Just browsed through it. Disappointing, to say the least. I'd rather Capcom make spectator mode possible than "play through Arcade only using team Supers."
from what i've read on eventhubs, this mode seems super lame and I probably wont even bother with it. Here are some of the challenges
(from eventhubs.com)
1. Event Match 01, Arcade Finish Arcade with a diminished vitality gauge (final battle excluded).
2. Event Match 02, Arcade Finish Arcade without using Hyper Combos (final battle excluded).
