Crossfire is a large open level with a fair amount of places to hide and camp. Due to this it's good for Domination matches and Hardcore Team Deathmatches. Crossfire has a lot of close range battles which enables the use for shotguns and the Assault class. Snipers can also be found on the map.
Always make sure you are hiding somewhere. Since this level is mostly open space, you will most likely be a sitting duck for your opponents gunfire.
