Keen Software House has released an alpha demo of Miner Wars 2081, an action single/multi-player underground-and-space shooter played in a fully destructible environment. In Miner Wars 2081, as a player, you operate an advanced mining ship in an open world asteroid belt area. You dig kilometers of tunnels, harvest the ore, travel the solar system, fight your enemies and discover mysterious alien secrets. The story will introduce you to many types of missions: rescue, exploration, revenge, base defense, theft, transportation, stealth, search and destroy, pure harvesting, racing or just flying around and destroying everything you see. Miner Wars 2081 will be available later this year for PC, Xbox 360 and iPhone.
