Description
About This Game
EARTH IS YOUR FOOD
Swarm Idle is a prestige idle/incremental game where you command an alien queen and her swarm in the conquest of Earth.
Invade cities district by district, devour everything in your path, and face the Wardens standing in your way.
Grow your swarm, push your limits, then Mutate and start over stronger than before.
100 cities. 1,000 districts. One Earth to ravage.
GROW AND EVOLVE YOUR SWARM
Develop eight creature lineages. Buy levels, unlock upgrades and talents, reach new power milestones, and use their abilities at the right moment.
Then comes Evolution.
Sacrifice the levels and upgrades accumulated by a lineage to have it reborn in an immensely more powerful form. It starts again at level 1, but its potential has entered an entirely new scale.
MUTATE. START AGAIN. BREAK YOUR LIMIT.
When your progress finally hits a wall, trigger a Mutation.
Your swarm starts over from nothing, but your permanent power remains. What once took hours can now fall in moments.
Reach your former frontier. Break through it. Hit a new wall. Start again stronger.
Mutated Wardens provide Genome: keep it to directly strengthen your entire swarm, or invest it in nine Princesses that permanently reshape your progression.
CHOOSE WHERE TO CONCENTRATE YOUR POWER
Bioflux is a rare resource used to place Infusions on the lineages of your choice, directly increasing their damage.
Concentrate your Infusions on your strongest lineage or spread them across several creatures.
After every Mutation, they are returned to you: you can completely rethink their distribution with every new cycle.
In Swarm Idle, one question keeps coming back:
Where should you invest your next resource?
LEAVE. THE HIVE KEEPS WORKING.
Swarm Idle is designed to be left alone.
While the game is closed, your hive keeps producing. Come back a few hours or several days later: your resources will be waiting.
No offline time limit. No reduced efficiency.
Progress accumulates while you are away.
The decisions are still yours.
WATCH THE WORLD BE DEVOURED
Your conquest is more than numbers going up.
Thousands of creatures flow through the streets as a crimson tide. Wherever the swarm passes, the city becomes corrupted before your eyes.
On the world map, that corruption spreads around conquered cities until it gradually consumes the Earth.
100 cities. 1,000 districts. One finish line.
Swarm Idle is a premium, one-time purchase game with no microtransactions and no ads.
