Id do it. That is if im going. I havent decided yet if ill be going to Metro this year, but if I did Id probubly do a L4D (Left 4 Dead) Character atleast one of the days. (Either Ellis, A Hunter, or a Screamer.)
Id also have two friends with me, whom we havent decided on what group cosplay we'd be doing for atleast one of the days, so that would give you some group practice too.
If thats of any intrest to you, feel free to hit me up about it.
