Blizzard has announced the release of three new official StarCraft II mods: Aiur Chef, Left 2 Die, and StarJeweled.

The mods have previously been available in beta form, but Blizzard says the final release versions have been "polished with improvements and bug fixes, plus they now feature official achievements complete with brand-new avatars to unlock".

StarJeweled: Pit your puzzle-solving talents against your opponent's. Match jewels to generate resources - and spend them to attack with StarCraft II units, countering your adversary's forces and destroying their base.

Aiur Chef: Gather and mix exotic ingredients in a cooking race against your opponents. Choose your recipes carefully to achieve culinary dominance and be counted among the most hallowed chefs of Aiur!

Left 2 Die: Working together with a partner, defend your base from onrushing zerg infested. Protect yourself from the relentless hordes during the night, and build up your forces to strike back during the daytime. Cooperate, or measure your survival in seconds.

To access the new content head into StarCraft II and select the Features section of the Join Game interface to start a match.

You can find all three mods featured on the StarCraft II community site's Maps and Mods page, where you can also check out great map making tutorials to teach you the techniques it takes to create your own mod masterpieces.
