ohhhh looks like your not "#winning" today sir, thats been there since the release ;P its the name of the engine they use since CoD 2 called "id Tech 3" (came out in 1999) obviously referring to the 3, do some research guys before posting these questions, please and thank you.

ON the mw2 edition xbox the same symbol is on the back but with a 4 instead of a 3

Kingkinght60 wrote It's the version of the IW engine used. And Ambicidal, the IW is i guess the same in its core but each game has a new version, either a new version like itunes goes from 10 to 11 but its new right? where as cod4 to cod5 was like itunes 10 to 10.1, just a small change

basically im pretty sure MW2 has a 4 somewhere on the menu

ImJustEpic1 wrote Its the same engine but when they upgrade all aspects of the enige it becomes 2.0 3.0 4.0 and so on. Its like with Battlefield 3 Their frostbite 2.0 engine is Frosbite 1.0 but all major aspects are upgraded or better.

HeyPerson wrote The 3 in IW3 Means it is the 3rd call of duty game made by IW

IW did not make COD 3. Treyarch did.

COD Classic: IW
COD 2: IW2
COD 4: IW3
MW2: IW4
MW3: IW5

efextra wrote It's the engine number, how do I know? I have all Call of Duty games on my PC and cod4 is iw3sp/iw3mp and MW2 is iw4sp/iw4mp It's what infinity ward keeps count on how many games they make also too.

You are correct as the mw3 engine is IW5 and it is the 5th CoD made by IW
