    1. Intro
    Super E.D.F. is a side scrolling shoot 'em up released in 1992 by Jaleco for 
    the arcade and later the SNES platform. It's a little different from other 
    shooters of the day as it lets you customize your firepower a bit more and 
    also allowed you to directly control your satellite ships, which adds more of 
    a tactical element to the game. Also, you can survive getting hit more than 
    once before dying, which was completely unheard of at the time. All in all 
    it's a little shorter and a little easier than the more well-known shooters 
    but it's entertaining nonetheless. This guide will cover all the gameplay 
    elements, including weapons. A step-by-step walkthrough is little excessive 
    for this kind of game but you'll find helpful tips for getting through the 
    tougher parts of the game as well as for beating the bosses. Good luck!
    2. Controls
    The controls for the game can be customized in the options menu with six 
    different configurations. I will cover the default configuration.
    D-pad- Movement
    X- Adjust speed
    A- Change satellite formation
    B- Fire
    Y- Nothing
    L- Nothing
    R- Nothing
    Select- Nothing
    Start- Pause
    3. Basics
    E.D.F. is a little different than the average SNES shooter. Pay attention to 
    the basics of the game and you'll beat it without breaking a sweat.
    SHIP SPEED - Press the X button to adjust your movement speed. The arrows at 
    the top of the screen indicate the speed setting you're on. I recommend 
    staying at level 3 for the whole game. The other two settings don't allow you 
    enough speed to dodge the trickier shots in the game, and the highest speed 
    setting isn't all that fast anyway.
    SHIELDS - Unlike a lot of other shooters, you won't die from taking a hit. 
    Instead, you have three shields, indicated by the green markers at the top of 
    the screen. You lose one each time you take a hit, and once the last one is 
    gone, it's game over. You get a few seconds of invulnerability after getting 
    hit (your ship catches fire during this time), so use that time wisely to get 
    to a safer location on the screen. Your starting shields can be changed in 
    the options menu; if your current shields are below this number, they are 
    refilled when you start the next level. You have 3 continues in this game; 
    each time you die you can change your weapon. 
    LEVEL - Another neat aspect is the level up system. Blowing up enemy ships 
    increases your experience bar, and once it gets full, you will level up. 
    Increasing your level will also increase the strength of your weapons and 
    allow you to use different satellite formations. Note that your level does 
    drop when you die, so even if you have to use a continue, you can keep your 
    level. You also get a huge "secret bonus" if you complete a stage without 
    getting hit which contributes a lot to your next level up. The maximum level 
    is 5; any more level-ups after that will grant you extra shields.
    SATELLITES - Your ship comes equipped with two smaller ships called 
    satellites. These satellites provide extra firepower and protection for you. 
    The satellites are indestructible, so they can absorb enemy gunfire and even 
    damage or destroy enemy ships if they touch them. Your satellites behavior is 
    determined by the formation you're using; press A to cycle through different 
    formations. Remember that some of them require a certain experience level 
    before you can use them.
    Union: The satellites are united with you, docked just under the nose of your 
    ship. This ensures that your weapon is at maximum power but it doesn't do 
    much else. The satellites can still block enemy fire coming from beneath your 
    ship, but that's about all they can do. I don't recommend using this 
    formation at all, unless you have the Photon weapon.
    Rotation: The satellites rotate around your ship. This gives you the most 
    protection from enemy fire while still maintaining your level of firepower. 
    Note that your ship will also fire its own blaster while your satellites use 
    your selected weapon.
    Shadow: Unlocked at level 3, the shadow formation causes the satellites to 
    mimic your movements. They play "follow the leader" essentially, perfectly 
    following your every movement. You can use this formation to get your 
    satellites into certain positions on the screen so you can attack without 
    having to expose yourself. The boss of stage 2 is particularly vulnerable to 
    this tactic.
    Homing: Your satellites pair up and seek out enemies, staying on them until 
    they die. This formation basically adds a homing capability to any weapon, so 
    it's extremely useful because it allows you to make use of the powerful 
    weapons such as Atomic and Explode. The only downside is that the satellites 
    are away from your ship the whole time, leaving you exposed. When using this 
    formation, you just need to hold down the fire button and then focus on 
    dodging enemy fire while your satellites do all the work. Unlocked at level 
    4. Weapons
    You pick which weapon you want at the beginning of every stage or after using 
    a continue. The game ranks the weapons according to power, speed, and rapid 
    fire but these rankings are a little inconsistent and don't give the full 
    picture of the weapon's capability. Here are my recommendations:
    VULCAN: Fires a spray of bullets like a shotgun that spreads out in front of 
    your ship. This is a pretty basic weapon and has decent power as well as 
    speed. The only downside is that the weapon behaves quite differently if 
    you're using your satellites; they lose the spread effect and just shoot 
    forward. You may find yourself using the Union formation more often with this 
    weapon, but it works well in any other.
