Publisher En Masse wants you to “kill everything” in its free-to-play third-person shooter, Zombies Monsters Robots. To make this as exciting as possible, it will be releasing a significant update on Tuesday. Entitled Mummy See Mummy Doom, the update includes new maps, weapons, and a new game mode. “Whole cities in China and Egypt have been overtaken and transformed into nightmarish versions of ancient worlds, teeming with hordes of undead horrors,” the publisher states.

Along with six new maps, the game is getting Blood Diamonds mode. In the competitive mode, you fight against other players to collect diamonds, which drop from dead bodies.

If you want to know more about the game, you can check out our preview here. It’s available on PC and you can download it for free at the Zombies Monsters Robots website. Furthermore, as you might have already noticed below, we’ve teamed up with En Masse to offer 15,000 GameSpot readers a free in-game weapon. The M1932 semi-automatic handgun equips in the sidearm slot and, we’re told, is great for putting an end to zombies, monsters, and robots that get a little too close for comfort.
