This is a box map and 623MB? Is this a joke?I just tried out that map, no it is not
I strongly encourage you to continue with this project despite the remastered map. Maybe add a new side quest or new areas to explore to help differentiate it from the remaster. It has great potential and would be a waste to abandon it now.
Margwa is impossible for WaW, to much verts and joints etc. Not to mention the script + fx + anims.
