Donations are now open for Tip of the Hats, an annual charity livestream event benefiting One Step Camp and hosted by the competitive Team Fortress 2 gaming community. The event will start streaming live at twitch.tv March 29th at 12:00 PM EST. Last year's inaugural event lasted 36 hours and raised over $35,000 towards camp experiences and other educational and excursion programs for children with cancer. Players from around the world participated in the livestream and helped to make it one of the biggest events in Team Fortress 2 history, with more than 65,000 people tuning in.
