OVERVIEW
Alright, check it out! So, there’s this crazy game, right? Picture yourself in the future, like 300 years from now. You’re playing as this dude named Jacob Lee, who gets stuck in this mega tough prison called Black Iron Prison, chilling on Jupiter’s moon, Callisto.
But hold up, things go totally bonkers when the other prisoners start turning into these freaky monster things! Chaos breaks loose, and Jacob’s gotta fight his way outta there if he wants to stay alive. Plus, there’s all these messed up secrets lurking under the surface of Callisto that he’s gotta uncover.
And get this, you’re not just fighting off these creatures with normal guns. Nah, you gotta be all strategic and stuff, using this gravity weapon and getting all up close and personal with those monsters, chopping off limbs and blowing off legs just to survive.

But it’s not just about the fighting. Imagine being stuck on this dead moon, with no one to help you out. That’s the vibe of Callisto, man. It’s like you against the universe, dealing with the messed-up prison and all the spooky secrets hiding on the moon.
Sounds intense, right? That’s the Callisto Protocol for you – a next-gen horror game that’s gonna have you on the edge of your seat the whole time!
