A factory-building tower-defense rogue-lite where the production line is the weapon.

Infinitory mixes city-building, automation, and tower defense in a rogue-lite top-down game. Expand your base vertically in limited space, a strategic planning challenge. Automate resources to produce ammunition and upgrades, crucial for stopping waves of enemies on procedurally generated maps.

Infinitory is a rogue-lite where the factory builder and the tower defense are the same system. You land on a procedurally generated world and automate it: 70+ items, 100+ recipes, 80+ buildings, belts, pipes and power zones. Flat ground runs out fast, so the factory grows upward. And it has to keep the guns loaded. Turrets fire ammunition your factory makes, and they stop firing when it stops arriving.

Every factory pollutes, and the horde follows the pollution. Thousands of mobs move as one mass, handled by a solver written for this game. Sooner or later they get through. The base always falls, and that is the design.

What you keep is the score. It turns into levels, levels give you Battle Points, and you spend those points on a Battle Plan: the set of tech bonuses you take into the next run. You pick the plan before you drop and it does not change during the run. The best bonus in it sets your technology tier. Then you choose a biome and a difficulty and go again. A global leaderboard and a weekly featured seed give everyone the same rules.

In the late 1980s, a medical breakthrough went wrong. Researchers found a fungus that evolved inside its host and absorbed what it found there: immunity, regeneration. They pushed it through host after host, and it mutated beyond control. The miracle cure became VFC-89, the Virulent Fungus Contagion. It turned most humans and animals into monsters, ate through nature and brought the cities down.

One company had taken the threat seriously. Infinite Horizons, a small space exploration outfit, had spent years being mocked for an audacious orbital evacuation project. Nobody was mocking them when their Horizon Sanctuaries turned out to be the only way off the planet. The company everyone laughed at became the megacorporation that quietly runs what is left of humanity.

The Sanctuaries were never finished, and the materials to finish them are all still down there. You are a commander sent back into the fungal wasteland to extract them, with limited equipment and no margin.
