I finished the game and its Final Transmission DLC on Maximum Security (hardest difficulty in default gamemode). What I found was a magnificent experience
it has unique and wonderful gameplay

The Callisto Protocol is a third-person survival horror that impressed me a lot with its immersive environments and realistic graphics.

The motion capture work really elevates the experience and I was happy to see a few familiar faces with Josh Duhamel and Sam Witwer. Hoping to see a follow up or sequel in the future because I really enjoyed the story!

Overall rating, 8.5/10

If you're looking for a cinematic, horror game in space; this is it. First of all the obvious: the visual are gorgeous. The game is just so great to look at. And that really serves the purpose of this game, which is narratively focused and a cinematic form of combat.
I can certainly understand why some may not have enjoyed it but the game puts up close and personal when engage in combat. While you can run and gun, you are punished for doing so. Learning to dodge and focus on melee is your best option for most encounters.
The story is intriguing enough to keep you engaged. The level design is linear to keep you moving and not stay too long in one area. At times, I do wish the game picked up the pace.
Overall, if you're looking for a solid "B movie" horror story, cinematic and linear gameplay in a short 10-15 hour playtime, this is for you. Would recommend.
