We're sure you watched thousands of YouTube videos last year, but we bet only a handful featured flying robots with guns, and just one of those was an explosive multiplayer mech battle built on Unreal Engine 3 -- yeah, that one, right up there. Hawken, the breakout title from indie studio Adhesive Games, is scheduled to launch on Dec. 12, published by Meteor Entertainment.

Hawken will be web-based, free-to-play and feature fast-paced action in short bursts, styled after Call of Duty multiplayer, Adhesive co-founder Khang Le said. Players in Hawken will battle for survival and resources inside flying, rocket-equipped mechs in various regions of a barren industrial wasteland (or heaven, as we call it). Hawken is multiplayer only and will play in a session-based format similar to League of Legends, Le said.

For a further glimpse at Hawken's universe, hit up the video after the break, which displays desert gameplay. If that intrigues you, sign up for the closed beta right here -- get three friends (enemies, strangers) to enlist and guarantee your spot.
