About this game

About This Game

This is a casual roguelike game where you become nanomachines to protect the human body from viruses and bacteria.

As time progresses, the human body ages and becomes increasingly vulnerable to viruses, bacteria, cancer cells, and more.

Nanomachines come with a power-up feature.

Acquire various weapons and eliminate external threats!

Viruses and bacteria become stronger over time, so strategically upgrade your weapons to stay ahead.

Nanomachine weapons can evolve into extremely powerful “Synthesis Weapons” when specific conditions are met.

Experiment with different combinations and discover them all!

Game Tips:

・Focus on collecting experience points first. Start by defeating enemies you can handle.

・Survival is key in the early game. Master the art of dodging and running away effectively.

・Look for items on the map. Don’t miss chances to heal or power up!

・Find weapons that suit your playstyle. Your strategy will change depending on the combinations you choose.

• Actively obtain Synthesis Weapons to gain the advantage!
