Free-flowing traversal gunplay allows the player to engage in combat from any position in the environment even while climbing and hanging. Competitive multiplayer gameplay includes up to 10 players in heroes-versus-villains matches or up to three players can work together in cooperative modes to accomplish set objectives with increasing difficulty and against special enemy characters.
