OneBigGame have today announced that Chime (developed by Zoe Mode) will be released on Steam for the PC at the “end of this summer”. A proper date hasn’t been confirmed yet. The game was released on the Xbox Live Arcade earlier this year, and 100% of proceeds from that (between February 1st and June 1st) went to OneBigGame. 5% of the purchase price of royalties for the PC version will also be donated to OneBigGame. The PC version will also include “Still Alive”, the famous end-song of Portal.

“We are very pleased with Chime’s performance on Xbox LIVE Arcade for Xbox 360 and want to thank Zoe Mode for their creativity and generosity,” said Martin de Ronde, Director of OneBigGame. “The game has proven to be a great fund-raiser, a quality game in its own right and possibly the basis for a unique, new franchise for Zoe Mode beyond our exclusivity period.”

Ed Daly, Managing Director of Zoe Mode, added, “We are proud to have been able to kick start the unique fund-raising initiative that is OneBigGame and are very pleased with Chime’s impact. Because of the success, we were really keen to broaden Chime as a franchise by releasing a Windows PC version. We also want to continue supporting OneBigGame beyond the exclusivity period and have decided to donate a percentage of the royalties of any future Chime title we make. Finally, we’re proud to work with Valve on the Portal soundtrack level for Chime and have done our utmost to ensure the new level is one of the best yet for Chime.”
