Survival under a microscope in a limitless world.

You are a tiny virus that has just appeared in the merciless ecosystem of a single drop of water. There is no mercy here: billions of microbes wage a constant struggle for existence, and hunger is the main enemy. Your life is measured in seconds on the satiety bar. When it reaches zero, you die forever.

To survive, you must eat constantly.

Small colorful particles resembling snowflakes give +1 second of life each — there are plenty of them, and with careful play you will never go hungry.

Large green organisms are a real prize: each one grants +10 seconds at once.

At the bottom of the screen is a biological sensor: it scans everything around you and highlights

green — safe, can be eaten,

red — deadly threat.

The world is full of dangers:
— fast predators chase you and kill on any contact;
— stationary giants stand still but shoot out a long sticky tongue and pull prey from afar;
— neutral microbes don’t hunt themselves, but collision with them is also fatal.

Floating bubbles can be pushed. Sometimes they pop harmlessly, sometimes they become traps: small prey gets stuck inside, and you eat it with ease.

You have five powerful abilities that give you a temporary advantage:

Boost (key 1) — lightning-fast sprint that lets you escape any chase. Just don’t crash into a large enemy at full speed.

Sonic Wave (key 2) — a powerful pulse that scares away all pursuers around you. Perfect when surrounded.

Brothers (key 3) — summon four fighter allies. While they’re nearby, you become as strong as they are and can devour anyone. Your brothers are very greedy — you have to collect prey faster than they do.

Spikes (key 4) — for a short time you become the top of the food chain: all microbes panic and flee, and you can hunt even former predators.

Dash (left mouse button, 3 charges) — instant short dash in the chosen direction. Each charge recovers in 45 seconds.

Abilities 1–4 recharge in 1–2 minutes. Special lettered bubbles occasionally appear in the world — they instantly restore the selected ability.

The game keeps score and tracks survival time. The longer you last, the higher your result. With each new evolution stage you grow bigger, change appearance and gain new advantages.

After death, the achievements screen appears. If you scored over 1000 points, your name enters the global leaderboard, accessible from the main menu.

Controls are extremely simple: the character moves automatically, you only point the cursor in the desired direction.

The game features bright, vibrant graphics, but you can lower the quality or turn off sound completely in the settings for maximum comfort.

Virus Brotherhood is an intense arcade about the eternal struggle for life in a world we only see under a microscope. How many seconds can you snatch from this chaos?
