Express. is it posible to have a 17 way intersection of only 4 routes? Yes, yes it is.
Drone. Fun to look around in. reminds me of Lost. Also reminds me of a corn maze made out of building.
Plaza. I really dig the sexy tunes in that one bar, but the map is not good for HQ. See above re: maze.
Hijacked. fun TDM, but, there is a make or break HQ location in a tight game. We usually lose on that one base alone.
Overflow. Made by some MW3 fanboy for sure. Good TDM, but sht HQ map. First base, expect to go 2-18 getting just the ONE, even with FJ and Tac Mask...Trophy and all the training wheels. it's a poachers paradise.
That leaves 9 that are either tolerable, or completely lovable.
No bad, considering I hate nearly every MW3 map.
