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 $77,000 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.
• [Update] GamingAngels has been auctioning prize packs since Friday and will continue through the weekend. The items for bid include swag from GamingAngels' own prize closet as well as donations from Electronic Arts, Capcom, Disney Online and PDP Gaming. Saturday's auction features a pack with a handsome Eddie Riggs statue from Brütal Legend. For more details, visit GamingAngels.
• PC game-maker Outspark is offering offering a "Help Haiti" bundle for four of its games from Jan. 15 to Jan. 31, each coming with a donation amount of $5. The bundles deliver in-game boosts and attributes, and all of the proceeds from their sale go to Yele Haiti, a relief organization founded by Haitian-born musician Wyclef Jean.
By no means are these the only ways gamers may contribute. The text-message fund raising campaign has generated more than $10 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.
