About Monstrum

✦ AI summary

Survive a procedurally generated derelict cargo ship stalked by one of three deadly AI-driven monsters, using your wits and found objects to escape before permadeath ends your run. Each playthrough reshuffles the ship's layout, escape routes, and item locations, forcing you to adapt your survival strategy against unpredictable predators with different hunting behaviors.

Monstrum takes the traditional survival horror formula and remixes it completely with procedurally generated levels, permadeath, and AI driven predators, ensuring that nowhere on its derelict cargo ship is ever truly safe.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Monstrum is a procedurally generated survival horror game set on a ship that players find either thrilling or tedious depending on their tolerance for repetitive exploration and dated mechanics. The main criticisms center on monotonous level design with identical-looking corridors, predictable monster AI that camps in the same areas, engine issues, and unmissable sound effects, while defenders appreciate the tension when runs go well and the game's occasional scares.

buggy and annoying
Not recommended Sep 12, 2026
i used to watch youtube let's players play this game like a decade ago. i bought it myself years later and expected it to be good like i remembered but i was dead wrong. you wander around a ship with 1 million doors that all look the same to find items. the monsters chasing you are goofy looking rather than scary. and the story in this game is nonexistent. super repetitive and boring door opening simulator

While the game has it's negative moments due to older engine issues and some rather lackluster AI that love to camp the same area over and over again, if you manage to get a good run the game feels so good. Plus while the game is RNG, it's structure has enough anchor structures to help you orient yourself during gameplay. I just got super lucky and even then I enjoyed this a lot.

kinda spoopy

Mixed review: I feel like I would really like the game if it wasn't because every corridor and every room looks the same, it's very easy to get lost and I personally really don't appreciate that, it's a huge maze... I would like to beat it at least once! But I don't think it's for me. Also the sound of the lethal steam is really loud and I can't toggle it, that really bothered me.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
