Do you mean the demo verison when you say raw version?I was wondering whether or not it is possible to play co-op with friends if one owns the steam edition and the other owns the raw edition?
Thank You!
I'm not sure. They should work if they're the same version. You can see the version in the main menu in the top corner (or by pressing TAB I believe). Otherwise you can just both play the non-steam version.With raw I mean the payed non-steam version.
