Zombie shelter & base management

Base building here means developing a compact underground refuge, improving the rooms that keep the next run possible. The Water & Hydroponics room produces food and supports crop irrigation; the Generator supplies energy; the Research Lab generates research; the Ammo Press turns battlefield scrap into ammunition; and the Salvage Bench converts scrap into parts or ammunition. Each room can be upgraded, and an expansion bay can add a second generator, garden or salvage station.

Those systems compete for the same recovered materials. Scrap spent improving a room cannot also become ammunition or machine parts, while energy and food are needed to prepare another deployment. Storage has a ceiling too, so a production room that fills its store stops contributing until there is room again. Shelter management is a balancing act between immediate readiness and a stronger long-term base.

Residents are part of the production plan, not just faces in the shelter. Assign one resident to a room to increase its output; a person’s specialty adds another boost when they work at the matching station. Each resident can hold one work assignment at a time, so moving a specialist to the Lab means giving up that person’s help at the Generator, garden, Salvage Bench or Ammo Press.

The campaign data defines five women for the resident roster: Mara the mechanic, Iris the botanist, Sable the quartermaster, Jun the electrical engineer and Vera the radio researcher. Their specialties map to different shelter stations. The current demo gate makes Mara playable; the other four are not available in the demo. Residents can train and build relationships through conversations as campaign access allows.

Food production links the base economy to a hands-on hydroponics system. Crops grow on a timer, with progress shaped by available irrigation and stored water. Lettuce, tomatoes and roses serve different needs: harvests can refill food stores, support recovery or provide a small relationship gift. Tending an unfinished crop costs stored water and improves its harvest. More farm racks add plots, while purifiers raise irrigation supply.

Growing remains a resource choice. Hydroponics needs enough irrigation to maintain full crop speed, and a growing colony consumes food over time. A full pantry or low water supply can interrupt the plan. This gives the underground base its own rhythm between deployments: check the plots, decide what to plant next, and make sure the food line can support both residents and the next trip outside.

Research from the Lab opens a branching technology tree across Shelter, Industry, Defense and Arsenal. Early investments can expand storage, increase passive production or improve battle health. Prerequisites then lead toward more focused plans: strengthen supply logistics, unlock a machine shop and crafting options, reduce losses after defeat, or shape weapon performance for a preferred combat style.

Some later doctrines are mutually exclusive pairs. For example, a shelter can prioritize stronger food and energy production or better expedition salvage returns; the Industry branch can favor cheaper crafting or faster scrap processing; and Arsenal choices trade firepower against speed, range or magazine size. The decision is permanent in the save, so research is a build path rather than a checklist to complete in every direction.

Deployments supply the resources that keep the shelter moving. Sector victories, salvage expeditions and scavenging runs settle different rewards, but they all feed the decision about what to improve next. A defeat can levy a bounded amount from exposed supplies and set back sector progress; the base, its residents and permanent upgrades remain. That persistence gives survival runs a longer arc than the result screen alone.

Production accrues with elapsed time, including while away, but only through a capped window: eight base hours, plus two hours per Night Shift rank and four hours from Seed Vault, for an 18-hour maximum. Storage, available scrap and active production orders still constrain the result: presses stop when their input runs out or their output store is full. The shelter rewards planning between sessions while leaving scavenging and zombie combat as active play.
