not that i know of

Not that I know I imagine that there gonna keep all the alternate Costumes a secret until we Play the game this Monday

I hope there is alt costumes.Change Kang's outfit already...

There's two different forms of alternates -- the completely different costumes which are usually unlocked, and the altered versions of a costume. The latter was automatically selected in the older games when both players selected the same character and costume... Which is the same setup for Shaolin Monks. My point is to not to expect anything flash... It's likely to be simple color switching (Kang's red tone will be replaced with a blue, for instance).

i dunno, i hope not..
i really hope they put some effort into multiplayer, but i think i already heard they w ernt. i heard it was just an extra :(
