Learn 2 gaming history, dudes :P

What engine does Call of Duty 4 run on?

IW (Infinity Ward) 3.0 engine. It is basically a modified version ID Tech 3 engine by ID Software. First game based on ID Tech 3 was Quake 3 arena in 1999. 

I know, I was asking mr gaming history there :P

Edit: this might be of interest to you FPS fans out there -

How is any of this relevant to the actual interesting bit of Activision's history? (Winning in courts opening up third party development in the Atari Era)
