Multiply the squad. Survive the ramp.
Your squad charges up an endless ramp, guns blazing, and every gate you steer through does math on your army. Green gates add soldiers, gold gates multiply them, red gates subtract — but here's the trick: red gates can be shot. Pour enough fire into a −18 and it flips green before you reach it. Between the gates, crowds of red raiders rush downhill to thin your ranks and giant number blocks with four-digit hit points roll down the lane, crushing half your squad if you can't melt them in time. More soldiers means more bullets, so a fat squad clears the road ahead — until the gates get meaner, the hordes get thicker, and one bad choice unravels the whole run. How far can you push it?
Your squad runs and shoots automatically — all you control is where it stands on the ramp. Steer with a drag or the arrow keys.
Gates do math on your squad size: +N adds soldiers, ×2 and ×3 multiply them, −N takes them away. Gates come in pairs — you can only pass through one.
Red gates are targets, not walls. Every bullet that hits a red gate raises its value by one, and with enough fire a −15 flips into a green bonus before you arrive.
Red raider hordes charge down the ramp at you. Each one your bullets miss takes out one soldier on contact.
Number blocks show their hit points in big digits. Whittle a block to zero and it shatters for bonus points; let it reach you and it crushes up to half your squad.
Squad size is also firepower — more soldiers fire more bullets per volley. The run ends when your count hits zero, and score comes from kills, gates, distance, and your biggest army.
Swarmline is a free browser-based count-runner arcade game. Your squad charges up an endless ramp firing automatically while you steer it through math gates that add, subtract, or multiply your soldiers. Red raider hordes and giant number blocks come down the lane to thin your ranks — the run ends when your squad count hits zero, and your score goes on the global leaderboard.
Yes, Swarmline is completely free to play in your browser. No download, no signup, no paywall.
Gates arrive in side-by-side pairs and you can only pass through one. Green +N gates add soldiers, gold ×2 and ×3 gates multiply your squad, and red −N gates subtract. Red gates can be shot: every bullet that hits one raises its value by one, so with enough sustained fire a −15 flips into a green bonus before you reach it.
Score is 10 points per enemy killed, 25 per gate passed, 1 per meter of distance, and 5 per soldier in your biggest squad of the run. It is an endless run — difficulty keeps escalating until your squad is wiped, and higher scores rank higher on the leaderboard.
Yes. Drag anywhere on the screen to steer the squad — firing is automatic. On desktop you can also steer with the arrow keys or A and D.
