Maybe you came late. I get this error when I try to play and I don't know what the solution is and I'm also not very expert at that so if one of you can help me
Level00.tex isn't even something that's in the mod, that comes with Second Encounter to begin with. And it should be in TexturesMP anyway. Unless you're using Revolution, which relocates all files in MP folders to regular folders. And I don't have a libEntitiesMP.so file anywhere, so I don't know what that is. And why is the menu green?
Somebody did a Linux compatible version here, but I don't know how often they update it.
Btw, I should probably add that to the official links.
