I don't know what the MP will be like but it since it can't be all I'm gonna mention all at the same time, I hope they add something along thse lines as well:
2 people run through the same stage at the same time and they compete for those gruesome "style" points,
Co-op beating the grab out of hordes of baddies
Maybe a death match mode where 2 people go after each other by being offered specific objects to kill the other with.
