Thanks, this looks like a huge amount of new broken achievements, soon I'll update the list.

Now more than ever, as many people as possible should contact the developers directly to ask for them to be fixed. I'm also reaching the character limit for each post, so soon I'll have to find a solution for my lists.

Terminator: Resistance - the following achievements don't work for now:
- Historian
- Blackout
- Priority to Me!

Decay of Logos - I haven't gotten any achievements to unlock so far

Bear With Me: The Complete Collection:
- Eye of the Seagull - Does not unlock and therefore:
- True Detective - Get all achievements cannot be unlocked

SUPERHOT:
Spread the system - Don't know if it's just me but I couldn't get this achievement to unlock

And thanks also to SCPM.

I've added all the games in the list on the forum. They are quite recent so I invite anyone interested in seeing these achievements fixed to write directly to the devs to solve the problem, now that development is still active.

I removed Rezrog and Niche from the list, because it would appear that the bugs have been fixed. If other people can confirm this they are welcome. And that's all for now!

All Terminator: Resistance achievements should now be working.

Great news, thank you! Terminator: Resistance removed from the list.

This War of Mine can be taken down the list as well. War Child related achievements have been removed some time ago.

Interesting, but I see two secret achievements at 0%, do you know what they are and if they work?

The only two achievements right now with 0.0%, that I can see are Note: Burn'em all and Epilogue: all the way.

Thank you, This War of Mine relocated in the "Achievements missing because the GOG version lacks some feature" section.

Damn this game is a doozie. I got a response from support, and as expected it's the ''make sure your firewall isn't blocking Galaxy' stuff like with Bioshock. Well, I've added Galaxy's processes and the game to the exceptions, tried running it without a firewall, even uninstalled Norton just to make sure it's not the cause. No dice. Now they're asking me to make sure that GOG.com domains are whitelisted. Any idea how to do that? Though given that no other game has consistently failed to reward achievements, I don't think this is where the problem lies. Other than that, all I can thing of is to redownload/reinstall the whole thing, try it on my old laptop, and try someone else's save file. And yeah, the same achievements seem to be working for others, they don't seem bugged globally.

Edit: It's done, Support have thrown their hands in the air, as have I. I'm getting a refund. Might seem petty to refund a game because of achievements but the complete disregard from the devs in their own tech support thread (and not just towards me) makes it easy to get over.

In Darksiders Genesis the achievement for defeating Belial appears to be broken. Based on the screenshot I've attached there appear to be a few other broken secret achievements as well; all boss fight related.
