The player has access to a wide range of weapons, including handguns, rifles, submachine guns, a shotgun, rocket launchers, combat knives, grenade launchers, various explosives, and several extraterrestrial weapons.[7] Further weapons are unlocked during the training activities in the hub.[1] Almost all of the weapons in the game have two modes of fire: a primary mode in which the weapon is used in a typical fashion, and a secondary mode which uses the guns in other ways, such as them being close-quarters melee weapons.[7] Players can carry an unlimited number of weapons, and certain guns can be used in duplicate, one in each hand.[8] Most weapons have a finite magazine and must be reloaded after a certain number of shots. Interaction with objects in the environment is via a single "Use" command.[6] Enemies and players can disarm each other at close range, and the player can use this feature to steal weapons or knock foes unconscious.[6][9] Damage taken during combat for the player and enemy units is location-based, with a shot to the torso causing more damage than a shot to a limb.[6][9]
