This game is intriguing. It doesn't have that repetitive feeling that most games have. I learn something new each time, things I hadn't noticed before. It makes my heart pound. It's not difficult if you stick to it, but will it definitely have you saying a few choice words when you die. You have to start over....YES...no save points. Even with that, it's hard to put down. I'm playing in 4K, so the graphics are phenomenal. If you don't like a challenge, move along. I am crying like a little girl right now, because I played for an hour, got to the objective only to die a horrible death. Maybe you other players can scavenge my remains. I'd prefer you avenge my death. Bawahahahaha! The only reason I give it four stars is you have to put the game in rest mode if you want to take a break. I'm not a fan of that. If the power blips...well you know the rest.
