Patias: Alexim, i discovered with the developer that this is a bug that can happen sometimes, so I made two more attempts and got it.
Apparently I was the first to get this achievement in GOG, as it still remains as 0.0%.
For those who occasionally fail to obtain it, it is then recorded that the process must be repeated. If it does not appear on the first, it will appear on the second attempt.
Thank you, in this case I remove the game from the list because the achievement is still obtainable, these messages remain for those who in the future had doubts.
PyL_: I don't know if it's a bug but the achievements of FORCED SHOWDOWN suddenly disappears one day.
My profile show 81% completion for the game but there are no locked achievements left.
The game page doesn't show achievements anymore.
It seems to be the bug that also hit Dragon's Lair and some other games, and yes, the achievements can still be earned but they are completely invisible until they are unlocked. Luckily the GOG staff can correct the problem in a few minutes, could you send a ticket?
And now good news,
Deep Sky Derelicts has now the achievements, a warm thanks to the developers who have listened to the requests of their fans.
This brings me to recall that
Deep Sky Derelicts,
Astrox Imperium,
Order of Battle: World War II and
Herald: An Interactive Period Drama - Book I & II are without the tag for achievements.
