With World AIDS Day coming up on December 1st, Twitch is partnering up with (Coca Cola)RED for one week to help fight the disease in sub-Saharan Africa. On December 2nd, you can stream Twitch's Arena of Valor channel and watch eight popular streamers face off playing the mobile MOBA designed by Tencent Games. There will be a way to make donations during the stream, of course, and if you're a streamer, you can gather donations for the entire week, too. Coca Cola will match up to $50,000 of all donations gathered during the week.
