- (Some?) jumping lights have the wrong hitstun, Magneto can do like launch->sj.JabxN which is not even close to possible in the arcade/DC versions.
- There is occasionally the "alpha counter out and the leaving character gets hit anyway" glitch that was heavily present in the Xbox version. They started with the Xbox version as a base, unfortunately.
- There are a lot of sound bugs, because they play every sound on a separate channel rather than allowing them to interrupt themselves. This can throw off a lot of players.
- Some DHCs have the wrong amount of superfreeze, which can affect certain weird situations.
(- There isn't any slowdown. I realize this sounds good, but slowdown was what made some situations survivable and contributes quite a bit to gameplay.)
There is also magnetos air c.lk that recovers faster so doing the infinite causes air c. lk c.lk and opponent falls out. This happened to me at evo top 8 qualifiers match and the vid against me vs baby wolverine shows it. Then he goes and shit talks. Then I quit marvel at evo after that
EDIT:
BTW, since the xbox 360 achievements are a joke, I made some bonus achievements here.
Defeat opponent with 1 button only
defeat opponent with over 500 ping
defeat opponent with at least 10 snapbacks
defeat opponent while blindfolded
OCV (one character victory) your opponent with servbot
I challenge you to these online
