    INTRO SEQUENCE: "IN THE LAST EPISODE" (1 secret)
    Note: Secret not found. It would seem that the player cannot influence what 
    happens in the intro. However, when you access the "Statistics" section of 
    Sam's computer display at the start of the next (first playable) level of the 
    game, you will notice that the current total number of secrets stands at 13 
    whereas the subtotal for level 1 is only 12; there is a discrepancy in kills 
    statistics as well. That means that you have already missed one secret, and 
    yet you have not even started playing.
    
    MISSION ONE: MESOAMERICA
    
    LEVEL 1: SIERRA DE CHIAPAS (12 secrets)
    CRASH SITE
    1. From the starting position, dive all the way down to collect a weapon in 
    the lit spot near the bottom.
    2. Once you surface from #1, get onto the small peninsula with a tree to 
    collect an armor piece.
    3. Still on the #2 peninsula, walk towards the phone booth to "discover" it. 
    (You might as well get inside and make a call.)
    NEAR THE FIRST TEMPLE
    4. Skirt the outer left wall of the temple. Find a darker section on the wall 
    near the spot where it meets the mountain. Blast it to discover an entrance.
    5. Get through the hole you created in #4, and go down to discover a "hall of 
    fame." (Stick around for a silly presentation.)
    6. From #5, get outside and walk straight to discover remains of the crate 
    bus that collided with Sam's spaceship in the intro.
    7. From #6, continue up the slope until you collect an ammo pack.
    INSIDE THE FIRST TEMPLE
    8. At the end of the corridor with hazy sunlight coming through the openings 
    in the roof, there will be a T-junction. Turn left, away from the corridor 
    with crushing blocks. Go on to find a "secret Mental's room." (Use the jump 
    pads marked by lit letters, in this order: M, E, N, T, A, L; a niche with a 
    healing pack will open on the other side. After you collect the pack, you can 
    jump on any pad to get back.)
    SECOND VALLEY
    9. When you exit the temple, you will notice a pit not far off. There is a 
    ledge in the pit that you should jump down to, to collect a weapon. (When 
    done, drop to the lower ledge to be teleported.)
    10. After you pass the first suspension bridge and before you reach the 
    second one, look for a conspicuous rock on the mountainside on your left. 
    Blow it up to discover a cave. (Go inside, dive, and swim on.)
    11. When you emerge from the water passage you entered in #10, cross the 
    suspension bridge to collect a healing pack on the other side.
    12. When you reach the second temple, dive into the pond to find another 
    healing pack in the lit spot near the bottom.
    
    LEVEL 2: VALLEY OF THE JAGUAR (8 secrets)
    Note: One secret not found. Maybe non-secret A is actually a secret too 
    stubborn to register.
    STILL INSIDE THE TEMPLE
    1. When you get across the cave outfitted with both floating and stationary 
    jump pads and find yourself on the final ledge, jump onto the smaller ledge 
    located slightly lower, on the left, to be catapulted onto the overhang above 
    the larger ledge for some ammo.
    VALLEY
    Non-secret A. As soon as you get out of the temple into the open, turn around 
    and you will notice a camouflaged ledge on the hill slope. Blow it up to 
    release an invulnerability power-up.
    2. When you get to the top of the pyramid to the right of the entrance, slide 
    down to the nearest ledge on the right side and blast the darker section on 
    the wall to reveal a weapon.
    3. Proceed to the corner of the valley where you can see a huge ball sitting 
    at the top, to collect an armor piece.
    4. Head for the corner of the valley diagonally across from #3, where you can 
    see the "Crollywood" sign, to get a "movie studio" secret registered.
    5. Go inside the stone hut to the left of the pyramid that has an antenna on 
    top. There is a small ammo depot there.
    6. From #5, circle the base of the pyramid to collect a healing pack, which 
    is located where its right side meets the grassy slope.
    INSIDE THE MOUNTAIN ON THE LEFT SIDE OF THE VALLEY
    7. After you pass the windy room with spikes on both side walls, you will 
    find yourself in a corridor with four health vials. At the end of it, there 
    is a bounce pad in the alcove on your left. Jump up and collect the items 
    sitting on the overhead beam.
    
