Ace of Spades is a multiplayer first-person shooter game with a similar 'blocky' environment to MineCraft. The goal is simple: Capture the enemy intel and bring it back to your base. The teams are blue and green, the blue team starts in a very hilly region and the greens begin in a flat region. A river usually separates the two. The game has a very World War One feel to it as people build trenches and forts to defend their precious intel.
