Today only, 100 percent of the proceeds from purchases in PopCap's store - they make Bejeweled and Peggle - will go toward Haiti quake relief. This post is our official open thread on ways to contribute to the recovery.
• On Wednesday and Thursday, Bungie is encouraging Halo 3 and Halo 3: ODST players to don a Haitian-relief emblem in game, and will contribute up to $US77,000 to the cause depending on the number who participate. A special T-shirt also is for sale in the Bungie store, the proceeds of which will go to recovery efforts through the American Red Cross. See this post for more details.
• Zynga, makers of games for Facebook and social media, has also opened a fund drive to help Haiti through the World Food Programme. It joins the company's pre-quake philanthropic efforts to help the impoverished nation. More details here.
• PopCap's sale will go until 11:59 pm. U.S. Pacific Time tonight, and will benefit Haiti through Partners in Health.
By no means are these the only ways gamers may contribute. The text-message fund raising campaign has generated more than $US10 million in aid and contributions now may also be made through iTunes [link will open iTunes] . And certainly there are other worthy means of contributing.
Feel free to list them in the comments here, and please send any game-specific efforts (undertaken by companies, studios, or groups of gamers themselves) to tipsATkotakuDOTcom. I'll be glad to add them to the roundup.
