Campaign is too hard to enjoy, it all comes down to rng and prayer, so in that sense it's very much true to the Warhammer 40k universe. If you want the full grimdark experience of being a basic guardsman, man is this game for you. Victory will be torn from your grasp time and time again even if you play perfectly and you'll get to fight against despair and rage as the AI blatantly cheats and you get to do it all over again. Hell, the "third" Kharn campaign is litteraly gambling with blood - fun.
