Heals 4 Reals is a new charity event taking place Saturday and Sunday, 9AM to 6:30PM PST both days. Tune in for some rocket jumping, an ultiduo tournament, and more, all benefiting the American Foundation for Suicide Prevention. You can watch the event when it's live on the KritzKast Twitch Channel.
In addition, they've partnered with ScrapTF to provide item donations for the event. Just like with Tip of the Hats, you can donate TF2 items and they'll be converted directly into cash and sent to charity.
