I am in the process of testing my map and i have some freinds that are unable to play custom zombies on there versions of the game. They have the steam version but i think it is a restriction on the game similair to it is on black ops ( the no crawler version ) i think cut and uncut versions.

Does anyone know a fix for this or a workaround to get there games able to play modded. Or is it just incompatible with that version of zombies altogether?

Thanks : )

Are these friends German? Cause we have a cut version here.
But there's a patch for that, can't remember where to get it though.

Yes they are and we got it by installing the UGX mod tools onto their games and it worked

I didn't know that's an option:D
But nice to hear that it works now.
