Reclaiming buildings
The field reference. Know what you’re working with.
five sites, fifteen possibilities
Each expedition chooses five building types from a pool of fifteen. Buildings have regional appearances and remain repaired between waves. Explore the whole map to find them.
stand in the service circle
Repair and upgrade automatically while inside the circle. Each visit buys at most one rank; leave the circle and return to buy another. Moving away pauses unfinished progress; taking damage does not erase it. Return when you have breathing room. Building ranks unlock at waves 1, 5, 10, 21, 26 and 31.
local and global rewards
Every active building produces scrap every 20 combat seconds. Its permanent stat bonus works throughout the district; its support effect works nearby. Building Power improves output. Bring all five online to activate your district's defensive network. See Buildings for exact rank previews.
