Miner Wars is a 6DOF underground and space shooter played in a fully destructible environment and is a combination of single player story game and MMO.

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.

By the way, if you want in the closed beta you have to get 250 clicks from people.

If you guys didn't know you can go on the downloads section on the minerwars sight and download the benchmark demo, it's basically the client you will be using to play except it has about 6 different scenarios where it takes you ingame and your controlled by an AI just to see if you can handle it.
