Games Done Quick is underway, with a $30 bundle of games to support its cause

The biannual Awesome Games Done Quick speedrunning marathon is underway, and through the coming week you can watch the action livestreamed right here. Gamers also can support the cause, which benefits the Prevent Cancer Foundation, through a bundle offered by the Humble Bundle folks.

Currently, a session with Mario Kart Wii will begin in about an hour, followed by runs at Mario Kart 64, Pokémon Red, Tomb Raider: Anniversary and a "mystery game." The event will then run for 160 hours until Saturday; you can see the livestream schedule of events here.

Awesome Games Done Quick is raising money for the Prevent Cancer Foundation, setting a target of $500,000. Just six hours in, it has already raised just more than $75,000 toward its goal. Last year it pulled in more than $1 million.

Humble Bundle has teamed up with the event to offer a name-your-price package of video games that include Duke Nukem 3D: Megaton Edition, Shadow Warrior Classic Redux, Oddworld: Abe's Oddysee and Volgarr the Viking.

Those who pay $6 or more also will receive Shantae: Risky's Revenge — Director's Cut, SpeedRunners (the Early Access game), SpeedRunners — YouTuber Packs 1 & 2 and a 30-day subscription to Twitch Turbo. At $10 or more, they will add Escape Goat 2 and a three-month subscription to livestreaming software XSplit Premium. A contribution of $30 or more includes all of the games, plus a special merchandise pack including t-shirts, buttons and other items designed by The Yetee.

Awesome Games Done Quick, which has events in winter and summer, supplied some of the most compelling video game theater of 2014. This year, more than 150 speedrunners will take a shot at world records in Contra, Descent, Shovel Knight, Mike Tyson's Punch-Out!! and more.

It will wind up with a run at The Legend of Zelda: Ocarina of Time on Jan. 10. (next Saturday), followed by a special finale event commencing at midnight Jan. 11 to celebrate the participants and gamers.
