    Drop in, drop out...

    Cooperative carnage

    Gather together Earth’s steeliest soldiers and prepare to make bloody mulch out of invading alien forces as you take back the planet.

    The fight is out there: drop in as soon as you’re suited up and join with up to three other players as they face down staggering odds. Or, when the heat is on, call on others to back you up and help drive away the extra-terrestrial hordes.

    Combine the most brutal firepower and the deadliest tactics to secure victory. Flank forces and target weak points to create strategic advantages or simply go shoulder to shoulder and let rip a devastating ballistic tidal wave – this is your war soldier, fight it your way.

    Highly-trained specialists…

    Choose your class

    All things great and small…


    Harness the terrifying power of biological warfare to rain chaos onto the battlefield. The Bio-Specialist’s high-tech armour operates like a mobile laboratory, allowing you to release swarms of nano-machines to suffocate oncoming enemies or race to the aid of injured teammates.

    With the power to leech health from the xeno hordes and douse the battlefield in poisonous clouds, the Bio-Specialist is a modern master of the dark arts.  

    Bring on the muscle…


    Send shockwaves through the battlefield with devastating physical attacks and colossal firepower. The Exoskeleton’s heavy-duty armour plating proves that a great defence is sometimes the best form of attack. Plough through your enemies like a battering ram with a power-assisted dash or send tremors rippling through your enemies with a devastating “ground slam”.

    Like a tank on two legs, The Exoskeleton packs not only enormous artillery, but enough bravado to put even the Xenos off their guard. 


    Now you see me…


    Bend the very light around to slip unseen across the battlefield and execute your enemies with cunning and stealth. The Saboteur can also call down devastating airstrikes, slice through enemies with his deadly laser sword, or vanish from sight completely and sneak past unseen.

    Dealing death with lightning speed and lethal, focused attacks, the Saboteur is a ninja assassin for the new generation.
