Oh, hi... thank you for your reply... What you say about anti-cheat makes me think about cracks and stuff like that, and i don't know if that's what you mean... But in case it is, this game doesn't use anything like that since it's completely free. If by anti-cheat you mean that the program has something that just makes it impossible to run on Ubuntu, well, as far as I could see on AppDB, it is possible to make it work, but I just can't seen to find the way.
