Before posting this review, I tried sending them a bug report through the 'contact us' form in their website.
Let me add that I am very experienced players at RPGs and this type of game (for instance I kept playing the old Captive for a few years).
After a few runs, I was very surprised to find some faction ratings getting very low very quickly (which there did not seem to be a reason for), so on my last run I picked a mission with only a low objective (+2 to a faction which was at 0, no negative factions results).
I went out of my way NOT to steal anything from that faction, nor do anything which could be considered hostile to them, and just before exiting the mission map, the faction rating was still at 0.
So, I exited the mission map, got the report that the faction was very pleased and that I was getting +2 as expected.
Then I immediately looked at that faction rating... it was now at -18
Besides this, I found that the RNG seemed to be rigged against the player, with fail rates in combats sometimes as high as 80% over the whole battle, against opponents same level who rarely missed.
Same apparently RNG 80/20 odds against the player on items interactions, for instance with terminals, using hacker.
This led me to make a save before every single action, which is really becoming tedious and should not be necessary.
Then when I validated my report for them, I got the message: 'Failed! The error occured, message is not sent. Please try again later.'
I saved my message as a notepad file, so far I got the same error every single time I tried to send it.
The current GOG version of the game is 1.0.2 from the 4th of July 2017
Until they fixed this, avoid this game.