    LEVEL 3: THE CITY OF THE GODS (15 secrets)
    FIRST LARGE COURTYARD
    1. When you leave the ammo depot (where you start) and enter a courtyard, 
    walk to the right and cut down the tree in the corner closest to the 
    entrance. This will reveal a wedge-shaped area between the stone hut and the 
    perimeter wall. Collect the healing pack there.
    2. In the right-hand corner furthest from the entrance: In the area between 
    the building with facade columns and the perimeter wall, find a darker 
    section on the building and blast it to find an armor piece.
    3. In the left-hand corner furthest from the entrance: Get behind the corner 
    building to find a health pill. Pick it up to activate a "secret bloodbath."
    4. Get inside the building where you are supposed to find the scary mask; it 
    is on the same side of the courtyard as #3. Blow up the fallen pillar to 
    reveal a corridor.
    5. Follow the corridor you found in #4 into a room with cannon balls. Destroy 
    the central pillar there to find a weapon.
    6. Visit the remaining corner of the courtyard to collect an ammo pack.
    NEXT LARGE COURTYARD
    7. On the left side, behind the third tree from the entrance, there is an 
    unobtrusive twinkling teleport that takes you to a "yard of strange-looking 
    heads."
    Non-secret A. In the #7 secret, blast the "strange-looking heads" for a 
    higher kills count.
    8. Back in the courtyard you teleported from, go behind the large building 
    opposite the entrance to collect an ammo pack.
    VILLAGE AFTER THE "VERY LONG RUN"
    9. Find a hut with a snake ornament on the roof. Enter the hut (and sidestep 
    quickly) to discover a "lost Spanish cannon." (Destroy the canon.)
    10. Reach the section of the perimeter wall that is directly opposite the 
    entrance. There is a healing pack behind the hut that stands at an angle to 
    the wall.
    UNDERGROUND COMPLEX
    11. In the village, you enter the building that leads underground. In the 
    middle of the first hall, there is a healing pack pulsating just under the 
    ceiling. Blast the stone piece it is sitting on to collect it.
    Non-secret A. After you get through the door at the end of the hall just 
    mentioned, there will be a sloping passage. If you jump over the rails there, 
    you will find yourself in a chute. As you slide down, several power-ups get 
    spawned. However, the chute ends in spikes. Once or twice I was able to jump 
    out of the chute before getting killed by the spikes (I even managed to grab 
    a couple of items before escaping). I think you should bump into a side beam 
    to achieve this feat. It happens really fast, so I am not certain. Maybe 
    there is an easier way.
    12. In the hall into which you are dropped from the sloping passage mentioned 
    in the non-secret, blast the central section of the wall on the right to find 
    some items.
    13. Repeat #12 on the left wall to discover a "secret poker game."
    14. In the windy corridor with rectangular holes in the floor and round holes 
    in the walls, enter a secret passage through the first round hole on your 
    right.
    15. In the lava cave, go to the right, towards the half-submerged building. 
    There is a low-lying ledge between the building and the rock wall, with an 
    ammo pack on it.
    Non-secret B. In the pit where everybody jumps up and down, picking up a 
    second health pill creates temporary "gravity off" conditions, meaning that 
    everybody will stop at different altitudes for a while. I think this 
    procedure can be repeated indefinitely, since the pills are respawned.
    
