Ace of Spades delivers building, block-blasting FPS gameplay to Steam this Dec.

Voxel shooter Ace of Spades has been around in prototype form for some time now. The game, which has been compared to Minecraft due to its crafting and building systems (also, those visuals), already has an install base of half a million users according to developer Jagex.

That number may very well grow now that the game is headed to Steam. You'll be able to build forts and blast enemies in this intriguing new FPS  endeavor sometime in December.

Ace of Spades looks to deliver a different kind of FPS experience. Suffice it to say that whether you're a fan of traditional shooters looking for something new or just a diehard indie gamer, you should definitely watch out for this one.
