you will play the role of an intelligent virus created by a laboratory. Starting from your mouth, you will travel through the lungs, into the bloodstream, and then to the brain barrier, evading the pursuit of the immune forces, and finally invading the brain and controlling the entire host.

"Infectious Disease" - Conquering the Human Body with the Body of a Virus!
- In 2030, the Nine-tentacles Fish Biotechnology company synthesized a completely new virus in the laboratory, which was used to test the ability of simple synthetic non-cellular life forms to acquire new genes，to verify whether the human-to-human transmission of this virus will exceed that of COVID-19 and measles virus.
And you, the player, will control it to infect the human body.
- Core gameplay:
Control a single or a group of viruses with the ability to evolve. Start from the mouth, pass through the respiratory tract, lungs, blood, blood-brain barrier, and finally invade the brain neurons to control the entire body.
This is not a simple shooting game, but a microscopic war of survival, strategy, and evolution.
At the beginning of the game, the biological laboratory sprays virus particles into the mouths of the population for infection tests. The player controls the virus and avoids attacks from various immune factors, immune cells, various biological molecules, and electric current charges in the human body all the way from the upper respiratory tract. These attacks are either specific targeted attacks or indiscriminate wide-range attacks. The virus needs to move or use obstacles to avoid various attacks.
The virus destroys the alveolar cells of the human lungs, enters the cells, integrates the virus DNA into the nuclear genome of the cell, and continuously replicates the virus; enters the human blood circulation system, breaks through the blood-brain barrier, and finally reaches the neurons and infects the neurons, integrating the virus DNA into the nuclear genome of the neuron cells, completing a comprehensive infection of the human body.
Levels:
1. Upper respiratory tract, BOSS1 flagellate
2. Lower respiratory tract, BOSS2 macrophage
3. Alveoli, BOSS3 immune cell
4. Alveolar cell membrane, BOSS4 cell membrane protein
5. Invade the cell nucleus, BOSS5 endoplasmic reticulum and cell nucleus
5-2、cell nucleus
6. Escape from the cell interior, BOSS6 inner side membrane protein of the cell membrane
7. Control the infected cells from infecting the healthy cells of the blood system, no BOSS
8. Artery, BOSS8 capillary
8-2、Kidney
9. Vein, BOSS9 macrophage
10. Astrocyte, BOSS10 proteoglycan
11. Astrocyte, BOSS11 neuronal synapse
12. Neuron, BOSS12 neuronal model
13、Stomach
14、Stomach-Pylorus
- Strategy and Growth:
Viruses seize resources such as ATP, amino acids, nucleic acids, and lipids. They need to constantly evolve and learn to hide, accelerate movement, change their own charges, actively synthesize ATP, actively restore health points, and strengthen their genetic functions to enhance their infective ability and improve their survival capabilities, so as to eventually infect the entire human body.
Defeat each boss, seize their genes, and build your own evolutionary tree.
- The wisdom of the immune system:
When confronted with macrophages, T cells, antibody clouds, cytokine storms...
The immune system will learn to strengthen itself, will summon allies, and will set traps.
Only the most intelligent viruses can survive until the end.
- Science + Action + Strategy:
Based on simulated biological mechanisms: cilia clearance, lysosome degradation, complement system, immune system, neural voltage difference...
The game comes with an in-game guide and operation instructions. Play while learning, making education fun.
- You will experience:
Unique microscopic levels
Dozens of real cells and immune factors
A free genetic combination evolution system
Intense stealth + fast-paced combat + strategy
Scientific narrative style
You're not playing a game; you're becoming the next super pathogen.
—— Science has never been so dangerous, and viruses have never been so fascinating.
