Keen Software House's in-development 6DoF action game Miner Wars 2081 is now in closed beta, and its developers have released the video above showcasing a four-player cooperative mission.

Similar to the classic Descent, Miner Wars is a "first-person action-survival space simulation game" that gives players six-degree control over a spacefaring vessel that must scavenge for fuel, weapons, and other necessities in a series of destructible, open-world environments. Keen Software House has previously released the spinoff title Miner Wars Arena, and an online version, Miner Wars MMO, is also in development.

The alpha version of Miner Wars 2081 can be purchased for $39.99 at Desura.
