Halo 3 Played at PAX
The avalanche of Halo 3 media is going to bury us all, and I won’t try to link to all of it, but it’s worth noting that Halo 3 was the surprise final game of the Omegathon at Penny Arcade’s enormous PAX expo – here’s a joysitq writeup. More entertainingly though, there are videos of the gameplay here and here, featuring commentary by Tycho.
