Bioreactor Function and Dispelling Corpse Myths
The Bioreactor stands among the most frequently misunderstood technological fixtures in Graveyard Keeper 2. Because of its ominous brass framework, pulsing green coolant reservoirs, and inclusion within the cemetery factory progression, newcomers often mistakenly assume the machine functions as an incinerator for unwanted cadavers or an electrical generator.
In actual game mechanics, the Bioreactor never accepts corpses, burns human remains, reanimates undead minions, or provides grid voltage to factory tools. Instead, it serves as a specialized chemical refinery designed to extract high-density biochemical catalysts from cultivated agricultural crops.
Feeding the Bioreactor raw organic material produces an invaluable late-game crafting reagent designated as Zombie Power. Understanding this true operational purpose prevents players from fruitlessly dragging cadavers into the industrial basement.
Wheat Conversion Ratios and Autonomous Output
The primary input consumed by the Bioreactor is standard harvested Wheat from your surface gardens. The internal conversion ratio is strictly deterministic: feeding five bushels of raw Wheat into the machine intake hopper yields exactly one unit of concentrated Zombie Power.
Each distillation cycle requires approximately fifteen seconds to complete and operates without consuming fuel, firewood, or supplementary alchemical powders. Unlike autopsy benches or blacksmith anvils, the Bioreactor operates one hundred percent autonomously without requiring a stationed zombie operator.
As long as fresh wheat sheaves continue to arrive along the input conveyor, the internal agitators churn continuously, depositing finished Zombie Power canisters into its integrated output receptacle until storage reaches maximum capacity.
Factory Conveyor Integration and Surface Farming
To maintain continuous Zombie Power fabrication without manual intervention, integrate the Bioreactor directly into your surface agricultural supply chain. Establish automated garden plots on the surface farmed by dedicated agricultural zombies equipped with bronze shovels and wheat seeds.
Route harvested grain bundles through the surface garden cargo hatch, which gravity-feeds down directly into the subterranean factory cellar. Connect the bottom of this cargo chute to a motorized conveyor line that terminates at the Bioreactor intake hopper.
Placing a buffer chest along this transit route ensures excess grain harvested during peak growing seasons is safely stored, guaranteeing a smooth and uninterrupted feed into the Bioreactor even during dry seasonal planting rotations.
Zombie Power Reagent and Mechanical Fabrication
Zombie Power serves as the indispensable technological catalyst required for fabricating advanced mechanical hardware. Combining Zombie Power canisters with precision steel brackets and clockwork springs at the Machine Assembly Bench produces Zombie Mechanisms.
These advanced Zombie Mechanisms are vital components required for constructing high-tier pneumatic sorters, autonomous freight lifters, and Tier 3 Town Warehouse supply orders requested by civil restoration inspectors. Establishing a self-sustaining wheat-to-Zombie-Power pipeline thus permanently resolves your late-game engineering bottlenecks.
