Battlefield 4 is a firest person shooter video game developed by Swedish video game developer EA Digital Illusions CE (DICE) and published by Electronic Arts. It is a sequel to 2011's Battlefield 3. It was released on October 29, 2013 in North America, October 31, 2013 in Australia, November 1, 2013 in Europe and New Zealand and November 7, 2013 in Japan for Microsoft Windows,PlayStation 3, PlayStation 4, Xbox 360 and Xbox One.
The game's heads-up display (HUD) is much the same, composed of two compact rectangles. The lower left-hand corner features a mini-map and compass for navigation, and a simplified objective notice above it; the lower right includes a compact ammo counter and health meter. The mini-map, as well as the main game screen, shows symbols marking three kinds of entities: blue for allies, green for squadmates, and red/orange for enemies.
Players can use dual-scoped weapons, including weapons with different firing modes (e.g. single shots, automatic fire). They can "spot" targets—marking their positions to the player's squad—in the single player campaign (a first in the Battlefield franchise) as well as in multiplayer, allowing teammates to either suppress or eliminate them. Bullet-dropping-system has become much more enhanced allowing players to precise their aiming with the environment. In addition, players will have more survival capabilities, such as countering melee attacks from the front while standing or crouching, shooting with their sidearm while swimming, and diving underwater to avoid enemy detection.
The single-player Campaign has several differences from the main Multiplayer component. For the most part, the player must traverse mini-sandbox-style levels, in some cases using vehicles, like tanks and boats, to traverse the environment. As the player character, Recker, the player can use two Campaign-only functions: the Engage command and the tactical visor. The Engage command directs Recker's squadmates, and occasionally other friendly units, to attack any hostiles in Recker's line of sight. The tactical visor is a special binocular-esque gadget that allows the player to identify friendly and enemy units, weapon stashes, explosives, and objectives in the field. By identifying enemies, the player can make them visible without using the visor, making them easier to mark for their teammates. At one point, Recker will briefly lose the tactical visor, forcing them to only use the Engage command to direct his squadmates on a limited number of enemies.
