This way too, man. I bought it yesterday and so far no achievement has appeared. That's new for me. I've played it a lot, on another account, I've all been fine.

yep all were bugged i got tiny troopers two and thankfully they work there . If you are an achievement hunter and actually want all achievements in your games then i use a method to get bugged ones i can tell you if you want .

Achievements are not bugged. I got them just fine.
Weird it's happening to some people.

yep weird also in the settings could you open the achievement tab , I could not open that so maybe that is why?

Do you have Steam overlay disabled because that just opens up the achievement page on Steam overlay?
I used to disable it but some games didn't unlock achievements without it, even though it worked for most of the games.

I have it enabled.
