maps look good and the game is a lot smoother, but i think the mw2 maps were better developed, theres a few points on mw3 where i should be able to jump over but cant, gets annoying when your tryin to get away and it blocks you.
other than that i quite enjoy it, gettin used to the weapons, thank god quick scoping has gone and the grenades arent as powerful, but my weapon of choice for mw2 (scar) isnt as good on mw3, makes you use more guns.
also knifing isnt as bad as on mw2, no lunge.
elite seems like a big waste of money tho
