Humidifier Farming Route

Humidifier Farming Route

Stage 4/6 Outfitting needs five Humidifiers. This loop prioritizes Buried City’s Red Tower lockers with a quick Metro extract, with Dam Battlegrounds as a low-traffic backup.

Need: 5x Humidifier – Expedition Project 4/6 Outfitting
  • Breach the Red Tower third floor and loot the two red lockers; one often guarantees a Humidifier if uncontested.
  • If the lobby is picked clean, rotate to Pale Apartments and Ruby Residence on Dam Battlegrounds for quieter residential spawns.
  • Use the Metro extraction beside Red Tower to reset runs in under three minutes.
Lightbulbs for Framework
FarmingElectrical Loot Zones

Dec 7, 2025

Lightbulbs for Framework

Lightbulbs are electrical loot for Expedition 3/6 – Framework. Focus electrical zones and chain short clears to stack five quickly.

Need: 5x Lightbulbs – Expedition Project 3/6 Framework
  • Hit Spaceport maintenance tunnels and Dam Research/Admin blocks where electrical containers cluster.
  • Prioritize lockers, tool cabinets, and power rooms; skip low-yield residential shelves.
  • Pair these runs with Cooling Fan or Sensor routes to finish multiple Expedition steps together.
Cooling Fan Power Farm

Cooling Fan Power Farm

Cooling Fans gate Expedition Project Part 2. The fastest pulls come from tech-heavy buildings with stacked server racks.

Need: Cooling Fans – Expedition Project Part 2
  • Enter the Space Travel Building and sweep every server aisle and workbench for Technological loot.
  • Reset if the lobby is contested; fans are rarer than generic electronics, so clean spawns matter.
  • Use compact, lightweight loadouts to sprint extracts—fans are low weight, so bring extra stash space for side loot.
Cat Bed & Pillow Hunt
FarmingBuried City / Dam Battlegrounds

Dec 4, 2025

Cat Bed & Pillow Hunt

Scrappy upgrades need comfort items that only spawn in residential interiors. Buried City delivers the best density.

Need: Cat Beds & Very Comfortable Pillows – Scrappy upgrade
  • Run the Red Tower apartments in Buried City for back-to-back bedroom and lounge containers.
  • Check Dam Battlegrounds Testing Annex bedrooms when rotating for medical loot.
  • Clear every wardrobe, sofa table, and side cabinet—comfort items sit in generic residential props.
