Call of Duty 4

Call of Duty 4: Modern Warfare is a first-person shooter video game, developed by Infinity Ward and published by Activision.
Call of Duty 4 features team-based and deathmatch-based multiplayer modes on various maps. Each mode has an objective that requires unique strategies to complete. Players can call in UAV reconnaissance scans, air strikes, and attack helicopters, either an AH-1 Cobra for S.A.S. or USMC or an Mil Mi-24 for OpFor or Spetsnaz, when they achieve three-, five-, and seven-enemy kill streaks respectively.
