Deviation, a machinima from Hard Light Films, proves that there's always a pill in every group. Or, as they describe it:

The short film 'Deviation' was shot using an online game engine with the virtual actors and director never having met one another.

Macintyre, an online-game character and member of a four-man counter-terrorist squad, attempts to break out of the cycle of futile violence that has been his sole existence.
Dropped into the middle of a mission and faced with the prospect of climbing into an ambush at the end of a manhole tunnel, Macintyre strives to convince the other squad members that there is another way...

It's actually very well done. Go check it out.
