War comes home in Call Of Duty: Modern Warfare 3, the explosive third chapter of the blockbuster first-person action series set in near-future combat scenarios. Like its predecessors, Modern Warfare 3 is a first-person shooter video game. Activision confirmed at Gamescom 2011, that Modern Warfare 3 on the PC has dedicated servers support.

Campaign
The player assumes the role of various characters during the single-player campaign, changing perspectives throughout the progression of the story. Unlike its predecessors, the campaign is spread over different days. Each mission features a series of objectives that are displayed on the heads up display, which marks the direction and distance towards and from such objectives. Damage to the player is shown by blood splatter shown on the screen. The player's health regenerates as time passes. Objectives vary in their requirements, ranging from having the player arrive at a particular checkpoint, to eliminating enemies in a specified location, to standing their ground against enemy squadrons, and planting explosive charges on an enemy installation. The player is also accompanied by fellow soldiers who cannot be issued orders.

Multiplayer
The entire Killstreak reward system has been revamped. Killstreaks are now known as Pointstreaks, and kills are no longer the only way to increase the player's pointstreak. Completing objectives such as planting the bomb in Search and Destroy or capturing a flag in Capture The Flag awards points towards the player's Pointstreak. Pointstreak rewards are organized into three different "strike packages" called Assault, Support, and Specialist. The Assault strike package works the same as the Killstreak reward system in Modern Warfare 2 and Black Ops, offering rewards like the Predator drone and attack helicopters. The Support strike package offers support-style rewards, such as UAVs and SAM Turrets. Rewards from the Support category do not reset when the player dies, but accumulate over the course of a match. The Specialist strike package rewards players with perks of their choosing after every second consecutive kill. After eight kills, they receive every perk in the game, but reset back to none upon death. Players are allowed to choose which Pointstreak rewards they want to use when they gain it during the match, rather than choosing them between rounds.
