Portal: Still Alive Hits Xbox Live Arcade Next Wed, Promises Cake and Companionship at $15

Microsoft has announced that Valve's enhanced re-release of its wit-driven puzzle-shooter Portal will arrive in the Xbox 360's online Xbox Live Marketplace next Wednesday, October 22, priced at 1200 Microsoft Points ($15).

Titled Portal: Still Alive, the downloadable Xbox Live Arcade version packs the beloved original along with 14 new challenge maps and 6 advanced maps, but contains no additional plot details or commentary from the ever-present GLaDOS.

The "new" levels are based off those found in Hen Mazolski's free PC release of Portal: The Flash Version MapPack, sporting some subtle design tweaks but no major enhancements, Valve marketing VP Doug Lombardi revealed earlier this year.

"Aperture Science is pleased to inform you that your cake is indeed waiting for you and that the Weighted Companion Cube misses you in your absence," reads the release.

Valve previously released an Xbox 360 version of Portal as part of last year's mega-bundle The Orange Box, which is also available on PC and PlayStation 3.
