When I play MW3 I notice Something in the maps. There is two entrances across the map on opposite sides, and one open area in the middle. Raven software, really? Ive made better maps In Farcry 2.

In Crossfire you have freedom to go wherever you want but in Resistance you can only go across the map in those three spots and they are death traps if the enemy is holding them down.
