Crossfire is a multiplayer map in Call of Duty 4: Modern Warfare, it also appears in Call of Duty: Online, with perhaps the most open buildings. It is a favorite of snipers. Intense sniper battles often occur between the two two-story buildings at either end of middle street. Plenty of combat also occurs in the small buildings that line the middle street. Crossfire is good for Domination matches and Hardcore Team Deathmatches, as there are lots of spots. Assault and sniper classes work well on this map. Shotguns are also a popular choice to do the large percentage of close-range fighting.
