Bach, in an interview with Game Informer, said DICE evaluated the controls for Battlefield 4 and made some modifications from Battlefield 3 to improve communication and put an emphasis on team play.
“We wanted players to be familiar with using spotting and the communication rose in multiplayer as well as the engage and tactical visor in single player," Bach said.
With the goal to “highlight one of Battlefield’s key strengths,” DICE changed the button configuration so that team play functions would be on the bumper button, which in turn required the Battlefield 4 developer to make some other changes.
“To accomplish this (highlighting team play) we needed a button that allowed players quick access while also enabling the player to still perform all the necessary functions of Battlefield, like shooting, aiming, moving, and melee,” Bach said.
Bach said the default layouts have been designed to be accessible for novices, “while keeping team play and social features close at hand.”
DICE will over a “veteran” scheme for Battlefield 4 that all but reverts the button configuration back to that of Battlefield 3, though the communications rose will still be connected with the right bumper.
Battlefield 4 hits shelves tomorrow for PC, Xbox 360, and the PlayStation 3. Next-gen versions of the game will launch with the Xbox One on Nov. 22 and the PS4 on Nov. 15 in North America and Nov. 29 in Europe.
