Only just yesterday I began playing this game, and I'm really enjoying it. It's, as the GB page states, a PVP focused game similar to Minecraft or Terraria. You're construction options are much more limited than those games, but if expanded, the game would become unwieldy. Like those games, you gather materials and build. KAG has your team building fortifications to protect your base and attack your foe's. The mining can also be offensive, and you can dig up into their base. The building aspect really enhances the game, and I find it more entertaining than older 2D PVP games like Gang Garrison because of the Minecraftiness. It's a really fun little game, and there are a good number of people playing. It's free, so check it out.

I'm BoG in the game, if you ever play.

I just found out about this game. I'm going to download it and play it as soon as possible! Sounds really fun, I really like Soldat!

@Demokk: What's your name in the game? We should totally play some time.
