Galaxy doesn't recognise Trails from Zero having achievements. In spite of the store page saying it does have them, the My Progress section in Galaxy says it doesn't have any. Is it like this for anyone else? Is it a Galaxy error, or was the store page mislabelled? Games that have achievements, but that haven't been played still show them

Don't have the game yet but probably the developer (Durante) forgot to enable them. Probably might have to contact him (best option) or gog support (They will take days to reply) and let them know about it.

I replied to his messages. Hopefully he will see it soon

In the same vein of wondering how to get a response... I started a new topic as well, but does anyone else have problems getting controller support?

My DS4 works great with Sky 1-3 and CS 1-3. But CS4 and now Zero both act like there is no controller connected.

The only workaround I found for CS4 and I see does work for Zero is to add it as a non-Steam game and play it that way.

On the topic of achievements... CS2 doesn't seem to have them functional on GoG either.

Achievements seem to be up now

Thanks for letting us know. Have fun.

Interesting. So if I did that and uploaded my last save, would it tag all of them? Or would I need to play thought again?

You would have to play through it again :(
Anyways the game requires 2 playthroughs to get all the achievements so if you have a completed save just start a new game plus on Nightmare difficulty and complete the extra dungeons etc.
Plus if you play on new game plus and collect certain books there is a major plot in the story that is important for the next games.

Yeah. I started playing and some popped up