    LEVEL 4: SERPENT YARDS (10 secrets)
    FIRST COURTYARD
    1. Go right from the entrance and collect an ammo pack in the corner.
    2. Same as #1, only in the left corner: Pick up the armor shard there to 
    discover a "suicidal plant."
    3. After the explosion in which red mechanoids get released from a 
    rectangular enclosure, search inside the ruins for a healing pack.
    FORCE-FIELD PASSAGE
    4. After you cross the force field, go behind the stone hut on the right to 
    collect an ammo pack.
    MOON PYRAMID
    5. Approach the flattened head to the right of the structure that housed the 
    mask of Ix Chel (only possible after you capture the mask). Blast the head 
    after it attacks you (or just let it explode) to get a healing pack.
    6. From #5, walk to the rear of the Moon Pyramid and use the switch there to 
    activate a "mega ultra explosion."
    BACK IN THE SNAKE-GATE COURTYARD
    7. Before leaving through the Snake Gate, get inside the "bad head" building 
    (accessible only after you pick up the Ix Chel mask) to collect an armor 
    piece.
    COURTYARD PAST THE SNAKE GATE
    8. In the far right corner, collect a health pill to reveal a "secret 
    watcher."
    9. Shoot the watching eyes spawned in #8, to activate a "mighty kamikaze."
    LAST HALL
    10. Destroy the two jaguar statues on the overhang above the exit to release 
    a healing pack.
    
    LEVEL 5: THE PIT (10 secrets)
    FIRST CORRIDOR
    1. Behind the fourth pillar on the right, there is a darkened passage to a 
    spot with a healing pack.
    PAST THE "DANGEROUS FORCES" HALL
    2. At the end of the first corridor with arches, there is an twinkling 
    teleport in the lamp on the left. Use it to collect an armor piece.
    STONE BRIDGE STRUCTURE
    3. Near the end of the first bridge, jump onto the side ledge on the right to 
    find a twinkling teleport just off the bridge. Jump into it to get some ammo. 
    Use the nearby teleport to return to the bridge.
    4. Right after you enter the stairwell tower, go right to find a healing pack 
    under the staircase.
    5. In the seventh window up the staircase, there will be a mini-version of 
    the red reptiloid demon. Kill it to release a healing pack.
    6. At the L-shaped intersection on the upper bridge, destroy the two lamps on 
    the first (as you approach) outer ledge to summon "annoying Pinky's lost 
    brothers."
    7. From #6, go to the other ledge at the same intersection and use the 
    "secret broken teleport" in the right lamp. (Once teleported up, you will 
    have to jump towards the armor piece to get it.)
    PAST THE "NEWTON'S NIGHTMARE" TUBE
    8. In the corridor following the room with a stone head and two Serious 
    bombs, destroy the eight lamps to have some ammo spawned.
    FIRST COURTYARD
    9. After you repel the first enemy attack, the gate with the snake ornament 
    will be opened. Walk up the staircase, turn right, and use the teleport in 
    the corner lamp. Jump down to the roof of the booth where you have been 
    teleported, and collect some "rocket-festival gear."
    10. After #9, quickly jump off the booth onto the perimeter ledge and then 
    towards the healing pack sitting between the two nearby lamps. A "rocket 
    festival" will be activated.
    
    MISSION TWO: MESOPOTAMIA
    
    LEVEL 6: ZIGGURAT (10 secrets)
    ZIGGURAT PROPER
    1. From the starting position, walk around the building to collect a weapon.
    2. In the hall with spiral staircases on the central pillars, one of those 
    pillars has a side opening. From the opening, you can jump down safely and 
    collect the healing pack that you may have noticed from upstairs earlier.
    FIRST WINGED-HORSE COURTYARD
    3. After you enter, head right and look for a darker section on the wall of 
    the ziggurat where it meets the perimeter wall. Blast it to find a healing 
    pack.
    4. As in #3, only to the left of the entrance: Pick up the ammo pack sitting 
    in the corner to discover a "suicidal avenger plant."
    5. There is a darker section on the perimeter wall behind the tower housing 
    the "hawk wing" artifact. Blast it to find an armor shard (and a monster).
    BUILDING AT THE END OF THE COURTYARD
    6. When you enter, you will notice a supply depot through a grating on your 
    right. After you unlock the door on the same side, enter and go to the right. 
    Move into the dark area between the first two pillars on the right wall; you 
    will find the items you have noticed.
    FIRST RESIDENTIAL AREA
    7. There is a solitary plant in the desert at some distance from the village, 
    to the right of the entrance to this area. Collect the speed power-up there.
    8. Still near #7, blast the plant to find a damage power-up.
    COURTYARD IN THE RIGHT SECTION OF THE SECOND RESIDENTIAL AREA
    9. Walk to the wall opposite the entrance, past the lone statue of a winged 
    horse. Turn left there and collect the health pill near the two-story 
    building to enable a "Boxing Barry" secret. Then, walk along the building 
    until you hear a squeaking sound. Look up and shoot off the flapping window 
    shutter. A green reptiloid will be spawned on the roof of the opposite 
    building, only to be knocked out.
    10. After you touch the green stone, exit the tower housing it and go 10 
    o'clock. Blast the darker section of the wall in the niche and enter. Look 
    up, and you will see a wooden platform up above. Blast it, too; an 
    invulnerability power-up will be released.
    
