The access code for part 2 is-"786169" PART 1: Move back slightly when you encounter a mine. They're much less sensitive from the rear. Avoid jetski bullets by jumping or ducking. When approaching sharks, move the up and down nut left and right. Octopi and sea monsters are easily thwarted by holding down fire until both missiles are ignited and then releasing. Struggle to dock with a submarine? Put a mini-sub in the gap between the tailfin and the hull, face the left of the screen and move upwards slowly, the computer takes over the docking procedure for you. PART 2: The code is 948411. Arrows indicate the direction of the lifts. Kill white marines and flamethrower troops to get more ammo. Stand over the body and search thoroughly. To get the code of an official, you must shoot him with a gun, not a flamethrower. To enter computer codes, stand by a terminal, push up and you'll be asked for a code. Two of the codes are: transmit message: 1st or 2nd transmission official open door: 1st or 2nd machine official to open the reactor door, use the terminal next to the reactor. The computer confirms the bomb is planted. Go out, use the same terminal you used to open the door and transmit the following: "OABERYAMD". Now type "END" at the ready prompt and run like hell to the conning tower.
