About this game
Mutant Fish Lab is a simulation game that blends genetic experimentation with auto-battling chaos.
Summon mutant fish with strange combinations of traits and abilities, toss them into the tank, and observe their behavior as they battle it out automatically. Fish that survive gain experience, level up, and mutate into even more powerful (or unpredictable) forms. Once you find an interesting mutation, you can extract and replicate it for future use.
Strength isn't always the goal. In some challenges, you'll need to design the weakest fish possible—one that dies first. In others, you'll need fish that can dash across the tank dozens of times before time runs out. These missions test not only your creativity but also your ability to engineer the perfect lifeform for a very specific task.
With countless ability combinations, procedural mutations, and strategic design choices, Mutant Fish Lab invites you to experiment, collect, and push the limits of what a fish can be.
