Introduced in Battlefield 3, a Battle Pickup is a firearm (special or not) located at a certain location within a map, differing from the weapons normally chosen by a player depending on their kit. Battle Pickups are reminiscent of Doom and other early FPS games that required players to search for weapons and valuable items.
The Aftermath expansion pack for Battlefield 3 introduced Scavenger mode, where players equipped only with handguns and grenades had to find more powerful weapons—chosen from a preset pool of infantry primary weapons—scattered around the battle area. Although not referred to as "Battle Pickups", these would lay a foundation for including weapons that are not carried into battle by players.
Battle Pickups are introduced in Battlefield 4. These are weapons that DICE wished to include in the game, but could not suitably balance for multiplayer gameplay. As such, only limited numbers of these weapons are available to all players, and must be picked up from gun cases located somewhere on the map. Battle Pickups are marked with a white star icon via 3D spotting (minimap and first-person view).
Aside from the USAS-12, Battle Pickups come with a limited supply of ammunition that cannot be replenished from ammo boxes. Players carrying a battle pickup retain all of their kit equipment. However, the battle pickup will be dropped if the player switches to another weapon or gadget. The battle pickup can then be picked up again from the location where it was dropped if it still contains ammo.
After the weapon's ammunition is depleted, or some time has passed after it has been dropped, the Battle Pickup will respawn at its original location. Battle Pickups will not be dropped in water or when entering vehicles. All Battle Pickups in all their variations can be found in front of the firing range on the Test Range. Players with custom Emblems will automatically have them fixed to any weapons once picked up.
Battle Pickups are featured in Battlefield Hardline.
