Some games pit players against zombies. Some feature monsters. Still others go toe-to-metal-toe with robots. EnMasse Entertainment's Zombies Monsters Robots has all three. EnMasse announced the game at this year's GDC, revealing it to be a free-to-play third-person shooter and spiritual successor to iOS shooter Mercenary Ops. Unlike Mercenary Ops however, ZMR will be coming to PC, with Steam Early Access starting in May.

In ZMR, portals have opened into alternate dimensions, unleashing zombies, monsters and, yes, robots. Up to eight players band together to stop the advancing hordes across multiple game modes, including a campaign and wave-based survival. Alternatively, if you can't - or don't want to - beat 'em, join 'em by playing competitively; the game also features a 16-player head-to-head mode where teams are split into monsters vs. humans.

Polygon reports that EnMasse plans to roll out extra content after the game is launched, including "Dino Island" DLC which features an map inhabited by dinosaurs with guns on their backs. Screenshots released for the game show off plenty of other baddies as well, so place your bets on which creature will be your undoing. Personally, we vote death by merman.
