Thousands of enemies. One base. Hold the line.
A real-time swarm defence game for your phone. Build turrets and walls, call in Titans, and keep your Nexus standing while the whole map comes for it.
The swarm
A living carpet of teeth.
The Skitter are the planets' native fauna, and they do not stop. Thousands pour across the map at once, flow around your rocks and walls, and chew through whatever they reach: your turrets, your harvesters, your Nexus.
- ScuttlerThe swarmer. Weak alone, endless together.
- DarterFast and fragile. It gets past what you did not cover.
- ShieldbackArmoured and heavy. It soaks up fire so the rest can pass.
- SpitterHits you from range, so walls alone will not save you.
- QueenLeads the final wave. Make it count.

Build the line
Ten seconds to dig in.
Place towers anywhere on the battlefield, wall off the approach and funnel the swarm into your kill zone. Send harvesters to the crystal fields to pay for it all, then decide: economy or firepower?

Machine gun
Cheap, fast and everywhere. Shreds the front of the carpet.
Cannon
Heavy shells that blow holes in packed groups and armour alike.
Flamer
A cone of fire for the chokepoint. Nothing crosses it quietly.
Arc tower
Lightning that jumps from enemy to enemy, hitting a whole cluster.
Upgrade tiers
Level a tower and it evolves.
Every tower grows through three marks. New bodies, new guns and a new way of firing, so a veteran line looks and sounds nothing like day one.
Mk 1
Standard issue
- Machine gun
- Plain tracer fire.
- Cannon
- A standard shell and blast.
- Flamer

Mk 2
Refitted
- Machine gun
- Two white-hot fanned streams.

Mk 3
Prototype

- Cannon

- Flamer
- A broad violet plasma sweep.
- Arc
- Violet, six forks and the widest strike of all.
Harvesters
Drive out to glowing crystal fields and pay crystal every second. The richest fields sit closest to the swarm.
Drones
Hunters strafe the thickest swarm, Guardians watch your harvesters, Menders repair, Gleaners collect the drops.
Walls
Pieces you drag out in a line. Bend the swarm's path, and repair what they chew.
Four planets
Mercy, Providence, Solace and Concord, each with its own layout, rock walls and chokepoints.
Titans
Call in walkers.
Spend your crystal on a Titan: a giant walker with two six-barrel rotary guns. Tap one to select it, tap the ground to march it into the fight, and watch the guns spin up and chew through the carpet.
The Maw
Something large is below.
Something enormous moves under the sand. When it surfaces it wrecks your harvesters, towers, Titans and walls, and the whole swarm runs for cover. You get one warning.
Seismic event: the Maw is risingUltimates
Three buttons you save for the worst.
Pick your loadout before each landing, then time it right.
Tactical Nuke
Aim it at the thickest part of the swarm and wipe the field.
EMP Stasis
Freeze a whole field of enemies in place while your towers work.
Overdrive
Overclock every tower at once for a window of pure firepower.

Cards and packs
Draft. Rip. Upgrade.
Between waves, draft one of several cards for a boost that lasts the run. Open card packs to level up your turrets, drones and Titans, and spend what you salvage on a deep upgrade tree. Every run pays out, even a lost one.
- Common
- Rare
- Epic
- Legendary
Upgrades
650+ ways to get stronger.
A tree of 91 upgrades across seven branches, 40 of them ten ranks deep, plus ten levels for every turret, walker, drone and building you unlock. Every run pays for the next one.

Onyx
The voice in your headset.
Harrow Industries is an autonomous mining company with no people in it, and Onyx is its machine mind. She coaches you through your first landings, calls the threats, and tells you straight when it is going badly.
- “Seismic contact. Something big is under us.”
- “Final wave. There's a Queen with them.”
- “Site secured. Good work, commander.”
In the field
