Recently there are two entries with the theme of FPS style blocks in Minecraft.
Two games somewhat different, both in fighting style (one to be more dynamic) as having very different classes and weapons.
Would now be two new games, which would compare with the war between Battlefield and Call of Duty? For these games, although they are different in many points, have the same idea.

The two games are very good, one is still in beta (Guncraft) it also gives the option of putting your map minecraft to play the game (provided buy the pre-release) and the other (Ace of Spades) has gone to the beta, is in steam.
