Blizzard Launches Beta of World of Warcraft Cataclysm

Irvine-based Blizzard Entertainment said last night that it has launched a closed beta test of its new expansion for World of Warcraft, Cataclysm. The firm said the invite-only beta will provide the firm with feedback, find bugs, and address other issues. The company said it plans to launch the expansion later this year, which will be the third for the firm. Blizzard said its last two expansions to World of Warcraft "shattered" PC game sales records on release.
