Secrets

 * 1) At the cockpit of the vessel, go towards the left seat and use the second terminal on the left side, then go to the right seat to find a secret compartment containing four armor bonuses and a computer area map. (sector 27)
 * 2) Open the UAC wall next to a berserk pack to reveal a passage leading to a backpack and a medikit. (sector 482)
 * 3) Once you enter the room mentioned in Secret #2, backtrack to the room before it and a silver wall to the north is now lowered. Walk across this wall back into the room and another wall lowers, where you can get two energy cells and a plasma gun. (sector 504)
 * 4) A switch on the ceiling next to the red key can actually be pressed from ground level. Press it to lower the platforms around the red key. When you do, go onto either the northeast or southeast platforms, then hug the walls to the north or south. This will allow you to reach the higher platforms with ammo on them. Two of these platforms count as one secret. (sector 517)
 * 5) Inside the congested corridors at the southern part of the map, you can shoot a wall that has a lot of brown tech wires running across it. After shooting it, it will open and you can collect an invulnerability. (sector 666)
 * 6) By pressing the eye switch in the congested corridors, the nearby window lowers, and going across it makes you teleport into a small room with lost souls. A corridor is revealed while you are in this room, so follow it back to the congested corridors, then make your way until you can open up the exit. After doing so, go just south of the exit, open the next door, and flip the switch next to the door. Run back north, then east, opening the exit door, and running north to a secret room with two boxes of rockets and a medikit. (sector 765)
