Quick answer
If you are searching for Star Wars Zero Company base building, the confirmed system to understand first is The Den. Official sources describe The Den as Zero Company's home base on the Ring of Kafrene, where Hawks returns between missions to plan, recruit, outfit Operators, treat injuries, upgrade facilities, and prepare for the next operation.
Is it freeform base building?
Do not assume freeform room placement, decorative construction, hidden buildings, or a player-designed base layout. The official material presents The Den as a Command Center and campaign-management hub with upgradeable facilities and strategic choices. Until the live game is audited in detail, treat 'base building' as base management.
The Den and the campaign cycle
At the Holotable, Hawks chooses Operations and Tactical Missions available in the current Cycle. StarWars.com says Operations spend Intel and can reward items, Credits, and Influence, while missions advance the campaign cycle. Steam's official launch FAQ says Operations and Tactical Missions can expire and that story-critical missions become obligatory after a period of time.
Command Center facilities
The official Steam overview describes the Den's Command Center facilities as Holotable, Recruitment, Personnel, Armory, Upgrade, Medbay, Customization, and Memorial. That supports a single canonical base-building page now, with possible subpages later only if live-game evidence shows enough verified depth.
Upgrades and roster growth
The Upgrade Facility can fund improvements to existing Den infrastructure and roster-wide combat upgrades. Official examples include adding a Droid Bay for Astromech Custom Operators and weapon upgrades that improve Operators. The official Q&A also says the Operator limit starts at 7, has a current limit of 20, and can increase through Den upgrades, story progression, and new Authored Operators.
Recruitment, Personnel, and Bonds
Recruitment brings in Custom Operators, while Personnel covers Operator stats, the Focus Tree, Bonds, and changing most Operators' Specializations. Bonds can grow through missions, Operations, and Call for Backup, then unlock Cross Training benefits. This is a relationship and combat-support system, not evidence of romance routes.
Armory, Medbay, and Customization
The Armory handles default weapons, Weapon Modifications, Utilities, the Black Market, and weapon cosmetics. The Medbay handles recovery from injuries. The Customization Facility lets you update Operator appearance and outfits, while the Memorial records fallen Operators. Keep exact costs, timers, and upgrade sequences out of public advice until they are checked in-game.
What not to claim yet
Do not publish a best upgrade order, resource-cost table, full upgrade tree, hidden room list, build-slot optimization route, or perfect one-run map plan until live-game data is stable. This page should capture base-building searches while staying grounded in confirmed Den systems.
