Battlefield 4 (BF4) Gameplay Kunlun Mountains Mission Five
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 binocular. The Engage command directs Recker's squadmates, and occasionally other friendly units, to attack any hostiles in Recker's line of sight. The tactical binocular is similar to a laser-designator, in the sense that it 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.
The campaign features assignments that require specific actions and unlock weapons for use in multiplayer upon completion. Collectible weapons return along with the introduction of collectible dog tags which can be used in multiplayer. Weapon crates are found throughout all levels, allowing players to obtain ammo and switch weapons. While crates hold default weapons, collectible weapons may be used whenever they are acquired and level-specific weapons may be used once a specific mission assignment has been completed by obtaining enough points in a level.
