Garrison Zero

Description

Garrison Zero is a free tower defense game about holding the last reactor on a frontier mining world against a swarm that feeds on heat.

On Hadra-7, people can only live along the Ember Line, a band of permanent golden dusk between a burning day side and a frozen night. Deep drilling there has woken the Kethra: glassy, bioluminescent heat-feeders that move as one mind toward the brightest thing on the planet, the colony's fusion reactor.

You command the Frontier Defense Corps, a militia of miners, welders and haulers armed with whatever the refinery can spare. There are no fixed lanes: every barricade and turret you place reshapes the path the swarm must take, so the battlefield becomes the maze you build.

Features

• Open-field mazing: walls and towers carve the route, and the swarm always takes the shortest path you leave it.
• Six weapon towers, each upgradable to Mk III with two tier-4 specializations, plus buildable barricades.
• Nine Kethra castes, from flooding skitters and wall-vaulting leapers to burrowers, flyers and a building-sized Hive Titan.
• Commander abilities: Orbital Strike and EMP Burst.
• A three-mission voiced campaign (about 20 waves each) and an escalating Endless mode.
• Mouse and keyboard or gamepad, rebindable controls, four quality presets and a built-in benchmark.
• Free, with no ads, microtransactions or in-game store.
