Progression#
Almost everything in Last Z runs along one spine: your Headquarters (HQ) level. Raising the HQ unlocks the rest of the base.
The HQ gates everything#
- Hero level cap = HQ × 5. An HQ at the cap of 35 lets heroes reach level 175.
- Buildings unlock by HQ level — e.g. Radar at HQ 3, Laboratory at HQ 7, Toxic Fog Garden at HQ 8, Trade Center at HQ 9, Dawn Tower at HQ 11, Steel Factory at HQ 14.
- Troop tiers carry an HQ-level requirement on top of camp level (Tier 3 at HQ 10, Tier 4 at HQ 20, Tier 6 at HQ 30).
- The HQ itself needs the City Walls to upgrade, and the Military Center for the HQ 6 step.
Pacing#
The earliest HQ levels ramp faster than later ones. Hero EXP (from the Training Ground) and Zent (Residence + Wanderer's Camp) feed hero leveling and research — earned from those buildings, or bought outright as Super Supplies weekly passes. See Resources & Economy.
