Slip on your comfiest lab coat, and get ready to forge creatures with scientific know how in this upcoming simulator game! Check out the demo for Monster Lab Simulator, coming out the next Steam Fest!

Monster Lab Simulator, developed by Round3 Studios, is a blend of two different genres. It combines a creature collector game with elements from the simulator genre. The simulator genre is vast, having restaurant sims and farming sims being in the same boat, so this game specifically simulates both a lab and shop.

You play as a humble scientist, with the goal of creating monsters in your laboratory. You create these monsters by synthesizing formulas and using them on eggs that you obtain. From there, it is all about experimentation, all to find new creatures to hatch and formulas to make.

These monsters, called Fulus, come in a variety of shapes and sizes, requiring different things to keep them in tip top shape. Some require specific diets, while some can be a fire hazard and need extra diligence in keeping. Your creatures care is important, as failure will hurt you when you inevitably try to make a profit.

That profit comes from two angles, that being through battling and store management, which feeds your research and experiments. The creatures you hatch and raise can participate in turn-based battles, both casual and ranked, for money and rare items. Your store serves as a way to sell off eggs and formulas you create, getting rid of extra stock to purchase more important things.

KEY FEATURES

Essence Synthesis & Egg Hatching – Mix mysterious essences, crack fragile eggs, and discover unique monsters waiting to be born.
Hidden Recipes & Surprise Creatures – Experiment with different combinations to unlock secret formulas and reveal rare Fulus.
Monster Training & Orb Protection – Feed, train, and strengthen your monsters with orbs, then add them to your permanent collection.
Turn-Based Battle Station – Test your team in strategic, turn-based combat. Join casual matches or compete in tournaments for big rewards.
Store Management – Place cars on shelves, set prices, manage stock, and sell to collectors or keep rare pieces to complete your own set.
Fusion Evolution – Merge three Fulus into one evolved form with stronger abilities, higher essence yield, and new combat options.
Lab Expansion & Upgrades – Invest your earnings into new machines, faster production, and advanced technology to power up your lab.
Mischievous Fulus – Keep an eye on naughty creatures and make sure your lab stays a safe, happy environment for them to thrive.
Rare & Legendary Discoveries – Push the limits of experimentation to unlock rare and legendary monsters hidden in secret combinations.

The demo for Monster Lab Simulator will release on October 13, 2025 during the next Steam fest. You can discuss Monster Lab Simulator on the PopGeeks Video Game Forum!

The first thing I noticed is how detailed the monster care system is. Some Fulus can be fire hazards, which is unusual for a simulator. It means you cannot just focus on making money; you have to really understand each creature. That makes the game feel more realistic. I also like that experimenting with essences can reveal secret recipes and rare monsters. I think this will encourage players to try new combinations instead of sticking to a safe path. The combination of battles and shop management creates a nice cycle where everything supports each other. I am looking forward to trying the demo to see how well the two aspects are balanced.

I think the store management side is more important than many players might realize. Selling eggs, formulas, and creatures is not just about making money but also about freeing up space for better resources. The fact that profits from sales and battles can be reinvested into lab upgrades makes the loop feel complete. I also enjoy that you have to watch mischievous Fulus because it adds some unpredictability. Games that make players manage both creatures and resources tend to be more rewarding, and I expect Monster Lab Simulator will do that well.

The detail about Fulus needing special diets and care immediately caught my attention. It suggests that the game is not just about hatching monsters but also about understanding their needs. This makes it feel more like a real simulation. I also like that you can train monsters and use them in battles, which adds strategy on top of management. The lab expansion and upgrades look promising because they create a sense of growth over time. I think the game could appeal to both simulator fans and people who enjoy tactical combat.

I am curious about the hidden recipes and rare discoveries. That element makes me think the game will have a strong replay value. You can keep experimenting and learning new combinations, which is motivating. The store management feature is interesting too because it provides a way to monetize your work and keep the lab running efficiently. Balancing care, battles, and business seems challenging, but that challenge is what makes simulators engaging. I am excited to try the demo and see how the game feels in practice.

I enjoy simulator games, but Monster Lab Simulator seems to offer more variety than most. The turn-based combat, shop management, and monster experimentation create a multi-layered experience. I like that mistakes in care or experiments have consequences, which adds realism. The idea of discovering rare or legendary monsters through hidden recipes is exciting and will encourage exploration. I think the game could appeal to both casual players and those who like deep systems. I am looking forward to the Steam Fest demo to see if it delivers on all these features.
