An alien spore lands on a real map of Earth. Spread across 2,450 hexes and 144 countries before humanity finishes the cure. No ads, no purchases.
An alien spore fell to Earth. You are the bloom.
Pick a strain, pick a response level, then pick a single hex anywhere on the planet to land on. From there the bloom spreads on its own — hex to hex, along coastlines, through airports and shipping lanes — and you spend Biomass to push it somewhere it would not have reached alone.
Then humanity notices. That is the whole game: spreading fast gets you seen, and getting seen starts the clock on your own extinction.
A REAL MAP The world is not decorative. 2,450 land hexes carry their actual country, climate band, coastline and a share of that nation's real population. 144 countries, 121 transit hubs built from real cities, and 554 air and sea routes. Bangladesh really is the densest ground on the map. Greenland really is a problem.
HUMANITY FIGHTS BACK Countries raise their alert level, seal borders, quarantine hexes and fund purge teams that burn your colonies back — including ground you had fully consumed. Every wealthy, functioning nation pours money into Cure Research. Hit 100% and you are gone. Saturate all 2,450 hexes first and the planet is yours.
SIX STRAINS, SIX DIFFERENT GAMES Vector-7 is the balanced one. Mycelia is slow and nearly impossible to purge. Grey Cascade rides transit networks and guts cities but starves in open country. The Hollow is almost undetectable and barely feeds. Static gives the labs nothing to sequence, so the cure stalls — but it crawls. Null Bloom voids ground permanently, and every lab on Earth is working on you.
46 MUTATIONS Three branches — Transmission, Resilience, Virulence — bought with Genome you earn by infecting and by catching floating pickups. Airborne spread, cold tolerance, quarantine bypass, transit latency, and a lot of ways to make yourself harder to notice.
THE LAB Between outbreaks the Lab cultures Xenite in real time, including while the app is closed, up to 12 hours banked. It buys permanent upgrades that carry into every future run.
ALSO:
- Daily Outbreak — one fixed seed, everyone plays the same world
- Cascade — endless waves
- 37 awards
- Runs survive being force-quit; resume exactly where you left off
- Every sound is synthesised at launch. The soundtrack tracks how close the cure is to finishing.
No ads. No in-app purchases. No premium currency. No accounts, and it never needs a connection.
