Basically it seems to be Minecraft then actually playing on the map with guns and such in what appears to be Capture the Flag and Deathmatch. I think this could prove quite interesting and it reminds me of Ace of Spades (a game like this but is less quality)

I suggest signing up for the Beta very quickly.
