Previously called the "QUAKE 3 Engine" and one of the most successful licensed engines in history, id Tech 3 was the engine used to create games such as Quake II Arena, Return to Castle Wolfenstein and Soldier of Fortune II: Double Helix. id Tech 3 introduced shaders, curved surfaces, 32-bit color, special effects, bleeding-edge networking and super-smooth speedy hardware rendering.

Call of Duty 2 doesn't use the iD Tech 3 engine. :\ The original did but everything following 2 uses Inifinity Ward's proprietary engine.

IW Engine is a modified id Tech 3, it still uses the Quake 3 level editor and map format and still has network code from Quake 3. The biggest change with IW Engine is it's custom animation system and it's new rendering engine.