    LEVEL 7: THE ELEPHANT ATRIUM (12 secrets)
    STILL INSIDE THE BUILDING
    1. From the first hall, go through the door on the right, turn left, go up 
    the staircase, and make two lefts. You should be on the platform overlooking 
    the first hall. Use the bounce pad on the left to get on top of a pillar and 
    jump your way to the healing pack on the other side.
    ELEPHANT SQUARE
    2. On the left side of the outer wall of the "Holy Bathhouse" (the building 
    with two warrior statues), blast the darker section to find an armor piece.
    3. If you go left from the entrance to Elephant Square, you will find a 
    health pill by the perimeter wall. Pick it up. Several mechanoids will be 
    spawned, and the wall will be partly blown up, revealing a secret yard.
    4. When you reach the end of the #3 yard, you will find a detonator switch. 
    Use it to destroy a pyramid.
    SMALL COURT PAST THE DOOR OF PURITY
    5. Now, this one is really frustrating. When you have eliminated the initial 
    enemy presence, six Kleer skeletons will be catapulted, one by one, into the 
    court from behind the perimeter wall to the right of the entrance. If you 
    succeed in taking each one out before it touches the ground (only possible 
    with the sniper rifle, I think), you will receive a congratulatory message.
    NEXT ACCESSIBLE COURTYARD
    6. From the entrance, make two rights and pick up the ammo pack. A "mutated 
    plant" will appear.
    7. As in #6, only on the left: You will notice a darker section on the wall 
    of the entrance building. Blast it to find an armor piece.
    8. Diagonally across from #6, there is a niche in the perimeter wall, with a 
    healing pack.
    COURTYARD WHERE YOU FIRST SEE THE GOLDEN ELEPHANT STATUE
    9. Go around the pit with the statue and use the switch on the wall to unseal 
    a secret yard.
    SECRET YARD
    10. You will know you have reached the secret yard (that you unsealed in #9) 
    when you see a red phone booth. Go to the end of the yard to find some useful 
    items.
    LAST WINGED-HORSE COURTYARD
    11. To the right of the horse statue, there is a building with a locked door. 
    If you go to the left of the statue, you will find a switch to the left of 
    the up staircase. Use the switch to unlock that door. (Visit the building, 
    naturally.)
    12. Approach the horse statue from behind. Get as close as you can to its, 
    ahem, rear. When the "Use" message appears, press the Use key to harness some 
    "secret horse power."
    
