I finally finished the game and DLC. Riot mode was suprisingly fun. Overall I agree with what I think most people who have played it will feel.
It's decent. Has some great moments. The atmostphere is top notch and when it works, it works. One on one melee combat can be fun.
However, when the game sucks it flat out sucks. Certain sections dragged on for far too long and felt like a chore to get through, specifically the part where you get separated from another character and just when you get back together, you get separated again. Once enemies start to get tougher, the combat really starts to fall apart and in many parts I was not having fun. The checkpoint system was very iffy. The DLC had a bunch of hallucination sections and if I could get rid of one thing in games, it's those types of sections that cheaply manufacture scares.
The boss battles in this game were absolutely awful, especially a part that takes place on a platform. Fuck that part. I wanted to rage quit so often. Bullet sponges and things like switching weapons were such a huge hassle during tense moments. The game became cheap and I was not having fun in those spots. After I completed them and figured out a good way to attack, they were less awful, SO there's that.
Now that it's over and I know what to expect, would I recommend Callisto Protocol? Yeah, sure. I give the game a 7/10. Same score I give Starfield. Spiderman 2 and Alan Wake 2 got an 8.
If you do play it and aren't obsessed with achievements/trophies then play it on the easiest difficulty. Even on that difficulty you can still get killed.
