At MAGFEST this year, Bit Brigade put on a show-and-a-half where they set up play-throughs of both Ninja Gaiden and Mega Man 2.
To watch someone play through hard games on stage at impressive speeds is one thing. To have a live band providing an accurate soundtrack to said games, that's something else entirely. One is awesome, and the other is really, really awesome.
But that's what happened, and the full video of the Mega Man 2 playthrough is up top for your enjoyment, and it's too cool for words. Like really, the video is where it's at.
