Ace of Spades: Minecraft with Guns
Well, not really, but it's a quick description that suits the game well. Ace of Spades is an open world, team-based, CTF shooter with building elements. You can dig and build fortresses as you attempt to dominate the terrain and steal the enemies briefcase. The building part of AoS is rudimentary as compared to Minecraft's expansive setup, there is no crafting so you can't make better guns by finding rare elements - at least yet. AoS is in beta so work is still progressing.
