Battlefield 3 is a first-person shooter video game developed by EA Digital Illusions CE and published by Electronic Arts. It is a direct sequel to 2005’s Battlefield 2, and the eleventh installment in the Battlefield franchise.

In Battlefield 3‍ ’s campaign, players take on the personas of several military roles: a U.S. Marine, an F-18 weapons system officer, an M1A2 Abrams tank operator, and a Spetsnaz GRU operative. The campaign takes place in various locations, including Iran to New York City; and follows the stories of Sergeant Henry Blackburn and Dimitri Mayakovsky.

Battlefield 3 features the combined arms battles across single-player, co-operative and multiplayer modes. Battlefield 3‍ ’s multiplayer matches lets players take on one of four roles: Assault, Support, Engineer and Recon. The Assault class focuses on assault rifles and healing teammates. The Support class focuses on light machine guns and supplying ammunition.

The Engineer class focuses on supporting and destroying vehicles. The Recon class focuses on sniping and spotting enemies. The mechanics of the weapons have been changed to utilize the new engine: compatible weapons may have bipods attached which can then be deployed when in the prone position or near suitable scenery, and provide a significant boost to accuracy and recoil reduction. Suppressive fire from weapons blurs the vision and reduces the accuracy of those under fire, as well as health regeneration.
