This is worth a look.
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 deep secrets.
Game play is led by an epic story and is a combination of a single/multi-player game, cooperative, or you against everyone.
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.
Platform: Windows, Xbox 360 Live Arcade
The Game is due for release Late 2010. For a limited time you can purchase - and play throughout the Alphas and Betas - and get the final release also - for 70% off the final price.
Visit Miner Wars - there is a lot of info on the site already... I'm downloading the game right now.
