IW Engine

That would be IW as in Infinity Ward, the legendary developer behind arguably the biggest franchise of this generation, Call of Duty. Although the original game in the series ran off the id Tech 3 engine, for the highly regarded Call of Duty 2 the developer built its own in-house middleware which, until recently, had no official name. When questioned at E3 this year, however, we were told by an Infinity Ward rep that the upcoming Modern Warfare 2 would be running on the IW 4.0 engine, a generation beyond what we saw in the so-spectacular-it-hasn't-aged-a-bit Call of Duty 4, released in 2007.

If you've played that game, then the quality of the engine and the experience it can deliver needs no introduction. Phenomenal animations and lighting lead the way, although its ability to handle complex A.I., amazing sound, depth of field and dynamic bullet penetration - all at a blistering pace - cannot be ignored. Better still, it runs a beauty over a network, leading Call of Duty to be one of the most successful online experiences of all time. The engine enhancements for Modern Warfare 2 are subtle, but powerful. A new streaming texture technique allows the world's objects to appear in far greater detail and resolution, while there have also been major improvements to the lighting, physics and A.I.
