The three StarCraft II mods unveiled at last year’s BlizzCon are now available for beta testing. Although Blizzard hasn’t yet announced a release date for Left 2 Die, StarJeweled and Aiur Chef, you can test out all three by booting up StarCraft II and checking out the custom games window under the Multiplayer tab.
If you aren’t familiar with the games from the BlizzCon announcement, Left 2 Die is co-op survival type game (kind of like Left 4 Dead!) that has the player fighting off squad after squad of Terrans until inevitable death. StarJeweled lets you bombard your opponent provided you can match up similarly-colored shiny gems. Finally, Aiur Chef lets the player search the map for ingredients used to complete meal recipes.
