Madness Level: Freed By Psycho
Just before you get to Jayne Wilde, you will move through a grid with a series of cells. You can open these cells to cause a bit of havoc. However, if you stand in an empty cell and project yourself out the door and to the switch outside, you can lock yourself in. Snap back to your body and Vettic will make a comment like 'Well that was clever.' Wait a few seconds and one of the psychos in the cells will run along and pull the lever, freeing you.

Open Doors
On the level 1, Isolation, when you open the elevator, the mirrors show the elevator as being closed, but its doors are still open behind you.

Earth Impact Mini Game
On level 8, Reliance, go into the games room to find a fully-operational Earth Impact mini game. Once this has been done, the game will be able to be accessed on the Applications sub-menu when you pause the game.

Online Chatroom
On level 3, Experimentation, on the PC where you killed the security guard outside the elevator, open the 'Front Desk' applications folder on the desktop. Then, select HyperChat. You will then be able to see what the Guard has been up to, as well as that the person who the guard was talking to continues talking and gets more worried as he does not reply.
