Zoochosis for PlayStation 4

Play as a zookeeper

Zoochosis is a psychological simulation in which you play as a zookeeper tasked with pinpointing certain animals affected by a virus that mutated them. In this first-person horror game, you need to formulate a vaccine, narrow down the infected animals, and cure them while simultaneously trying to survive.  

Zoochosis offers thrilling and gripping gameplay that causes goosebumps all over your body. With its breathtaking 3D graphics paired with an eerily dark atmosphere, this game evokes a stimulating playability to keep its players wanting more while at the edge of their seats. 

Cure the animals and survive the night 

It is your first day at the zoo as a zookeeper. In Zoochosis, you care for the animals by interacting with them, preparing their meals, and cleaning their enclosures. By sundown, however, you realize that things are not what they seem. The truth is there is a virus breakout, and the animals are in grave danger. So, you must find a way to cure and save the infected ones. 

While the animals’ fate is in your hands, you must also exercise caution as some infected ones have gone feral and turned into unimaginable creatures. It should be reiterated that you must survive like the rest of the animals so they can make it out alive. So, make the smartest choice as the game's conclusion heavily relies on your decisions. 

This is a gory game that involves a lot of violence, blood, and body contortion, which is not safe for work viewing or appropriate for young audiences. In addition, this might not be suitable for easily frightened people or those who are dealing with mental health problems. Still, this is an exciting horror game with an amazing storyline that is worth trying. 

Smarter scares with Screamer System 2.0 update 

The Screamer System 2.0 update makes Zoochosis even scarier by adding dynamic, unpredictable monster encounters instead of scripted jump scares. Now, infected creatures—including deadly hallway monsters—can actually kill you, forcing you to stay alert at all times. The changes make threats feel more organic, with danger emerging naturally from the environment rather than cheap surprises. It’s a smarter, more intense kind of horror.

On the technical side, several frustrating issues have been resolved. Rare AI glitches—like animals freezing during interactions—are now fixed, and parasite screamers no longer lock controls during transitions. The giraffe boss fight has also been tweaked: since infected giraffes show no visible signs, the battle now triggers even if you attack the wrong one first. Minor level adjustments further polish the experience, ensuring smoother navigation and fewer stuck moments. Together, these changes refine gameplay while keeping the scares fresh.

A petrifying gameplay 

All in all, Zoochosis offers a hair-raising playthrough where you must care for animals and save the infected ones by nursing them back to their old selves with the vaccine while trying to survive simultaneously. With an array of conclusions, the ending depends on the path you take. However, it must be noted that this game involves a lot of blood and body contortion.
