Zoo Anomaly Simulation is a first-person shooter set inside a zoo gone completely wrong, where mutated giraffes, zebras, and elephants have taken over and you are the last line of defense. The game drops you straight into the action with weapons ready and a creepy zoo environment to navigate, making every corner a potential threat from some oversized, distorted creature that used to be behind glass. Your job is simple: explore, grab gear, and put down the chaos before it spreads further.

What makes this game stand out is the absurd but genuinely tense premise. Fighting mutated zoo animals sounds ridiculous, but when a giant zebra is charging at you through a fog-covered enclosure, it stops being funny fast. The first-person perspective keeps the pressure up, and the variety of animal enemies means you constantly need to adapt your approach. Pick up weapons whenever you spot them and keep moving, because standing still gets you swarmed quickly.

If you enjoy free online shooting games, weird simulation games, or anything involving chaotic survival scenarios, this one delivers something genuinely different. Fans of first-person animal games, mutation-themed browser shooters, and quirky zoo games will find plenty to keep them busy. Zoo Anomaly Simulation works directly in your browser with no download required, making it one of the easiest free online simulation games to jump into whenever you have a few minutes to burn.