    LASER: A powerful weapon, the laser can only shoot straight ahead, but it 
    will decimate anything in your path easily. You'll find its power to be 
    especially devastating on level 4 or 5. Since it can only shoot forward and 
    has a low rate of fire, this weapon works best with the Homing formation.
    ATOMIC: This weapon fires canisters that explode into huge blue bubbles. Not 
    only is this weapon fairly powerful, but the bubbles will also erase enemy 
    gunfire. This is the best all-around weapon once you get the Homing formation 
    but before you reach level 5, you may want to stick with a different weapon.
    HOMING: Homing is a very cool weapon which fires very quickly like a machine 
    gun. Each shot homes in perfectly on the enemies, which makes this a very 
    easy to use weapon. Its biggest flaw, though, is that it's really weak and 
    can take forever to kill some enemies. For that reason, it's not a good idea 
    to use in the later levels because a lot of the enemies will fly off the 
    screen before you can kill them, causing you to miss out on experience. This 
    weapon works well in any formation except for Homing (obviously).
    EXPLODE: Fires big blasts of energy that explode when they hit enemies, 
    causing secondary energy blasts to hit other enemies. Explode is very 
    powerful, even more so than Atomic, but it can't erase enemy shots, either. 
    Since it only shoots forward, this is best used with the Homing formation.
    S. LASER: Technically it's a homing weapon, but what really happens is that 
    your satellites turn and aim at enemies. Whereas the Homing weapon will chase 
    down enemies, S. Laser can be dodged by faster enemies because the shots 
    travel slowly. However, the lasers will also pass through enemies, which 
    gives this weapon quite a bit of power. It works well in any formation.
    GRENADE: This is a weird one. It just shoots grenades forward a short 
    distance that explode. Grenade is extremely powerful but it's really short 
    range kills it. The grenades also don't explode when they hit enemies, only 
    when they travel the short distance. In short, the weapon is of dubious value 
    and I recommend you don't use it. If you absolutely have to, use the Homing 
    formation, otherwise you'll never hit anything.
    PHOTON: Allows you to charge up shots and then release them for big damage. 
    This is the strongest weapon in the game if you keep charging to full power 
    but that also means it has a very poor rate of fire. Aim carefully with this 
    one. Only use this weapon in Homing or Union. In fact, this weapon is the 
    only one where Union works well because it has a unique behavior; when you 
    charge up, the satellites come out in front of you and create an energy 
    barrier that absorbs enemy gunfire. You can hold this charge for as long as 
    you want until you're ready to fire it.
    a. Stage 1
    Recommended weapon: HOMING
    The first stage is fairly easy, especially with Homing. The enemies are weak 
    enough such that Homing can take them out pretty easily. The only problem 
    ships are the round ones that shoot lasers, as they take quite a bit more 
    punishment before they die and they have a tendency to appear behind you. 
    You'll likely hit level 2 during this stage, which makes dealing with them 
    The mid-boss is easy to beat. He just floats around the screen lazily, 
    letting you hit him for free. He will eventually shoot bullets in a circular 
    pattern; just dodge in between them and finish him off.
    The boss is a little harder, but not by much. Stay in between the guns on top 
    and bottom of the ship so that when they fire, you'll avoid getting hit. 
    After that, he'll open up and shoot a large fireball, followed by a second 
    one. After you've trashed him, he'll stop using the big guns and will start 
    firing a spread of bullets at you. It's tough to slip between them, so just 
    fly up or down and go around them. He'll shoot the fireballs as well, so keep 
    your eyes peeled. The secret bonus is pretty easy to get on this stage, so 
    try to get it so that level 3 will come up faster.
    b. Stage 2
    Recommended weapon: HOMING or S. LASER
    Either weapon is good for this stage. As long as you have something with 
    homing ability, you'll be fine, as a lot of enemies come from many different 
    sides. You'll probably hit level 3 at some point in this stage, which allows 
    you to use the Shadow formation. This makes it easier to deal with enemies 
    coming from behind you if you're not using a homing weapon. Other than that, 
    it's a fairly easy stage with no mid-boss, so hopefully you can get the 
    secret bonus.
    The boss is a joke. He just slowly flies up and down and fires shots out the 
    front. None of his attacks every go to the bottom of the screen, so you're 
    perfectly safe if you stay down there. The only time you have to move is when 
    he moves forward to the left side of the screen. He fires trios of bullets at 
    you, so you have move out of the way and actually go up the right side of the 
    screen. When he stops, just move back down and you're safe again.
