Infinity Ward’s Robert Bowling has revealed that while the same game engine will be used for Modern Warfare 3 it will be different.
Posting on his Fourzerotwo twitter account Bowling said “We haven’t gone into detail on the engine yet but we’ve moved beyond the MW2 engine and added a lot of cool stuff for #MW3.”
Hopefully they don’t go down the route of gimmicky elements that are fun at first but will eventually be boring and go for something more substantial. Fingers crossed we will find out more at E3.
