Leave the prison cell and head for the lit heading up at the end of the cell block. If you wish you can instead head downstairs by pressing against the walls in the darkened area, eventually you’ll activate the lift. Downstairs a prisoner awaits execution. If you touch the computer console at one side of the room you’ll start the electrocution mechanism.
Take the lift upstairs and get the universal translator on the floor at the top. Investigate the cells, in one is a Flare and several diaries, which you can use the Universal Translator to read. Look for a tunnel on the upper floor of the cell block and follow the tunnel to the bridge of the ship. Enter the door labelled "Armoury" and get the Health Pack. A force field protects an Assault Vest, get underneath the button hanging from the ceiling and jump so that you hit it with your head, the force field is lowered, so get the vest.
Drop down onto the lower level of the bridge, find another health pack, and keep descending until you find another corridor with a hanging electrical cord, avoid it by sticking to one side and you’ll find a sick bay where you can get another health pack and can translate more messages. Proceed through the ‘med lab’ and collect another pair of health packs. Exit through a small tunnel, the door locks behind you, and eventually another door opens. You will see a ‘SKAARJ’ running away. Pick up the dispersion pistol on the floor and proceed down the corridor until you find ‘Area C’. Find the spot marked First Aid Station and shoot the glass for the health pack. Enter the small brightly lit tunnel to an area with computer consoles surrounding a large button. Press it to lower a lift, ride the lift upstairs and find a doorway, go through it to a small room, shoot out the doors and pass through into another little room, shoot the glass panel in the wall to open a trapdoor. Drop through it to complete the level.
