To complete the level, you need to hit a switch in each of the towers (the switches cause what look like docking clamps to disengage which you can watch outside the windows of these towers.) and then hit all 3 switches in the plasma room. Return to the terminal at the beginning of the level to leave.
Keep returning to the save terminal and shield recharger at the beginning of the level. You'll appreciate it later.
- PERSONALITY CONSTRUCTS SEEKING CYBORGS
Down the very narrow corridor, there is a secret panel that opens to reveal a circuit that you can break. When you break this, the platform that you are standing on drops down to reveal a place to get an alien weapon and more circuits. The space between the circuits opens to reveal a hidden communications terminal, which will teleport you back to the beginning of the level.
