Bioneers will have you build up an organism on the micro-scale that mixes together elements of factory-building with organism simulation. Sounds like it could be a fun idea!
With you mixing various different types of cells including muscle, skin, fat, bones, nerves and more. You need to somehow connect them all up into creating functional living systems like digestive, respiratory and others. It's all about creation and then survival.

Game Highlights:
Unique gameplay that combines factory-building with organism simulation.
Instead of buildings — cells, instead of conveyor belts — vessels, instead of enemies — viruses. The bigger your organism, the more powerful it becomes — but it also needs more resources to sustain itself.Animations inspired by real biology.
All cell and system movements are based on behavioral models from living organisms, creating a vibrant and believable microworld.A sandbox without limits.
Evolve as you wish: become an aggressive predator, a resilient symbiont, or a peaceful herbivore. Every choice affects your organism's evolutionary path.- Detailed customization.
Design your organism cell by cell, optimize systems, balance energy and resource consumption — you are the true creator of life.
