“There’s no official announcement from Frozenbyte about the
Linux client but it is available for download if you purchase it
from here.“Sadly, Frozenbyte describes the Linux client of Trine 2 as a
“testing version” for the moment, therefore users who bought the
game encountered various issues. See the Trine 2 for Linux forum
topic for more details.”
