Hi. The store page says there are achievements and shows one achievement in the most unlocked ones, yet I can't unlock them and GOG Galaxy shows the game as having no achievements.

The game does have Galaxy achievements, and I've been unlocking them if you check my profile. If you think you met the conditions for an achievement, check the in-game achievement list to see if it's unlocked there. I think some of them may be a bit bugged, I think I got some too early, such as 'Roast 5 enemies with one firewall shot'.

The in-game achievements seem to be not synching properly, I've gotten a few unlocked but then when you fire up the game again it says you have none unlocked when do.

I just unlocked an achievement yesterday by fully clearing a level. Reward was a cheat code. It's also registering in the ingame menu. You just don't get a popup message if you play offline (w/o GOG/Steam client).

(Update: That's actually not an achievement, just a reward for clearing a level completely.)

The whole seems to be wonky, prob due to it just coming out and having a day 1 update.

GOG Galaxy says I have 100% achievements.

To me it happened recently that I unlocked the achievement for finding the secret level in episode 1, but then I lost it again. This occurred with the offline installer, without the Galaxy client.