    The Shadow formation works really well here. When he moves to the left side 
    of the screen, you can go up with Shadow formation and let your satellites 
    hang around up there. When the boss goes back to the right side, he'll be in 
    contact with your satellites, which deals constant damage to him. When he 
    starts to blow up, he'll also start shooting crescents, but they still can't 
    hit you at the bottom of the screen.
    c. Stage 3
    Recommended weapon: S. LASER
    This stage is much longer than the previous two and quite a bit harder. The 
    enemies like to come from all sides and they are considerably harder to kill, 
    which makes S. Laser a great weapon for this stage. Try to destroy as many 
    enemies as you can so you can reach level 4.
    The mid boss isn't too difficult if you know what you're doing. He starts off 
    by firing a stream of bullets which forces you to fly in a circle around him. 
    After that, he fires pairs of crescents that are difficult to fly in between. 
    The red orb in the center is his only weak point and his arms block a lot of 
    your firepower. This I another reason S. Laser is good weapon here because 
    the shots fly through his arms and hit his core easily. Just keep flying in 
    circles around him and stay away from the crescents. After you do enough 
    damage to him, his arms get blown off and his whole body becomes vulnerable, 
    but he fires huge waves up bullets that you can't fly through. When this 
    happens, just stay either right above or below him and change positions 
    accordingly as he flies up and down. Break out in front of him to do damage 
    when he's not firing, or if you're using S. Laser, just stay out of his way 
    and let your weapon do the work.
    After the mid-boss, the level is fairly tame but some of the enemies move 
    pretty quickly, which makes it hard for S. Laser to hit them. Try moving 
    closer so your shots don't have to travel as far, thus making it easier to 
    destroy the enemy ships. You don't want to miss out on the experience!
    The boss can be a little tricky. He starts down in the water and fires single 
    orbs at you. When they get close, they explode in a fan pattern which forces 
    you to fly around them. After doing this several times, he will fire a salvo 
    of tiny missiles that also home on you. These can be difficult to dodge but 
    they can be destroyed. Obviously, you'll have to move down in the bottom left 
    corner to attack the boss in between his attacks, or you can just let S. 
    Laser do all the work (if you haven't noticed by now, S. Laser is a great 
    weapon for this level).
    After dealing some damage, the boss will rise up above the water. He stops 
    using the homing the missiles but now fires lasers out of his "legs" that 
    rebound off the bottom of the screen. This forces you to stay in the upper 
    left part of the screen, dodging the glowing orbs, but makes it much easier 
    to hit him. He stops attacking and becomes invulnerable for a few seconds 
    after he starts blowing up, but once he starts attacking again just keep 
    shooting him until he falls.
    d. Stage 4
    Recommended weapon: S. LASER or ATOMIC (if you've reached level 5)
    This stage is VERY difficult. There is a lot more enemy fire to deal with, 
    including fast moving enemies that bombard the screen with bullets. Atomic 
    works great to erase some of the gunfire but you'll need the Homing formation 
    to make good use of this property. Reaching level 5 at this stage is 
    difficult to do and will have required you to use a continue or two or 
    cleared the first three stages with the secret bonus.
    The first part of the stage lays it on heavy with lots of bullets flying 
    everywhere. The smaller red enemies move quickly and fire fast-moving bullets 
    in an "X" pattern. S. LASER usually won't even hit them, so the Homing 
    formation is very helpful for this stage. If you don't have it yet, try using 
    Rotation so that your satellites have a better chance of soaking up the 
    Once you get close to the colony in the background, things calm down a bit. 
    However, you'll also fight some blue enemies that come on the screen and move 
    forward very quickly while firing at you. There are several formations of 
    enemies that shoot lots of bullets at you, and some will even trap you in the 
    center of the screen, which almost guarantees getting hit. Again, a homing 
    weapon or the Homing formation is great because it lets you concentrate of 
    avoiding enemy fire. There's no mid-boss but after clearing the enemies out, 
    you'll have to deal with the toughest boss yet.
    The boss just flies up and down throughout the entire fight. He start by 
    shooting a wide spread of purple star projectiles. They don't travel too 
    quickly, so you can fly in between them. However, he also sends out 
    satellites that shoot their own S. Laser at you, so avoiding everything can 
    be tricky. He will also form a firing line of satellites that will all shoot 
    at you, so try to destroy them quickly.
    Once the boss is weakened, he gets a little easier to deal with. Now he will 
    fire big crescents you have to fly around. Every few seconds he will shoot a 
    volley of purples stars in lines that you can't fly through, which will force 
    you to either fly up or down. If he fires a crescent as well, you need to 
    move quickly to clear it because you'll still be in motion to avoid the 
    purple stars. Keep up the pressure, and you'll eventually win.
    e. Stage 5
    Recommended weapon: ATOMIC or EXPLODE
    This stage is a little bit of a breather, as it's not as hard as stage 4. You 
    should be level 5 by now, so keep the Homing formation on with Atomic or 
    Explode for great results. A lot of the enemies in the first part of the 
    stage will die pretty quickly, thanks to the Homing formation. However, watch 
    out for the small probes when they line up. They are invulnerable until while 
    they line up and can't be destroyed until they try to ram you. Don't use the 
    Homing formation when they are on the screen because your satellites will get 
    hung up on them.
