Factory Basement Unlock and Power Grid Limits
The subterranean factory floor represents the industrial heart of your mid-to-late game operations in Graveyard Keeper 2. Gaining access to this sprawling underground facility requires clearing the toxic sludge barrier blocking your cellar stairs and advancing mechanic Jack's storyline past his initial milestone contracts.
Every electrical mechanism and motorized conveyor belt installed on the factory floor draws from a shared municipal power grid. Early factory setups operate under a strict forty-unit power budget, which can subsequently be expanded to eighty units by mounting auxiliary dynamos along the northern power conduit walls.
Because each motorized belt tile consumes half a power unit and heavy assembly workbenches draw between three and five units, careless sprawl will swiftly cause breaker trips. Careful spatial planning and tight machine clustering are mandatory to prevent grid brownouts from halting your automated workforce.
Modular Three-Lane Design and Conveyor Routing
The most reliable organizational architecture for underground logistics is the parallel three-lane modular block. Rather than interweaving tangled conveyor loops across the chamber, divide the factory floor into three independent linear channels: carpentry processing, metal refining, and central component assembly.
Always maintain a clear one-tile transit corridor alongside every conveyor spine. This open walking space allows keepers to inspect workbench queues, manually clear unexpected debris, and guarantee unhindered zombie pathfinding between freight drop zones and sorting tables.
Direct all raw material delivery inputs from the surface elevator into dedicated filter splitters before routing them onto processing belts. Segregating incoming logs, iron chunks, and cut stone prevents cross-contamination jams that could paralyze your secondary assembly lines.
Automating Town Restoration Kits and Warehouses
The ultimate operational goal for a mature factory layout is autonomous fulfillment of weekly Town Restoration Kit contracts. As civil reconstruction expands, town merchants demand continuous shipments of Wooden Kits, Stone Kits, Iron Kits, and advanced Engineering Kits to restore damaged districts.
Configure your carpentry line to convert incoming logs into flitches and polished planks, directing half of the plank output into the kit assembly bay. Simultaneously, route smelted iron ingots through a dedicated splitter that feeds one line into nails and the second into complex iron brackets.
At the junction of both lines, place an automated packaging bench. Zombie workers stationed at this terminal combine planks, nails, and brackets into finished wooden and iron building kits, depositing completed crates directly into the outbound freight chute for effortless weekly gratitude rewards.
Zombie Worker Allocation and Anti-Jam Buffers
Unattended conveyor belts will inevitably back up if output processing speeds lag behind upstream fabrication. To neutralize potential bottlenecks, integrate high-capacity buffer chests between raw ingredient processors and secondary assembly benches to absorb sudden delivery surges.
Allocate your undead workforce based on specific organ proficiencies. Assign high-skull zombies equipped with smithing hammers and carpenter axes directly to the production tables where craft speed multipliers apply, while dedicating lower-tier, single-skull zombies strictly to freight hauling and chute transfer tasks.
