Rockstar has announced a new mode for Grand Theft Auto Online, the 'Every Bullet Counts' Adversary Mode that's a Last Man Standing variant with a "unique twist" that aims to keep players constantly on-edge and on their guard. There's simply no place to hide, and campers will be punished in kind. It sounds incredibly tense.The idea behind Every Bullet Counts involves four players competing against one another in a confined area with just one marksman pistol and two bullets to take out three rivals. That means tactics are vital, as once your two bullets are gone, you'll be forced to adopt sneaky melee attacks with a hatchet or machete to get out alive.Anyone stupid enough to camp, meanwhile, will have their position revealed with a blip on the map, making them an easy target for enemies to track down and murderise. Every Bullet Counts also takes place at new GTA Online locations such as the De Santa family mansion in Rockford Hills and the Tequi-la-la nightclub.The Every Bullet Counts Adversary Mode is available now in GTA Online for Xbox One, PS4 and PC, with a Featured Playlist enabling players to participate in all four of the new maps associated with the mode in quick succession with just a single button press during the GTA V launch/loading screens.
