Well, I haven't played it yet, so I COULD be wrong about this assumption, but it kind of reminds me of how many hated the combat loop you pretty much had to adhere to in Halo Infinite, which I myself struggled with at first. I ended up finding though that once you get the details of it engrained in your playstyle to where you didn't have to think about it, it became a MUCH more enjoyable game. In fact I ended up finding that I didn't even really need to do the fast switching of multiple weapons and lots of fancy aerial combat many were doing to beat the game, and even did so on Nightmare with no upgrades. Truth be told, I tried and tried to use those fancy tricks, but at 64, didn't have the reflexes and dexterity for it.
That said, from the amount of gameplay I HAVE seen of Calisto Protocol, I could see how just sheer boredom might be a problem, since it's combat loop is FAR simpler with just melee, scant few weapons, and Kinesis tosses into fans, etc. Sometimes when you go for sheer horror via only being able to use minimal tactics for combat, you wind up with the dreaded tedium syndrome.
