Thanks for yor reply, BaronSmoki!
Once you enter the bunker (more or less in the middle of the game) the game gives random errors and crashing, making it unplayable. The error code is something like visual c++, R6025, It seems to be related to the flickering effects of the bunker lights.
I have tried Compatibility Mode, but it doesn't work. Also tried installing all c++ packages and using dgvoodo2 and dxwnd, but the bug keeps crashing once you enter the bunker.
According to Steam comments, this doesn't happen when playing on windows 7. I have no idea what Windows 10 does differently to make this happen.
I have a save just before entering the bunker, where the bug appears, in case someone has the game and wants to fight a bit to find the solution.
Thanks again!
