shooting occasional 
    bullets at you and making sharp turns when approaching the screen. While the
    bullets are relatively easy to avoid, be careful not to be cornered by the 
    bombs when the planes are approaching so as to prevent getting hit.
    Anyway, this is a rather long stage so prepare to tackle loads of enemies 
    before finally reaching the boss (also, take note of a health restore in the
    middle of the stage at the end of some bombs arranged in a box-like manner).
    Difficulty rating: 5/10
    One of the more interesting boss in the game imo, this one is made up of a 
    central, main enemy surrounded by blue spheres moving round it constantly. 
    Your objective is to hit the enemy at the center as hitting the spheres would
    not do the boss any damage but instead have your bullet deflected back at you.
    While this can be a little tricky, the spheres would almost always leave a 
    'hole', which is pretty easy to spot, for you to shoot at the boss. The only
    problem is that they are constantly moving, meaning the 'hole' would move 
    about randomly too, so you have to react fast. Some hits would be inevitable,
    but they shouldn't pose too big a problem.
    Also, the boss would periodically shoot streams of bullets through a central 
    turret. You can risk taking damage by continuing shooting at it, but the wiser
    choice would be just to stay at one corner (the bullets are not hard to avoid 
    at all) and wait for it to stop before resuming your attack.
    If you still have your gold shot power-up (which you should), this boss 
    shouldn't take too long to defeat, and you can move on to the next stage.
    If you thought that the last stage was pretty repetitive and boring, wait till
    you see this stage!
    There are three types of enemies in the stage, and what makes this stage so
    dull is that all it does is to throw wave after wave of those three enemies at
    you with not much strategy involved.
    The first enemy is a rocket-like enemy that shoots out circles of bullets. The
    bullets are pretty easy to avoid, so it's not too big an obstacle. However, if
    killing is what you desire, it packs quite some health and unless you have at 
    least a level 2 gold shot power-up, it's gonna be quite tough defeating even
    one of these.
    The next enemy is a blue asteroid. They have no attack, but would 'home' in on
    you. However, they take only a bullet to kill, making them easy kills as 
    you can just shoot straight and they'd would move into the path of bullets, 
    killing themselves.
    The last type of enemy is just a normal asteroid. They float around the 
    screen, making very little movement. The trouble with them is that they take
    a fair amount of damage before they die, so you'd probably be left with many 
    of them in your screen throughout the level. This makes moving rather 
    difficult as you might hit into them. This, coupled with the other two types
    of enemies would be the main problem for you in the stage.
    As mentioned earlier, this stage would literally throw waves of enemies at 
    you. It is a relatively short stage, so there are no health restore in the
    stage, making health very precious. Hence, a good way to handle this stage is
    to stay in the bottom part of the screen, shooting at the blue asteroids while
    avoiding the rocket-like enemies with their bullets. Pay special attention so
    that you do not hit the normal asteroids and this mundane stage (imo) would be
    over soon.

    This is one of the simplest boss in the game, although rather boring as well.
    Anyway, like many other bosses encountered throughout the game, this boss has
    different attack modes (2 this time round) with the first mode invulnerable to
    all forms of attack.
    The first mode involves two caterpillar-like projections constantly shooting 
    bullets at you. This mode is very easy to get through as all you need is to 
    move around the screen in a smooth, circular (either anti or clockwise would
    do fine, though I find moving anti-clockwise to be simpler for me) path for 
    some time. Do it correctly and you can easily avoid all the bullets shot.
    The next mode is a bit more complicated. The prospector would 'open up', 
    revealing a flower-like structure underneath which would move from the left to
    the right. Your aim is to hit that thing.
    Also appearing would be four turrets lined up in the bottom part of the boss,
    and they would shoot bullets simultaneously for about three times. The problem
    here is that moving yourself here is rather challenging with the screen 
    seemingly moving, so getting hits on it while avoiding damage would take some
    However (fortunately), you'd most probably not suffer too much damage this way
    so just repeat through the prospector's two modes of attack to finally defeat 
    it. It is not so much skill but time which is needed to finish off this boss, 
    making it rather boring. Stick to it, though, and next stage would be very
    much different.
    Even though this is the shortest stage in the entire game, it is without any
    doubt the most challenging with lifes probably lost most in this stage.
    This stage's premise is pretty much like the first one where movement is 
    rather confined to a relatively small area. The first thing you'd meet 
    immediately into the level are two shot power-ups, the red and green one.
