Just got mw3; 3 days ago, i cant play online cuz of lag atm (free hotspot because i"m working at mountain lol) but i did 20% of solo mod and i tryed 2 maps in multi (i did not lagged a lot because used wifi of work). Well anyway, this is so insane, i mean i run it in ultra on my laptop, graphism are so cool , campaign is nice too. About multi i can say much because it was my first COD multi game, i felt noob... better stick to ET for multi. Maybe it's stupid to buy it only for solo but i ll try harder online when i ll get better connection.
