This game is basically Hard West+Cold War paranoia.

Didn't play Hard West? Understandable, it wasn't a big hit, but it was a grimdark Wild West turn-based tactic with crazy scientists, cannibalism, Satan and all that good stuff. Oh, and you couldn't miss in this game.
Okay, that last point is a bit miss-leading, because you and your enemies had luck counter, which depleted every time character dodged (if he dodged, because some hits were unavoidable even with ful luck). When that counter depleted fully, you would take a hit no matter the distance.
A lot of people didn't like it in Hard West and a lot didn't like it in Phantom Doctrine, but I think that's a fresh idea and it shouldn't be treated as if it was a capital crime, which was some people's reaction.

So what else is in the game, besides controversial combat system? A lot of paranoia, as I said. You build up your base, employ and train agents, brainwash enemies, put on your trenchcoat and fight conspiracies. Gameplay-wise it appears as tactical missions (stealth is totally viable and even desirable) and work at the base, where you travel through a lot of menus and do aforementioned training, brainwashing, crafting and connecting the dots to discover new missions, recipes and trainings for your agents. Not so much different fron X-Com (unlike combat system).

What about negatives? Graphics arent cutting-edge, the game DOES have some questionable quirks (like enemies not reacting when you break the glass near them), RPG system isn't very well balanced (some perks are obviously superior). Also, performance sometimes isn't stellar, but it was extremely rare and game never crashed or freezed.

So if you always wanted to save the world from Illuminati-like conspiracy (and read a lot of sanitized TOP SECRET documents), this is the perfect game for you.

And remember: Cold War was an inside job.
