Call of Duty: Modern Warfare 3 (Also reffered to as MW3, COD8, COD: MW3) is a first person shooter developed by Sledgehammer Games and Infinity Ward. The game is based on a class system where the player can select various primary weapons including assault rifles, submachine guns, machine guns, shotguns, sniper rifles, and riot sheilds. There are also secondaries, which include launchers, pistols, and machine pistols. Weapons can have "proficiencies" which can enhance the weapon or your person. Equipment and special grenades are also available, which vary from tactical insertions to semtex and concussion to emp grenades respectively. There are 3 perk slots that all have various perks that can aid you in the game. The perks can be improved while using them to become "pro" perks that include added benefits. Deathstreaks and pointstreaks give either an improvement to your person if you die enough times, or give you something to use for your benefit for killing people or accomplishing objectives. Pointstreaks come in 3 "packages," support, specialist, and assault. Assault is the regular setup where if you die, it resets, but the rewards usually come at lower streaks and they can be reset. Support does not reset if you die, but is more team oriented and doesn't affect your enemies as much. Specialist gives you another perk at 2 kills, 1 more at 4 kills, another at 6 kills, and every specialist perk (every perk except overkill) until you die.
