Building tech tree
Linear unlock progression for Theatre Compound structures. Command HQ and Training Yard start at Lv1; read top to bottom for everything else. Later rows need higher prerequisite levels across your base. Your compound only shows pads you can construct or have already built.
How progression works
- Every structure has a fixed pad on your Theatre Compound. Pads stay hidden until you meet the first-build requirements shown below.
- Command HQ and Training Yard are pre-built at Lv1 on every new base. The Training Yard recruits operatives and never requires operatives to staff its own upgrades.
- Command HQ produces capital and boosts other production — upgrade it and add Logistics Yard / Warehouse early to fund the rest of the tree.
- The first level of a building uses Construct; later levels use Upgrade.
- Rows are ordered by how far along you need to be — prerequisite building levels count, not just how many structures sit between you and the goal.
- Some milestones unlock multiple branches at once (e.g. Warehouse Lv3 + Barracks Lv3 gates Armoury; Barracks Lv10 + Training Yard Lv10 + Armoury Lv8 gates Special Ops Compound).
