It's completely cooperative, with your opponents controlled by an A.I. who wants one thing: you, dead. Your team consists of three player-controlled heroes -- players can choose from the Space Marine, the Ork, and the Eldar -- whose sole task is to fight against wave after wave of increasingly difficult enemy forces. With little downtime between waves, players have to do their damnedest to keep their multiplier up, so as to ensure a high score and earn experience to level their characters. And to get a higher multiplier players have to control various map points, defeat sequential waves with no casualties, or kill all the enemies in a wave within a preset amount of time.

That probably sounds like a lot, but in practice The Last Stand amounts to killing everything you see. And even if you die or don't hold the control points, your team can up your score simply by surviving. After all, since score and experience are the main reason you're playing, you never really lose, but instead just gain levels and win new pieces of gear to use in subsequent battles. So even in defeat you're rewarded. The result (if you have teammates you get along with) is a desire to jump right back into the fight again and again in order to level your character, equip new items, and get just a little bit further than before.