    LEVEL 8: COURTYARDS OF GILGAMESH (11 secrets)
    FIRST COURTYARD
    1. Go to the right of the entrance and use the two ledges on the wall to get 
    onto the otherwise inaccessible platform. You will find a healing pack there.
    NEXT COURTYARD
    2. Dive into the left pool and go through the only opening without a grating. 
    Collect the ammo pack.
    3. Go to the other pool and collect the ammo pack sitting by the pool.
    4. Dive into the #3 pool. Right after the underwater hall with a pillar in 
    the middle, you will find yourself in a room where you can: (a) surface to 
    catch some air; (b) swim all the way down; (c) go to the right towards the 
    exit. Opt for (b) first, then go straight and swim up to find a secret room.
    COURTYARD AFTER THE "NASTY DIVE"
    5. Look for two golden domes located outside the courtyard, and you will 
    notice a red-and-white practice target on a tower that is also located 
    outside. Shoot the target, and a niche on the right side of the perimeter 
    wall will be opened.
    6. From #5, walk along the perimeter wall until you reach the corner, then 
    turn left. Collect the ammo pack behind the pyramid to discover "a mutated 
    plant and friends."
    7. From #6, walk along the perimeter wall some more, and you will reach the 
    point opposite the niche opened in #5. Blast the darker section to reveal a 
    "don't push" detonator switch. (Ignore the message and push the switch.)
    BUILDING YOU ENTER AFTER GETTING THE GOLDEN LION STATUE
    8. Go through the opening on the right, and you will reach a hall with a 
    pulsating heart. Collect it to get the secret registered.
    9. When you have fought your way through a particularly nasty narrow corridor 
    (you will know), walk to the left to find an armor piece in a niche.
    MOVING PLATFORM
    10. At some point, the "leap of faith" platform will be passing under a small 
    ledge with a pulsating heart (on your left). If you time your shot correctly, 
    you can blast the ledge so that the heart falls onto the platform. (I think 
    your cue should be Sam's second utterance while under attack, something like 
    "Now I am seriously serious.")
    LAST COURTYARD
    11. There will be an outside tower on your left. Shoot the red-and-white 
    target on it to observe some wild hearts and eventually get one.
    
    LEVEL 9: TOWER OF BABEL (10 secrets)
    CEREMONIAL HALL
    1. Find a niche in the wall to the left of the exit to collect some ammo.
    CHAMBER OF COSMOS
    2. Between the second pillar (from the entrance) and the staircase, jump down 
    into the lower niche to collect a healing pack. (You will be teleported back. 
    This secret can be obstinate, so you may need several tries to make it 
    register.)
    [Nether Star's comment: The reason it is obstinate is because the teleport 
    back to the stairs is directly in front of the healing pack.  You must 
    approach it from the side or the rear.]
    3. After the narrow bridge and before another up staircase, visit the lower 
    platform to collect some ammo.
    4. In the lower area, where you get via the elevator, shoot any of the mouse-
    sized holes to summon "deadly midgets."
    5. In the area where you slide down towards the exit door, go to the floor 
    lamp located on the right side of the slide. Use the bounce pad behind the 
    lamp to be catapulted onto a platform where you find some ammo. (There is a 
    teleport in the corner there to take you back.)
    FIRST COURTYARD
    6. In the left section of the courtyard, there is a pillar in the perimeter 
    wall, with a bas-relief of a warrior. At some point, its eyes start to glow. 
    I do not think you have to wait for that, though; just blast the pillar at 
    any time to find a "passage to Egypt."
    Non-secret A. Once on the movie set in the #6 secret, you can destroy the 
    mini-version of Ugh-Zan III to spawn an armor piece.
    Non-secret B. Still in #6, a healing pack can also get spawned after some 
    additional destruction, but I am not certain what exactly triggers that. One 
    thing for sure: you may not kill the mini-version of your own character, Sam.
    COURTYARD PAST THE ONE WITH THE SECOND TABLET OF WISDOM
    7. Go to the perimeter wall directly opposite the entrance, behind the flat 
    statue. There is a darker section on the wall of the building there, on your 
    right. Blast it to collect an invulnerability power-up.
    COURTYARD PAST THE ONE WITH THE THIRD TABLET OF WISDOM
    8. Go 1 o'clock from the entrance and pick up the health pill in the corner 
    to summon a "mighty gizmo."
    BACK IN THE FIRST COURTYARD
    9. When you return to the "magnificent view" courtyard, go to the left of the 
    base of the entrance to the Tower of Babel, to collect an invulnerability 
    power-up.
    10. Rather than going into the Tower of Babel right away, revisit the 
    courtyard to the left of it - the one where you got the first tablet of 
    wisdom. Go in for a "secret round two," i.e., for another raid through the 
    courtyards surrounding the tower, following the now-familiar path.
    
