About this game

THOUSANDS OF ENEMIES. ONE BASE. HOLD THE LINE.

The swarm is coming. Thousands of alien creatures pour across the map in a living carpet, and the only thing standing between them and your Nexus is what you build in the next ten seconds. SwarmZ is a real-time tower defense and base defense strategy game made for your phone, where every run is a fight against a flood.

You are the machine mind of Harrow Industries, an autonomous mining company with no people in it. Drop a Nexus onto a hostile alien planet, tap glowing crystal fields to feed your harvesters, and turn the crystal into guns before the Skitter arrive.

BUILD YOUR DEFENSE
• Place machine gun nests, cannons, flamethrowers and arc towers anywhere on the battlefield
• Wall off the approach and funnel the swarm into your kill zone
• Send harvesters out to the crystal fields: the richest crystal sits closest to the swarm, so every run asks eco or offense?
• Launch drones that hunt the swarm, guard your harvesters, heal your buildings and collect drops

CALL IN TITANS
Spend your crystal on a Titan, a giant walker with six-barrel rotary guns, and watch it chew through the carpet. Tap to select it, tap the ground to march it into the fight.

UNLEASH ULTIMATES
Aim a Tactical Nuke at the thickest part of the swarm. Freeze a whole field with EMP Stasis. Overclock every tower with Overdrive. Pick your loadout before each landing and time it right.

DRAFT, UPGRADE, REPEAT
• 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
• Spend what you salvage on a deep upgrade tree with branches for firepower, heat, arc, autonomy, fortification, economy and logistics
• Every run pays out, even a lost one, so you always come back stronger

FIGHT ACROSS PLANETS
Travel from planet to planet on a living globe, from the dry scrub of Mercy to the rust flats of Providence and beyond. Each region has its own layout, rock walls and chokepoints to learn. Something enormous moves under the desert sand, and when it surfaces the whole swarm runs for cover.

FEATURES
• Real-time swarm strategy with thousands of enemies on screen at once
• Pan and pinch-zoom across a large 2.5D battlefield, in portrait or landscape
• Turrets, walls, harvesters, drones, Titans and three ultimates
• Roguelite card draft and collectible card packs
• Alien planets and regions, each with its own layout and look
• Free to play with no ads, and your progress is saved to the cloud automatically, with no sign-up

If you like tower defense, base defense, survival strategy and swarm shooters, hold the line and see how long your Nexus lasts.

Download SwarmZ and make the swarm pay.

SwarmZ is made by LBC Studios. In the story, Harrow Industries is the in-game company you play.
