Blizzard Entertainment announced the beta testing of three new custom maps created by the developers. The official release date is not determined, but you can play it right now to test and submit bug reports and feedback. You can download the three maps here.

Aiur Chef
Category: Collection/Cooking
Mode: Free For All
Players: Up to 8

Each round of Aiur Chef features a theme ingredient and three succulent recipes that play upon its unique flavor. Before you can master these themed dishes, though, you’ll first need to scout across the map and collect a variety of tasty ingredients (including the theme ingredient). Each recipe has its own set of required ingredients, listed in the recipe menu in the upper-left of your screen, which can be picked up off the ground or acquired by killing specific creatures. Don’t get too greedy when loading up on ingredients, though — inventory space is limited, so you’ll want to focus on collecting ingredients for one recipe at a time.

StarJeweled
Category: Puzzle/Strategy
Mode: Solo vs. A.I., Co-op vs. A.I., Player vs. Player
Players: Up to 4 (1v1, 1v1 A.I., 1v2 A.I., 1v2, 2v2, 2v2 A.I., etc.)

StarJeweled focuses on matching groups of jewels according to color and strategically selecting StarCraft II units to overcome an opponent’s forces and destroy their base. StarJeweled can be played several ways, including cooperatively against the A.I. or competitively against other players.

Left 2 Die
Category: Survival and Siege
Mode: Co-op, Night 2 Die
Players: Up to 2

Left 2 Die is a cooperative take on the StarCraft II: Wings of Liberty campaign mission Outbreak that shifts between two phases: a night phase and a day phase.