    MISSION THREE: EASTERN EUROPE
    
    LEVEL 10: THE CITADEL (16 secrets)
    Note: Before starting the level, read secret 11 below.
    STARTING COURTYARD
    1. The third hut on the left side has a squeaking door. Destroy the door 
    (with the knife) to collect a weapon inside.
    BUILDING AT THE END OF THE COURTYARD
    2. Soon after you leave the Kill-o-Matic room via the elevator, you will 
    notice a niche (with a switch) in the wall. Come closer, and a "Use" message 
    will appear, as will a green reptiloid behind you. Use the switch then, to 
    knock out the monster.
    STONE BRIDGE
    3. Jump off the bridge onto the rock base of the first stone pillar on your 
    left to collect a healing pack. (Use the glowing bounce pad to get back.)
    FIRST COURTYARD PAST THE BRIDGE
    4. Go behind the hut in the corner to the right of the entrance to collect an 
    ammo pack.
    5. Same as in #4, only at 2 o'clock from the entrance.
    6. In the smaller, enclosed area to the right of the courtyard, discover two 
    sets of graves by the perimeter wall. (You may open each grave, if so 
    inclined.)
    NEXT COURTYARD
    7. In the far left corner from the entrance, there is a dead tree. At some 
    point, apparently after you collect the nearby napalm capsules, the tree 
    turns into a "secret jumping plant."
    SECOND COURTYARD AFTER THAT ONE
    8. In the far right corner from the entrance, there is a barrel by the 
    building. Destroy it and get behind the building to obtain an invulnerability 
    power-up.
    9. Diagonally across from #8, to the right (if you look from your #8 
    position) of the entrance, there is an area with a phone booth behind the 
    stone hut. Move in to find some ammo.
    ROOM WITH BIG COGWHEELS
    10. From the entrance, go through the small opening on the left, into the 
    water. Dive, turn around, and look for a niche with a healing pack.
    CLOCK COURTYARD
    11. To discover this secret without resorting to a cheat, you need to get 
    from the level's starting position to this courtyard in time for the clock to 
    strike midnight. You start the level at about 11:45 p.m. (virtual time), 
    which makes it a tough task indeed, especially since you probably want to 
    check the previous areas thoroughly enough to discover the other secrets. A 
    "midnight mega secret" gets enabled at midnight: the door of the hut located 
    to the left of the entrance ledge opens, providing access to some very useful 
    "midnight items." Entering the hut gets the secret registered. You have 1 
    minute to claim the goodies, after which the door closes again. I wonder if 
    the door opens again, e.g., if you leave the game running for 24 hours, but I 
    am not obsessed enough to try that. Anyway, if your only concern is to make 
    the secret register, you can go behind the hut and get close enough to its 
    rear wall. For some reason, you will pick up the damage power-up from inside 
    the hut and get the message about finding the "midnight items."
    12. Go behind the clustered buildings to the right of the exit gate, to find 
    an armor piece.
    NEXT COURTYARD, WITH A DRAWBRIDGE
    13. Collect some ammo behind the hut to the left of the courtyard entrance.
    14. Diagonally across from #13, there is an armor piece behind the corner 
    hut.
    WATER CAVE
    15. After you fall from the chute into the water, search the bottom for 
    items. The secret registers when you collect a 50-point healing pack.
    KILL-O-MATIC HALL
    Non-secret A. Before any enemies appear, you can blast the thumping spikes 
    off the pillars and blow up the pillars themselves for better fighting 
    conditions.
    LAST COURTYARD
    16. There is a barrel in a corner, which you can destroy to reveal an armor 
    piece.
    
