I was thinking that a dishonored multiplayer would be pretty cool, things like maybe not player vs player, maybe like co-op type things, or possibly Assassin vs Guard (player vs player What do you think?

Discussed here. My answer is still "no".

I think Co-op would be fun, maybe like Rage or something where there are special mission that compliment the main story line, but the missions are Co-op

I would say no unless supernatural abilities are disabled.

Yea actually, play as like 2 of douds ex assassins trying to get revenge for some deep emotional or moral thing.

Let's move this over to the existing thread. Thanks for the link Sylthia.
