"What is it that makes humans tick? Jump into the body and travel between organs. Follow the journey of blood and learn how humans function." ― Information Tab
Anatomy of Life is a limited time event which focuses on the Human Body. This event features 43 upgrades and 10 generators that produce either Deoxygenated Blood or Oxygenated Blood .
Story[]
Opening[]
"I'm consistently surprised by the ingenuity of humans. Could their biology be the source? After all, humans have an organic form. I do not. How do humans work? What makes them different from myself?"
Ending[]
"Just as I have nodes connected to an inner engine, humans are a sum of many parts working in unison. Humans have individual systems that are bound together, sustained by the blood running through them. They work like well-constructed machines. Maybe we're not as different as I thought."

Generators[]
Oxygenated Blood[]
Icon | Name | Description | Base Cost | Base Production | Requires |

![]() |
Heart | The body's centralized organ pumps approximately one gallon of oxygen-rich blood every minute. Long viewed as a symbol of life, some ancient cultures considered it as the center of thought and emotion. | 100 | 1/sec | Veins |
![]() |
Lungs | At the body's center of breathing, blood receives much-needed oxygen in the lungs. Now replenished, this arterial blood is sent back into the heart. | 1.00 E13 | 5.06 E8/sec | Skeletal Muscles |
Deoxygenated Blood[]
Icon | Name | Description | Base Cost | Base Production | Requires |
---|---|---|---|---|---|
![]() |
Brain | Three times larger than that of a chimpanzee, the human brain alone contains billions of neurons. It sends and receives the electrical signals that enable thought, emotion, and bodily function. | 1,500 | 1/sec | Brain Stem |
![]() |
Endocrine System | Glands of the endocrine system are organs that produce essential hormones. These chemicals carry messages through your bloodstream, instructing your body to perform specific functions. | 7.50 E6 | 120/sec | Parietal Lobe |
![]() |
Skeleton | A baby is born with around three hundred bones in their body. These bones fuse with age, forming the adult skeleton. Averaging two hundred and six bones, it is the framework that supports the human body. | 8.00 E9 | 250.000/sec | Hypothalamus |
