Get Slapped
This isn't really a cheat but an alternate ending. After Brink accidently kills himself go back to the crystal machine and insert the eye piece once again. Take two more crystals than you already have. Go back to the machine and attempt to work it. When Maggie dies resurrect her with the life crystal and watch the alternate ending. Observe the part when Boston gets slapped by Maggie after she is brought back to life. Funny Stuff!!!

Boston's huge muscles
Press Control + B to make Boston flex his muscles, producing an often funny reaction from his teammates. This only works if you are not in space.

Alternate Ending
After Brink dies the second time, use the eye piece in his machine once more to get two extra life crystals. Then, when Maggie dies, use a life crystal on her to view an alternate ending at the end.