    LEVEL 11: LAND OF THE DAMNED (13 secrets)
    FIRST VILLAGE
    1. One of the huts at the start of the village, on the left side, has a 
    squeaking door. Blast the door and step inside to collect a damage power-up.
    2. Press the switch on the windmill to summon a "secret Santa."
    Non-secret A. Find and shoot the running Santa for a present. If you choose 
    to dispatch him with the single revolver (or better yet, the flamethrower, 
    using short bursts; that will sometimes produce an amusing effect) rather 
    than a more devastating weapon, you will be able to maximize Santa's gift 
    output.
    3. In the second half of the village, beyond the windmill, look for Santa's 
    feet in a chimney. Blast the chimney to unplug the "secret jammed Santa."
    4. There is a snowman close to #3. Shoot it to find an armor piece.
    SECOND VILLAGE
    5. Pick up the armor piece in front of the bespectacled snowman, who will 
    then attack you. Terminate this "snowman avenger."
    6. The hut just to the right of the #5 avenger has a squeaking door. Blast 
    the door and step inside to collect an invulnerability power-up.
    7. Not far away from #6, on the right side of the village, there is a snowman 
    with a switch. Use the switch to summon another "secret Santa."
    Non-secret B. Same as #A.
    YARD WITH THE MOUNTAIN ENTRANCE
    8. Shoot at the snowman repeatedly to find that you were dealing with an 
    "incredible shrinking snowman."
    FIRST LAVA CAVE
    9. In the middle of the stone passage that serves as a bridge, there is a 
    gap. Drop through the gap into the familiar twinkling, to be teleported to a 
    healing pack.
    SECOND LAVA CAVE
    10. When you enter, you should be able to discern a glow on a stone ledge up 
    ahead. Blast the ledge, and an ammo pack will fall onto the passage below, 
    where you will pick it up when you reach it. (You may also destroy the ledge 
    when you get across the lava to the other side of the cave, but the ledge 
    will be even less visible then.)
    11. Before leaving this cave, go to the left of the exit and then to the left 
    of the boulder that gives the impression of blocking the passage. Follow the 
    narrow ledge to collect a weapon.
    THIRD LAVA CAVE
    12. When you reach the point where you have to use floating platforms to 
    proceed, get on the one on your left that is furthest away from your position 
    and closest to the two-pronged solitary rock standing in the middle of the 
    lava lake, also on your left. The platform will start sailing towards the 
    rock. As you get nearer, you will notice a ledge by the rock, with some 
    goodies. Grab them when you feel it is safe (the armor piece counts as a 
    secret), and jump back onto the platform, which will make a full circle 
    around the rock. (You may want to forgo the platform and just wade to the 
    ledge, since the platform moves rather slowly and you are open to enemy fire 
    all along.)
    13. When you cross the arched bridge that leads to the exit from the cave, 
    circle its base to collect a healing pack.
    
    LEVEL 12: THE GRAND CATHEDRAL (6 secrets)
    CORRIDOR OF DEATH
    1. Turn to the right from the entrance and blast the darker section on the 
    perimeter wall to discover some items.
    2. In the far right corner of the second leg of the corridor, there is a dude 
    with an Afro looking out from a window. Shoot him to have a damage power-up 
    launched from behind the perimeter wall onto the passage.
    3. Towards the end of the third leg of the corridor, blast the darker section 
    of the left perimeter wall to discover a teleport to a "pumpkin field" (go 
    there).
    4. In the sixth leg of the corridor, blast the darker section on the left 
    wall to discover another teleport, which leads to an "embryo museum" (again, 
    go there).
    5. At the start of the seventh and final leg of the corridor, look to your 
    left. In the middle window of the bastion you will see a Scythian witch-harpy 
    mooning you. Kill the witch to have an invulnerability power-up launched onto 
    the passage from behind the perimeter wall.
    FINAL COURTYARD
    6. At some point during the final battle, you will receive a message about a 
    pink secret having been enabled. That refers to the pink section of the 
    perimeter wall just to the right of the bounce pad on the right side of the 
    courtyard (if you are looking from the starting position). The message means 
    that you can now approach that section and just crawl inside to retrieve a 
    healing pack, at which point the secret will register.
    Major spoiler. Apparently, Mordekai the Summoner summons his minions and 
    teleports himself back and forth only when you are in his line of sight. If 
    you are wise (or cowardly) enough to choose your position correctly, i.e., 
    hide somewhere behind the protruding features of the cathedral on either 
    side, you should be able to dispatch the monster pretty easily, without being 
    bothered by lesser enemies - or the boss himself. Peek outside just enough to 
    be able to shoot at his shoulder or some other part of his anatomy. The 
    sniper rifle is your best bet.
