Endgame takes you into a war zone. Choose a mode from a set: battle royale, team games, survival, classic battle. Basically, you have to choose between playing solo or playing as part of a squad. With any choice you will have to rely only on yourself. Comrades can cover from the rear, but not always. Move with caution, a bullet can come from anywhere and you may not see the shooter, so try to avoid open areas where you could become an easy target. When you see an enemy, shoot quickly in Endgame.