    However, as I'd mentioned so many times throughout the FAQ, avoid them unless
    you want a heck of a battle for the next boss.
    After the power-ups would be your first enemies of the stage. There are a 
    total of four of them, each consisting of eight separate enemies bounded into
    an octagon (duh!) shape. They would constantly 'expand' and 'contract', with
    one of them shooting out a stream of bullets. Due to the hard to predict 
    movement of each one, avoiding collision would be rather tough as you have to 
    decide whether to move to the center in a probable 'hole' of take the corner
    if they're 'contracted'.
    The best way to avoid this is to kill as many of them before they approach 
    (don't care so much about the bullets, they don't deal as much damage). The 
    more you kill, the easier it'd be for you to avoid them as they come. In the
    middle of the wave of the four octagons would be another set of shot 
    power-ups. Do be careful not to get them in the midst of trying to avoid the
    Next up would be a snake-like enemy. Its head would constantly shoot bullets 
    and the only vulnerable part of it is its red-colored tail. Due to the 
    'snake's' movement, it would be rather difficult to hit it. The only tip I can
    offer is to move in anti-clockwise circles following its movements (it would 
    get you hits as well as avoiding the bullets) while escaping to one corner
    when it's near so as to avoid damage. You'd probably have to defeat it to 
    advance, but if you can wait long enough, it would eventually move past.
    The next wave would be a barrage of bullet-shooting bombs coming at you fast.
    Avoiding collision would be your main aim (trying to avoid the bullets as well
    would be too risky) so move around the screen fast and keep your eyes out on 
    the incoming enemies.
    Immediately following this wave would be another round of enemies. This time,
    they consist of bar-like bombs moving straight at you. They would come out 
    aiming at where you are though they cannot make any more movements except head
    straight once you see them. Moving wrongly would easily trap you in a corner,
    so my trick is to move in sudden spurts so that there would be spaces in
    between the bombs when they come for you to 'hide' in.
    The next set of enemies would be another wave of 'octagons', with a shot 
    power-up in the middle of it followed straight by those bullet-shooting bombs,
    which following the same strategies provided above would do.
    The last enemies of the stage would be a return of the 'snakes', only this 
    time they're shorter and you have three to handle. This would make the fight
    rather lengthy (and as with the previous 'snake', you can wait long enough to
    have them past you without killing them). There's not much strategy I can 
    provide other than the one I gave for the last battle where you move in 
    circles following one of them and moving to a side when they come close.

    I've played this boss countless times, but I've yet to find an effective
    strategy in defeating it. The most efficient I find is to just pummel it with
    shots not caring about damage to yourself and hoping that the battle ends fast
    enough before you lose too much health (that is why a gold shot is so 
    essential in defeating this boss using my method).
    The boss involves a central core that takes damage with numerous things at the
    side shooting bullets at you in no particular manner. Do be creative when 
    dealing with this boss and provide me with a better and efficient method to
    overcome it. I would be really thankful for that.
    Congratulations if you have made it thus far, it's not easy getting to the
    final stage even though this is a really short game. And to round it up, this
    is imo the most enjoyable stage in the entire game so have fun before the 
    final boss fight which would definitely cause lots of problems.
    Immediately into the stage, you'd see some little flames on larva sea (or
    whatever it is). They act like those bombs you saw previously on the sea in
    stage 2, exploding when you're approaching it, so avoid them (which isn't too
    After that, you'd encounter two obstacles. The first is some flaming asteroids
    raining down from the sky. While they cannot hit you, they would cause a tiny
    flame upon hitting the 'sea', which would cause damage if you're near it. 
    Meanwhile, the other enemies you'd encounter are the planes with the homing
    missiles from before. Use the same tactic (moving constantly in circles to 
    avoid the missiles) as before to get past/kill them, though this time do be
    careful not to venture too much south because of the flames the asteroids 
    After the wave, your next enemy are fire dragons. They appear from the 'sea'
    and would make an arc before going back in. As far as I know, you cannot 
    damage it so just avoid them (shouldn't be too difficult because of the 
    numerous holes they leave for you).
    Between the wave of dragons would also be two blue shot power-ups, the most
    powerful shot in the game with the biggest damage and a large area. Be sure to
    grab them!
