MW2 dum,dum. :(
Im pretty sure Mw2 is better because i have both and mw2 has a better multiplayer. Mw2- 9 out of 10 Cod4- 8.5 out of 10
mw2
no, mw2 was made by infinity ward
MW2 has a much better rating i think that there is much more action in it. i only played MW2 and Bo (black ops) demo but i know MW2 is better
kill 5 enemies with cooked grenades they don't have to be held in your hand and blow up. you just have to hold it for until the cursor changes then throw
there is no g3 in the game there is one in COD4 not MW2
