Monster Lab Simulator

Round 3 Studios developed and published Monster Lab Simulator. Basically, this cozy management game turns you into a mad scientist. You run a busy laboratory filled with strange machines and cute monsters. Consequently, the game perfectly blends basic store management with deep creature breeding.

About the Game

First, the game gives you a very simple daily loop. Therefore, you buy raw eggs, inject them with colorful serums, and wait for them to hatch. Furthermore, you can sell your fresh adult monsters to eager buyers for huge profits. As a result, earning cash lets you slowly buy bigger tanks and better science gear. Moreover, the game constantly rewards you with new chemical recipes. Thus, mixing rare serums creates totally unique monster breeds.

Key Features

Monster Breeding: Specifically, you control exactly how your creatures grow. Thus, injecting different serums changes their final stats and cute looks.
Lab Upgrades: Next, you must spend your hard-earned cash wisely. Indeed, buying faster incubators helps you hatch rare eggs much quicker.
Arena Fights: Also, the game lets you test your best monsters. Consequently, entering automated arena battles earns you special prizes and rare loot.
Deep Fusions: Meanwhile, you can combine adult monsters together. For instance, merging two weak creatures creates a massive, fully evolved beast.
