This Saturday, September 22nd will see Tom, Kevin, and Brian from Jetsville hold a Mega Man marathon called "Robots Love Animals" in a bid to raise money for the World Wildlife Fund. Starting at 10am, the group will be tackling all of the numbered Classic series games and Rockman & Forte, which they expect to "plow through." From there, it's on to Mega Man X, which will start with the first game and carry on through the sixth (or possibly eighth). Following that, their aim is to take out the four Mega Man Zero games. You can check out their planned schedule (to be updated throughout the run), complete with the first boss they intend to take out in each game and other statistics, right here.
As for the event itself, you can both watch and donate here.
