Title's obvious where they got inspiration from, but it tends towards modern shooters rather than placing the emphasis on the voxels. The technology however lends players the ability to completely destroy anything with their guns. You can even use helicopters to blow everything into oblivion. I'm not sure if tanks will ever make their way in, though I *think* they've mentioned it somewhere that they're considering it.
Surprisingly, I didn't feel like this was much of a Minecraft mod, and thought the overall concept was really quite cool. My other concern was that this will be MP only, but the developers have plans for a singleplayer campaign too. I hope they go through with that.
There are a few gameplay videos that you guys can check out.
The funding's over, but I just asked the developers if they have any plans to let players continue to pre-order this during its alpha and beta phases. I'm still waiting for their reply.