    The mid boss is easy to beat with the Homing formation. Normally he fires big 
    bullets spreads that are difficult to fly through, but if your satellites are 
    in Homing formation, they will stay right in front of the boss, absorbing all 
    the bullets. The only attacks you have to worry about are the lines of blue 
    projectiles that he shoots, but you'll probably kill him before he even has a 
    chance to use them.
    After that, the stage is pretty tame. The blue comets are destroyed easily on 
    the way down to the planet but they break into chunks, so watch out for them. 
    You'll face more of the smaller enemies that fly at you and then try to ram 
    into you, but these can destroyed right away. You'll also notice some green 
    dots flying up from the background. Initially, they do nothing, but once they 
    get close enough, they move at you quickly while shooting bullets. Also, take 
    your satellites out of Homing formation when they first show up because 
    they'll get hung up on them again.
    The boss is all about performing precise movements repeatedly. You can't hurt 
    him when he first shows up; he just tries to ram you. After that, he becomes 
    a big snake-like ship and only his head in vulnerable. Keep your satellites 
    in Homing formation and they won't have a problem hitting him. After that, 
    the boss simply moves up and down on the screen. Each time he stops he fires 
    a huge spread of blue comets that you have to fly carefully between. After 
    dodging it, move to the side of the screen opposite the boss and do it again. 
    The comets move pretty fast, so this fight is all about getting into a rhythm 
    and dodging the same attack over and over. The Atomic weapon works really 
    well here because it causes the game to slow down a little, making it easier 
    to dodge the boss's attack.
    f. Stage 6
    Recommended weapon: ATOMIC, LASER, or EXPLODE
    The last stage is definitely the hardest. You want firepower over all else 
    here so use a strong weapon. In the first part of the stage, you'll fight 
    beefed up versions of enemies you've fought previously. They give TONS of 
    experience, so you will get one or two extra shields (you should already be 
    level 5 at this point). You'll need them.
    After clearing them, the screen slows down and you enter a corridor, which 
    limits some of your movement. Keep the Homing formation on so that you can 
    kill the enemies in the corridor quickly; the tight spacing makes it 
    difficult to dodge enemy fire. Fortunately, none of the enemies are 
    particularly tough. 
    After getting back out in the open, you will kill a few enemies and then it's 
    time for some bosses.
    The first boss is HARD. He's easy to hit, but all he does is fire fast-moving 
    bullet spreads over and over. It's very difficult to move between them, so it 
    almost becomes a race to kill him before he kills you. He also shoots out a 
    small red orb that floats on the top or bottom of the screen for several 
    seconds before trying to ram you, which makes it even harder to avoid getting 
    hit. But if you kill him, you'll get a bunch of experience, which should 
    hopefully be enough to get an extra shield.
    The next boss takes up the whole right side of the screen. You cannot use the 
    Homing formation here because he shoots out a small ball that travels along 
    the edge of the screen and distracts your satellites; use Rotation or Shadow 
    instead. If you have the Photon weapon, Union also works well. In this fight, 
    the boss just cycles through some hard-to-avoid attacks. His first one fills 
    the whole screen with bullets, so stay on the lower left corner and try to 
    dodge them. After that, he shoots lightning bolts that streak over and down 
    to left, but they're easy to dodge. Then he will start shooting a huge fan of 
    colored shots, but they have bigger gaps, so you can fly right through them. 
    After that, he repeats from his first attack.
    After beating him, you'll probably get another extra shield. You'll then 
    start flying in reverse, so move carefully as you go back through the 
    corridor. Put your satellites back in Homing formation and get ready for the 
    final boss!
    The boss starts out by firing globs of green... something at you. They 
    explode in fans of smaller fragments that you can't fly between, so you have 
    to go around each one. However, he fires them very rapidly and you'll get 
    cornered quickly. Try your best to avoid them as long as you can but you'll 
    probably get hit. After he loses some health, he'll start shooting pink 
    projectiles at you that do the same thing except they travel a little slower 
    and only break into three fragments which make them easier to dodge. You 
    should be able to avoid getting hit at all. Once the boss is almost dead, 
    he'll causes eyeballs to appear everywhere on the screen and then they all 
    fly toward you. This is pretty much impossible to dodge so you just need to 
    kill the boss before he kills you. You should be able to do it if you started 
    the fight with 3 or 4 shields but anything less than that, and you'll have 
    your work cut out for you. Good luck!
