About the Game

🧪 About

This is not a simulation. This is a biological warfare laboratory.
Develop bio-weapons by manipulating DNA in your own lab. Synthesize synthetic bases, design custom DNA sequences, engineer lethal viruses, and prepare them in injectable form to unleash upon the world. Every failure brings you closer to a stronger variant.

🔬 Key Features

🧫 20 Unique DNA Bases

Utilize your collection of natural and synthetic bases to create diverse effects. Strategically combine properties such as toxicity, mutation potential, spread rate, and tissue-targeting effects.

🧪 Chemical Crafting System

Order components from the deep web, receive them at your lab, and craft your own bases by mixing the correct proportions. Crafting requires knowledge, not just ingredients.

🧬 DNA Sequence Editor

Create custom DNA strands of up to 100 bases. Decide which base goes where and when to modify it—your choices determine the fate of the virus.

🧰 Automatable Laboratories

Manage the entire process—from synthesis to purification, replication, and preparation for injection—with a single, real-world-inspired device.

🧉 Vaccine Production

Design an effective vaccine against your own virus. Inactivate the virus with heat, strengthen it with adjuvants, formulate, and test.

🌐 Gameplay Based on Real Science

  • Deep systems grounded in synthetic biology, molecular genetics, and virology.

  • Simulate the behaviors of your custom-designed viruses.

  • Simplified but coherent representations of synthesis, PCR, purification, and injection steps
