Posted in the X-Men thread, but things can get lost over there. =)
First vid: All the heroes, and a tutorial on how to play them. I do screw up Prof X, because I didn't notice the Brotherhood targets flashing on the right. Brief look at the Danger Room Wizard at the end.
Second Vid: Starting and completing all the Villain Modes, with narrated tutorials on how the rules work for them. Nightcrawler shows up, too. (Omega Red, Juggernaut, Shadow King, and Sabretooth are in this vid).
Third Vid: The remaining Villain Modes (Sentinels, Brotherhood Multiball, Hellfire Club MB), along with the very, very, very sweet Dark Phoenix wizard mode. Seriously...watch that ending animation. Holy crap. The vid is narrated with a tutorial on how the modes are played.
Videos are currently rotating 90 degrees, but it will take a while to process.
