Play Swarm Night online
Swarm Night is an arena survival game where your weapons aim and fire by themselves — positioning is the whole game.
Crawlers, dashers, and brutes pour out of the darkness in waves that grow thicker and meaner every minute.
Every kill drops a green XP gem. Scoop them up to level up and draft one of three upgrades: unlock orbit blades and frost novas, or stack damage, speed, magnet, and health.
Last 300 seconds and dawn breaks — you win. Your longest survival time is saved locally.
How to control Swarm Night
- Move: Arrow keys or WASD
- Move (touch): drag anywhere

- R: restart • M: mute

Tips for a better run
Keep moving in wide loops — standing still lets crawlers box you in.
Dashers telegraph with a pause before their lunge; drift sideways, not straight away.
Grab gems during lulls, not mid-wave: XP is worthless if you die collecting it.
Orbit blades scale brutally with blade count — take Twin Blade early.
Frost Nova's slow is your panic button: it buys space when the ring closes.
Hug the arena edge only to escape, never to camp — spawns come from the dark outside.
Frequently asked questions
How do I attack?
You don't aim — Spark Bolts auto-fire at the nearest monster, orbit blades circle you, and Frost Nova pulses on a timer. You only steer.
How do I win?
Survive 300 seconds until the dawn counter hits zero. Lose all your HP first and the run ends.
What do the upgrades do?
Each level-up offers 3 of 8 upgrades: bolt damage, fire rate, piercing, orbit blades, frost nova, move speed, magnet range, or max HP. Stack what fits your run.
What are the monster types?
Purple crawlers are slow but swarm in numbers, orange dashers lunge fast, and red brutes hit hard with big HP pools. New types join as the night wears on.
Is Swarm Night free?
Yes — it runs entirely in your browser with no downloads, no accounts, and no ads. Your longest survival time is saved locally on your device.
