"INFILTRATION ROCKS!"
- Cliff Bleszinski, Lead Designer
of the Unreal series

Infiltration was started in early 1999 by Jesse [Warren] Taylor and Chris [Catalyst] Robbers as a semi realistic mod for the original Unreal. It has since moved to Unreal Tournament and become the most realistic combat simulation available.
