Didn't work for me on Ubuntu I'm afraid. It gets as far as the Unity Splash screen, then crashes.
If I strace it, the error might be:
openat(AT_FDCWD, "/home/user1/Trawl_Linux/Trawl_Data/Managed/System.dll.so.la", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
I looked in the dir, and the closest file to that is called System.dll
Hopefully that is some help. It's not a big deal for me, I have a Windows machine too to play it on.
