Two former Army Rangers, Tyson Rios and Elliot Salem, join a Private Military Corporation called SSC, taking on missions across Afghanistan and China. As they progress through their work, they begin to question the true nature of their job.
Army of Two focuses on cooperative gameplay, where two players team up to complete objectives and take down enemies. The game features a wide range of customizable weapons, including pistols, shotguns, and sniper rifles, which can be modified with various attachments. Players work together to overcome challenges, such as lifting each other up ledges, healing, and covering each other's backs.
The multiplayer mode supports four players, divided into two teams, and features three game modes: Warzone, Bounties, and Extraction. Players must complete objectives while fighting against the opposing team, adding a new layer of strategy to the cooperative gameplay.