    Next up would be a repeat of the previous wave consisting of the flaming 
    asteroids and homing-missile shooting planes. This would be a much longer one,
    though you should handle them without much casualty. Also be on the lookout
    for another blue shot power-up in the midst of the wave.
    The next wave is a little more challenging. Throughout this wave are some 
    button-shaped enemies grouped in fours shooting bullets. This, coupled with
    the flaming dragons for the first part of the wave and the flaming asteroids
    for the second part might be rather tough to handle. The best way is to just
    jam on the attack button, getting a fair share of kills off the button-shaped
    enemies because of the power and size of the charged-up blue shot while moving
    around avoiding the dragons/asteroids.
    Also in the middle of the wave is yet another blue shot power-up.
    After that would be the next combination involving the flaming dragons and
    asteroids, with a health and blue shot power-up to be found. You'd gone so
    far so avoiding them would certainly not be a problem.
    The next part of the stage would be simple 'mix n match' of the aforementioned
    enemies which you can get through using the same strategies provided above. 
    Do be on the lookout for yet another health and blue shot power-up in the 
    meantime too. 
    The only problem you'd probably encounter in this part would be a return of 
    the button-shaped enemies. This time, they are grouped in eight and move in
    a very special pattern. This movement makes their bullets come really fast at
    you and very tough to avoid. The trick is to just clear as many of them as you
    can from far so that they don't have many of the enemies left to shoot at you,
    making your job much, much simpler.
    Difficulty Rating: 10/10
    You would probably have played the game for quite some time now just to get
    to this part of the game, but be prepared to spend more time on it though this
    is already the final boss. Not only is this boss tough and require quite some
    skill to defeat, you'd also need a healthy supply of lives left (I needed 5 
    lives to defeat it for the first time, and the least I've managed so far is 
    1.5, and that is after lots of retries and practice), so be prepared for a
    tough time.
    There are three 'stages' to this battle. The first is undoubtedly the 
    simplest, with the boss shooting bullets and the periodic flames. The flames
    do damage equivelant of a collision, so avoid them by moving in a large,
    anti-clockwise motion (try not to cut corners as chances of getting hit is
    higher). The bullets would still hit you, but the damage taken would be much
    Also, throughout the fight, note that the boss can be hit no matter where you 
    are on the screen, so just jam on the attack button and just care about 
    moving. If you have did everything correctly and have a high enough shot 
    level, you should get through this part of the boss without losing a life, 
    after which the boss would move back and come at you again.
    The next stage of the Main Frame is much tougher. MUCH, MUCH TOUGHER. This
    time, it would use a fire whip to attack. This is very difficult to avoid due
    to the movements of it. The whip would at take small movements (which 
    shouldn't pose a problem) before stabilizing at a postion. At this point,
    position yourself directly opposite of the whip.
    After that, it wing rapidly down, first in a direction (either anti/clockwise)
    before turning back halfway through. The way to avoid it is to first move 
    along the direction it is turning, before turning back after a semi-circle.
    However, this is easier said than done. It takes lots of practice to perfect
    turning back at the exact moment to avoid the whip. Just be prepared to lose a 
    few lives here and pummel it with shots to finally defeat it.
    Finally, the last part of the battle. If you'd made it through with around two
    lives left, then chances are you're safe. This time, while the boss would use 
    two fire whips, it isn't as tough as the previous part as the movements of the
    whips are significantly slower this time round.
    However, the only problem with this part is the unpredictable movements of the
    whip. Generally, the whip would just move in a direction so moving along in 
    the gap between the two whips would do fine. At random moments, the whips 
    might slow down or suddenly turn in the other direction, so you have to be 
    really alert. The key to this part is observing the whips closely and 
    anticipate its move, after which avoiding damage wouldn't be too hard.
    It might take some retries, but soon you'd finally defeat the boss and hence,
    complete the game. Give yourself a pat on the back for your hard work. 
    Now just sit back and watch the credits roll, after which you'd get the 
    password for the gallery (*G4LL3RY*) containing some of the concept art.
    If you're still hankering for more Iridion (and don't want to fork out extra
    money for the sequel), the hard mode is the only thing left to do. However,
    the only difference for this mode is that taking one bullet hit would be
    be the equilivent of one collion (in simpler terms, the damage for everything
    is pumped up). I personally haven't completed this mode yet, so if you're 
    hardcore enough to spend more time on this game and actually complete it, do
    mail in and tell me if it unlocks anything new. So till then, that's all in
    the game!
