...:::> Call of Duty 4 Multiplayer Synopsis
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. A game ends when either a team has reached a predefined number of points, or the allotted time expires in which case the team with the most points wins. However in the rare case the points are even when the time expires, Sudden Death mode is activated in which there is no re-spawning and the team who either has the last man standing, or achieves the objective first are the winners.
Completing a challenge grants experience points and may unlock weapon attachments. When a player's level increases, it may unlock new weapons, perks, or challenges. At lower experience levels, the player only has access to five pre-determined classes, and cannot create a custom class with the weapon of their choosing. However, as the player advances in levels, they earn the ability to customize their classes. This includes selecting their main weapon, side arm, and special grenade type. Additionally, the player can select a limited number of "perks" that can customize their character further. Perk effects include increasing damage by the player, being able to take more damage, or dropping a live grenade after being killed in an act of martyrdom. The player is also given challenges to attempt, including achieving a certain number of kills with a specific weapon or shooting down a helicopter or performing a number of head shots.
