Content: gore, dismemberment, blood, nudity, violence, strong language.
Zoochosis is a first-person bodycam horror game by Clapperheads about a zookeeper's first night shift. Between preparing food and cleaning enclosures, you test the animals for an infection that turns them into monsters, cure the ones you can and deal with the ones you can't.
About Zoochosis
Zoochosis is made by the studio Clapperheads, which published it on Steam with Storymode on September 30, 2024. It reached the Epic Games Store and PlayStation in August 2025 and Xbox in October 2025.
You've taken a night job at a zoo that's been shut for a long time, and nobody will say why. The work is real work. You cut blocks of food to each animal's recipe at a kitchen terminal, load your cart, ride a little train out to the enclosure and drop the meal off. Then you follow the animals around and check them. That means taking their temperature, listening for anything off, grabbing a stool sample and drawing blood. Stool and blood go back to the train for analysis.
Something is wrong with some of them. Which results come back bad tells you what the animal has, and you mix a cure and fire it in with a dart gun. Wait too long, though, and an animal turns. Heads split open, legs stretch into spider limbs, a giraffe ends up with a spiked tube for a mouth. Then it's a fight, with a stronger cure or lethal rounds, while the monster goes after you and the healthy animals alike. Which animals you save, and whether you make it, decides which of the many endings you get.
The mutant designs are what made it go viral when it was announced. Bloody Disgusting liked that idea but found the testing routine tedious, the aiming loose and the story familiar. It's short: around two hours for a first run, and finishing opens a New Game+ with an extra animal. Players are split, with Mixed reviews on Steam. It's for people who enjoy a job routine slowly going wrong, as in The Mortuary Assistant, and don't mind gore, nudity and dead bodies.
How to play Zoochosis
- Buy Zoochosis on Steam, the Epic Games Store, PlayStation or Xbox and start your first shift.
- Prepare each animal's food at the kitchen terminal, load it on your cart and take the train to its enclosure.
- Check each animal: take its temperature, listen to it, collect a stool sample and draw blood, then analyse the samples on the train.
- Work out what the infected animals have, make the cure and deliver it with the dart gun.
- If an animal turns, hit it with a stronger cure or lethal rounds before it hurts you or the others, and survive the night to reach an ending.

Tips
- You can only hold two tools at once, so plan which checks you'll do before you walk away from the cart.
- Some animals get agitated enough that you have to tranquillize them before you can draw blood.
- Your choices about which animals to save change the ending, and finishing once opens New Game+ with an extra animal.
