Speed Demos Archive and SpeedRunsLive have announced the dates for their next Twitch-based charity event, Summer Games Done Quick. From June 22-June 29, People will gather and try to play and finish classic and modern games as quickly as possible, in order to raise awareness and money for Doctors Without Borders. Twitch will stream marathons of the playthroughs throughout the week.

More than 150 games will be streamed, including The Legend of Zelda: Ocarina of Time, Final Fantasy VI, and Halo: Combat Evolved. Oh, and there are people who can control an octopus well enough to speedrun Octodad: Dadliest Catch. Their playthroughs will be featured, too.

The speedrunning groups have arranged for famous and brand-new players alike to participate. Well-known speedrunners include Cosmowright and Sinister1.

Viewers can donate and be entered into raffles for community prizes, as well. Donations and streams will be hosted on the event’s website, Gamesdonequick.com.

In January, the group’s winter charity stream, Awesome Games Done Quick, raised over $1 million for the Prevent Cancer Foundation. It’s always fun to watch speedruns, and there were some seriously amazing moments at AGDQ. If that event is anything to judge by, Summer Games Done Quick shouldn’t be missed.
