Virus Brotherhood

Virus Brotherhood is an arcade survival game set in a single drop of water. You play as a newly born virus in an ecosystem of billions of microbes, where hunger is constant and your life is measured in seconds. If your hunger timer reaches zero, you die permanently, so you must keep eating to survive.

Find food and avoid danger

Small, snowflake-like particles add 1 second to your life, while large green organisms add 10 seconds. A biological sensor at the bottom of the screen scans nearby organisms and marks safe food in green and deadly threats in red.

Fast predators pursue you and kill you on contact. Stationary giants use long, sticky tongues to pull prey in from a distance, while neutral microbes do not hunt but are still deadly to touch. You can push floating bubbles: some burst harmlessly, while others trap small prey that you can then eat.

Use your abilities

Four abilities recharge in 1–2 minutes, and special bubbles marked with letters can instantly restore the selected ability. You also have a dash with three charges, each of which regenerates in 45 seconds.

• Acceleration: dash rapidly to escape pursuers, but avoid crashing into a large enemy at full speed.
• Soundwave: send out an impulse that scares away nearby pursuers.
• Brothers: summon four allied fighters. While they are nearby, you become strong enough to eat anyone, but they also compete with you for prey.
• Spikes: temporarily make yourself the top of the food chain, causing other microbes to flee while you hunt former predators.

Evolve and score

The game tracks your points and survival time; the longer you last, the higher your score. Each new stage of evolution makes you larger, changes your appearance and gives you new advantages. After you die, an achievements screen appears, and a score above 1,000 points adds your name to the global leaderboard, which you can view from the main menu.

Your character moves automatically in the direction you point the cursor.
