Over three months after Blizzard announced and showed off four of its special custom maps for its sci-fi RTS game StarCraft II, during BlizzCon, three of them are now available for players of the game to try out via a beta test. Players can find the maps by heading to the Multiplayer tab in StarCraft II and find the maps in the custom games window.

One of the maps is Left 2 Die, based (sort of) on Valve's Left 4 Dead zombie shooter as players take out infected structures during the day and build defenses to deal with the Zerg infestation at night. There's also a survival-like mode in the map called Endless Night where daylight never comes and players must fight off wave after wave of Zergs.

Another map is Starjeweled which takes its inspiration from PopCap's best selling puzzle game Bejeweled. Puzzle solving becoming the key to training your troops and taking out enemies in this map. Finally there's Aiur Chef, where players must try to collect components on the map to make meals based on one main ingredient (in a nod to the Iron Chef TV show). The fourth custom map shown at BlizzCon, Blizzard DOTA, is not yet available for beta testing.
