The Yogscast, for the last few years, have been doing charity livestreams every day in the month of December. They team up with Humble Bundle and various game devs to set up a specific Yogscast Bundle for the charities of the year.
This year they are supporting such charities as Cancer Research, Oxfam, and the Mental Health Foundation.
The Bundle includes multiple games, with more being added over the month of December.
All proceeds go directly to the charities, as well as all of the subscription fees paid on their Twitch channel. Be sure to follow the streams and donate where you can.
Enjoy the streams, enjoy the games, and give something back this Christmas.
