I've found something called Ace of Spades, a game where you dig blocks, build with blocks, shoot with guns, and try to capture the flag, uh, intel. You can throw up some cover in seconds, or spend more time to build large fortifications or sniper towers. Despite the blocky graphics, the combat feels very realistic, with deadly guns, recoil, limited ammo and so on.

Remember to change your name in the config file so you're not just another deuce.
