The body is under attack.

The infection is spreading, and you are the patient's last line of defense.

In BIO SURGE, take control of an immune cell and enter different parts of the human body. Survive waves of pathogens, grow stronger, and defeat enemies and bosses as you work your way through the infection.

But survival is not the only goal.

Every organ is another step toward healing the patient.

🧬 14 Organs, 14 Battlefields

Travel from blood vessels to the brain, stomach, bones, and other parts of the body.

Each organ features its own environment, hazards, enemies, events, and boss. As you progress deeper into the body, enemies become stronger and the challenges increase.

⚔️ Fast-Paced Combat

Your immune cell automatically attacks suitable enemies, allowing you to focus on movement, positioning, and using your dash.

Move through enemy waves, dodge incoming attacks, collect experience, and choose new powers to strengthen your build.

Every run can take shape through different choices and combinations.

🧫 7 Immune Cells with Different Playstyles

Choose from seven different immune cells:

Neutrophil

Natural Killer Cell

Macrophage

Mast Cell

Dendritic Cell

Cytotoxic T Cell

Plasma Cell

Each immune cell offers a different playstyle and can suit different strategies and situations.

Unlock new cells with ATP as you progress, then permanently upgrade them using Boss Gems.

🧪 Build Your Power During Combat

Collect experience during each run and choose upgrades to increase your immune cell's power.

Create a combination that fits your playstyle and prepare for increasingly difficult waves.

There are 26 mid-run upgrades available in total.

🧬 Face Different Types of Enemies

Pathogens don't come in just one form.

BIO SURGE features 41 enemy types, including base and mutated variants. As you progress through different organs, new and more dangerous enemies enter the battlefield.

And at the end of each organ, a unique boss awaits.

14 unique bosses, each connected to one of the game's organs.

🩺 See the Patient Recover

Your progress doesn't only happen on the battlefield.

As you cleanse organs and advance through the game, the patient's condition is reflected through the game's interface. Vital signs, an ECG, and the patient's body status are all part of the experience.

Your ultimate goal isn't simply a higher score.

Heal the patient.
