About this game:
Miner Wars 2081 is a 6DOF action-survival space-shooter simulation-game set in the year 2081, 10 years after the destruction of all planetary objects in the Solar System.
You operate an advanced mining ship in a fully destructible and open-world environment, which remains persistent as you complete missions or play online with others. Realism and survival are key aspects of gameplay. Inventory and the way you use resources such as fuel, ammunition, oxygen, ore, and weapons are important when surrounded by dozens of warring factions.

Do note its an unguaranteed key, I just know what it is because I already own it.
