SamuraiCaveman: I've noticed that the Steam version of Giana Sisters is advertised with a special Halloween level. Is there any way to access this in the GOG version, do you have to download a patch? Or is it Steam exclusive?
Here is some news:
it's Halloween, today, and we have something special for you: Our designers reworked the Enchanted Mountain Path level of Giana Sisters: Twisted Dreams matching to the occasion. Experience new challenges and a ghost invasion in an exclusive night setting surrounded by spooky pumpkins.
Along with the Halloween special comes Patch 1.0.1 ......
We'll send out mails to you, this evening (CET), with the download link. For those of you who can't wait and use the Steam version of the game: It's already available there. GOG.com and GamersGate will follow this evening, too.
