Can't get achivements Invisible man, Rescue Ranger. I have passed Frontline level more then three times and get Hedge-hopper, but didn't get this 2 achievements. I saved red prisoners on Nazi's camp and saved red POW under the bridge on Red's camp. I do not know what's the problem.
Also I can't get Raider, Snake, Soft Touch and Thief. Is it bug? How can it be fixed?

I'm having trouble with an achievement Not a Rabbit. I hope someone finds some solution

For me it's the reverse. I get Invisible man, but don't get Hedge-hopper.
Before you ask, yes, I have killed the two soldiers at the start of the level, near the night vision device, I've got the scout/deserter killed, killed the two ingujred Red Line soldiers, killed the armored car driver and gunner, killed the 3 Red Line prisoners. Had no problems with the Steam version.
Also, the achievement for saving the Red Line soldiers isn't triggering either.
Not really important, but annoying.

I reinstalled and replayed the game, but still not received achievements. I don't know what to do. Not so important, but slightly disappointing.

Just do this steps I got my achievements with this https://steamcommunity.com/app/287390/discussions/1/350533172696204234/

Thank you very much! This method is working, now I can collect the remaining achievements.

Yes, this worked. Thank you.

In case this link ever gets broken i will explain for others here: You need to delete the appdata user.cfg (users/username/appdata/local/4agames) and let the game generate a new one. You might also need to delete the user.cfg file that's in the games base folder.

Achievement progress is stored in this file for some reason. So if you for example played the gog version previous to the achievements getting added you wont be able to unlock the ones the config file already has logged that you unlocked. So simply delete it and launch the game again to generate a new one. This might screw with the game settings(difficutly/keybinds) if you are mid game and don't want to lose your game progress/have your diffuculty changed by force then back the old one up.

I have a problem, in the SUMMER level of METRO EXODUS I have a monstrous bug. Artyom flies out of the room where I was talking with ANNA, I tried various configurations and even reinstalled the game, who could help me, the GOG people don't give me an answer
