Blackmail wrote More than half the guns in MW3 are copied from Battlefield 3. And don't even say they weren't because BF3 was released in October and MW3 was released in November.

Some examples:
PKP
PP19
MP7


Just another reason why MW3 sucks.

There was a month difference between the two. MW3 wouldnt have allowed people to goto elite and the bf3 guns were there. You must be an epic genius if you think they would JUST then put in the guns...
