Made around 10 purchases there, still waiting on 2 pre-orders out of 3.

It's about 27$ on retailers here.I don't think you can find a cheaper copy ^^

on G2A.com it's for 24 E or smth like that :-? I can give you a referal if you wanna use it :D

It 28 dollars in here (DVD).It doesn't say anything about the steam but I guess it is the steam version.

Look at the offers here or on Nuuvem (not sure if it's ROW). edit: nevermind about Nuuvem, it's locked.

ON G2A its for 24.99E or something
