Battlefield 3 is the direct sequel to Battlefield 2 and is the 11th overall entry in the Battlefield franchise. Powered by the Frostbite 2 engine, Battlefield 3 aims to provide the fast-paced, team-oriented online multiplayer the series has made its name upon while also providing the first true single-player campaign in a numbered Battlefield game, and for the first time in any Battlefield game numbered or not is a cooperative mode. The game also introduces the Battlelog feature, an in-browser service which gives in-depth statistics for individual soldiers such as their Win/Lose ratio, their favourite weapon, how accurate they are - and so forth. Battlelog also allows players to create Platoons which are not unlike clans which track the stats of a combined group, allows for scrimmaging, voice communications, and parties which will attempt to bundle friends and platoon members into squads together if possible. The game is also launched from Battlelog although settings are altered in-game.
The campaign is set in 2014, where players take on the role of Staff Sergeant Henry Blackburn and occasionally other members of his 5-man squad. For the majority of the story, Blackburn is being interrogated about knowledge of an attack on New York and as such the missions take place in a disjointed, flashback fashion as Blackburn recounts his encounter with the PLR - a dangerous terrorist organization who may be after chemical and nuclear weapons. The campaign plays like most other shooters, as the player uses various weapons to dispatch enemies and push to the end of each scenario often aided with AI companions. The campaign does offer some variety though, occasionally allowing the player to ride inside tanks, jets, and helicopters - but unlike multiplayer, it is rare that the player gets a chance to actually drive these vehicles. The multiplayer suite contains Conquest, Rush, Team Deathmatch, and Squad-based variations of Rush and Deathmatch. Like in past Battlefield games, there are multiple classes. The Assault class uses assault rifles and carries medic kits and defibrillators to heal and revive teammates, respectively. The Support class uses light machine guns and carry Ammo packs to resupply teammates and C4 which can be used to destroy tanks or crumble buildings. The Engineer class uses sub-machine guns, has a blow torch for repairing vehicles and a rocket launcher for destroying them. Lastly, the Recon class carries long-range rifles and uses motion detectors and mobile spawn points to detect enemies and allow friendlies to spawn anywhere on the map. All classes can unlock new gadgets and specializations, each weapon also has an unlock tree that unlocks weapon-specific items based on how often and how well that particular weapon has been used.
Console editions of Battlefield 3 support a lower amount of players and smaller maps. Only 24 players can meet up online in the Console iterations. The PC version also only supports Windows Vista or Windows 7, as it cannot run without a DirectX 10 or 11 card.
