Hello guys,

Has anyone completed all the achievements? I am having the greatest amount of trouble getting this last secret achievement without having an idea what it is. It is not even a very rare achievement either (Uncommon 11.5% players have gotten it). I thought it was Poison Control: cure poison 5 times in a mission, or All Aboard: Complete Confounding Light with more than 3 turns left on the timer, but neither are it. I did the cure thing many times with 5 med packs all used up on different soldiers, and I just finished the Confounding Light mission with 4 turns left and I still don't have achievements. Now all I have left is the No Sweat: Complete Deluge without activating more than 2 valves, but this one is not even listed on Steam.

Thanks in advance!

Solved: It turns out that you must activate the transponders over several turns and cannot be activated all at once and ending the mission. Not even over two turns I believe. If I were you, I would play it safe and activate one transponder each turn. Even though the achievements does not specify any restrictions on how this can be achieved.

It's probably something stupid like win a multiplayer match - which isn't possible with the GoG version.

Hmm... can't tell... I thought it was Xavier, but apparently that's not a hidden achievement on GOG.

They normally remove those when porting to GOG, but they seem to have removed more than just that. We're missing Poison Control or All Aboard (or both) as well. Odd, I think.

Do you have the game and completed it all?

I think, you could check the steam achievements of the game to find the secret one/s.
Poison Control is a Console only achievement (from what the XCOM wiki says) and according to the steam forums to get the all aboard achievement (just copied this from the steam forums) -> In order to get the achievement you have to activate the last transponder and enter the driving room in 2 different turns!

That is bullshit! I usually just save up the transponders and activate them all at the same time and run the train in the same turn so I don't have to deal with extra enemies.

Can you link this for me? I didn't get it. I have the save. I'm on turn 4 and saved the last transponder and activating the training on 3 turns remaining. I didn't get it.

I was hoping that you'd have that achievement, but I guess not.
