The two factions fight differently: as a Mantel soldier the player has the option of using Nectar, thus making targeting and aiming more precise and powering the player's melee attacks. After realizing that the Mantel army's goal of achieving peace is only a lie fed to the brainwashed soldiers, the player has different fighting abilities among the rebels, like playing dead, laying grenade traps and being able to cause Nectar overdoses on Mantel troops. These overdoses make the soldiers berserk, disorientate them and make them unable to distinguish friend from foe.
The single-player campaign also features a cooperative option to play along with three friends. The multi-player features deathmatch, team deathmatch and an objective based assault mode.
