3. Destroy master control console
4. Use radio to contact Jack Wade
5. Minimise scientist casualties

The Caverns cheat is obtained on 00 Agent. It isn't easy, mainly because the level itself isn't easy

a. Destroy inlet pump controls

In one of the first rooms, go down the stairs; there are 2 consoles on one side of the corridor and 2 consoles on the other.

b. Destroy outlet pump controls

Two approaches are possible. After the crates room that follows the big climb, you can take the normal path, meaning don't go down and turn right (1st door). There's a machine gun and enemies to kill. The 4 consoles are downstairs, one on the left, 2 in the middle, and 1 on the right. Personally I prefer to go through the secret passage. Go down the stairs and head to the back; there's a room full of crates on the floor (containing lots of weapons, destroy them with mines). At the back there are lockers hiding a corridor if you destroy them. You reach the console room if you also destroy the lockers at the end of the corridor. Through this passage there are only 2 guards to kill, and they'll often come toward you when you destroy the lockers (you can even place a mine right after doing so). Once the 2 guards are eliminated, destroy the 2 consoles in line with the corridor, then the one just to the left after the lockers. The fourth is right at the back on the right and not visible. Rush in, destroy it, and leave through the secret passage (you can also destroy just that one through the "normal" door: open the door and take it out with the zoom).

c. Destroy master control console

Follow the big walkway to the end after the crates room that follows the big climb. Open the doors to arrive in a room with a recessed area. In this recess are guards, the radio, and the last console. This objective comes before objective D, but honestly it's better to do D first. So clear the recess by shooting heads from a distance. Blowing out the left window quickly can be a lifesaver, because the guards throw grenades that often don't get through the windows and everything explodes. Be careful, because the canisters are explosive and not very sturdy. Once all the guards are dead, do objective D and blow everything up.

d. Use radio to contact Jack Wade

The radio is in the recess. Just press B when you're in front of it. It just needs to not have exploded before you get there, which isn't always so simple.

e. Minimise scientist casualties

Wenn 3 Wissenschaftler sterben, haben Sie verloren.

Once the 4 objectives are complete, take the big door facing the radio. Normally you should have obtained the key from a guard. Then go left and eliminate the 2 guards. Open the doors carefully and quickly destroy the 2 gun drones, then rush to the exit while spraying bullets. If you have enough ammo, I recommend the RCP-90.
