Battlefield 3 is the direct sequel to 2005's 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.
