Critical Depth - PlayStation

Bermuda Submarine

In the Bermuda level there is a Submarine sticking over the central chasm with a stone projection on the chasm wall supporting the sub. Fire any weapon into either side of the projection, the sub should tilt slightly. Continue to fire weapons into the projection and the sub will continue to tilt until it slides off into the chasm. It should strike the ledge directly beneath it, leaving behind a collection of power up weapons.

Note: This assumes the controller is in the default configuration.

While playing, quickly press L1, R1, L1, R1, Up, Down, Left, Up. You have to be quick to enter this.

Extra Lives

On the Indian Ocean board go to the "double loop" room (there are two giant loops standing up on the floor). Pilot your craft between the two loops and turn toward the wall covered with starfish. Shoot missiles to reveal a secret passageway. Go down passageway and find a room with four crystals on the wall. Shoot each of the crystals until they shoot out shiny disco balls. Once all four are activated, an extra man will appear in the center of the room.

On the Mediterranean board blow up the tall statue and grab some pilot missiles. Dive deep in front of the statue and go through the doorway (it's below critical depth and it has a health in it). Now go up until you hit the ceiling. In front of you is a door with a large keyhole. Shoot a pilot missile through the keyhole (use regular missiles to tell when you're lined up right). Once the pilot missile goes through the hole, guide it around the first corner and hit the pot on the stand. This opens the door. Swim down the tunnels into the room with the statue. Up top on the shelves is a red pot that contains a yellow key. Get the key. Now swim all the way back out and go to the upper temple (the one with the female statues in front). Now that you have the key, the door will open. Blow up the altar on the floor and go down the secret tunnel to the extra man.

Guided Missiles

Press and hold TRIANGLE, then press R1+L1 simultaneously to fire a guided missile. You can now direct it with the d-pad or detonate the missle at any time by pressing R1 and L1.

NOTE: After about 10 to 15 seconds the missle will detonate automatically.

Infinite Weapons

Press L1, R1, L1, R1, Up, Down, Left, Down while playing.

Invincibility

For invincibility, press L1, R1, L1, R1, Up, Down, Left, Right while playing.

Killing the Eel

In the Medditeranian there is a giant electric eel guarding the threshhold. Although normal attacks can eventually kill it, a stun blast is much faster.

Lay a Mine

Hold R2 and press Right, Left, Down.

Note: This assumes the controller is in the default configuration.

Quad Damage

To do four times the normal damage, press R1, R2, R1, R2, Up, Down, Up, Down while playing.

Quick Fire Combo

Press and hold both weapon select buttons (L1 and R1 by default.) A menu of directions and button symbols will appear besides your weapon list.

Push the direction or button symbol next to the desired weapon to make it fire. By quickly pressing a series of buttons or diretions you can unleash devestating combos. Unfortunately, each weapon fired in this manner drains your power meter bar. So doing this maneuver can leave you without shields or turbo.

Secret Room and Extra Life

On the second level, at the Battle in the Red Sea, go inside the temple and find the room where there are seven statues of kings sitting upon thrones - three on each side of the room and one in the middle, sitting on an incline going down. You can hit the other statues for weapons, but the statue in the middle is the important one. Hit it with a remote detonator or something powerful. It will blow up, revealing a secret passage to a hidden room. One of the statues in this room contains the extra life.

Stun Blast

Hold R2 and press Right, Left, Up.

Note: This assumes the controller is in the default configuration.

Super Weapon Power-up

In Fort Apocalypse, go to the southern triangular tunnel. Shoot out the central floor area of this tunnel to reveal a hidden alcove and Heal Power-up under the floor.

Go into the alcove and attack the southern wall until it blows up revealing another passage. Follow this passage to a room with a sucker weapon where the passage forks to the left and right and slopes down toward critical depth. Either fork will lead you to a glowing yellow sphere, use turbo to dive down and grab this, you will be rewarded with two of each weapon.

This power-up is well below critical depth so be sure you have enough health to survive. Depending on your character's armor and speed you will take between 40% and 60% damage.

Surface Mine

Hold R2 and press Right, Left, Down.

Note: This assumes the controller is in the default configuration.
