After raising more than $1 million earlier this year with its charity marathon, Games Done Quick is holding a summer marathon to raise money for Doctors Without Borders.

The event begins this weekend, Sunday June 22, and goes until June 28. If you're unfamiliar, the event is a gaming marathon that raises money for charities, but it focuses specifically on speed-running games. This weekend, you will see a number of speed-run classics like Super Metroid and Goldeneye, but you will also see players speed-running new games like Super Mario 3D World and The Legend of Zelda: Skyward Sword.

For more on the event, including the full schedule of planned games, head here. The stream will be hosted on the Speed Demos Archive channel.
