Patias: I can confirm that the Noob achievement is not working on Shock Troopers. The problem with this achievement doesn't just exist on GOG, the Steam version has the same problem.

It is worth mentioning that the fact that GOG points out that this achievement was achieved by 0.1% of users of the game can be justified by two reasons:

A) Visual bug (less likely);

B) Use of illicit cheating programs.

In the Steam version the logic is the same.

I would also like to report that Caladrius Blaze Gathered Power achievement was not unlocked by me, even though I met the requirement twice.

Unlike the Noob achievement, I found no reports that obtaining Gathered Power would be in trouble with the GOG and Steam versions, so I think:

A) The fact that people have this achievement on both platforms may again be justified by the use of cheating programs;

B) For some reason, this is a random bug, which may affect some user. As it is a counting achievement, maybe some save problem? Do not know. Perhaps.

It remains for me to uninstall Caladrius Blaze from my computer and delete all save files to try a third and last time from the beginning. So as soon as I do, I'll be back here to update them.

Note that because this achievement in Caladrius Blaze is not possible, it is also impossible to obtain Fly Caladrius, whose goal is to obtain all the achievements of the game.

Skargoth: Train Fever

Philatelist: Receive 30 stamps.
Unlocks too early. Got it with 12 stamps.

Juggler: Complete a level with 10 simultaneously running trains.
Unlocks too early. I think I had around 4 or 5 trains simultaneously.

Mega-railroad: Complete a level with 300 track tiles.
I unlocked this on level 4. I don't think I had that many tracks built, but I'm not entirely sure.

falloutttt: Are you sure that "Train Fever" has achievements ? Cause it's not mentioned on the store page in any sense of the way.

Maybe you confused it with "Transport Fever" ?

Skargoth: Train Valley
Collector: Receive 15 stamps.

743x: i tried playing niche and none of the achievements work :c

Alexim: This isn't a good sign, but it might not be the fault of the game: in the past antivirus, firewalls and other programs have interfered with the achievements of GOG galaxy, have you tried to disable them?
