I sure some of you guys already know that ace of spades is a voxel game, well here is a preview of one which is on another level.

it's called Lords of Uberdark It may look similar to minecraft but if you read the bottom link the developer states that his main goal is to make a "team based" game with "first person combat" and a minecraft building aspect. sounds familar....
