Last Z Base Building Order — Shelter Progression Guide
Quick Answer
Base building order in Last Z prioritizes Headquarters (which caps hero and building levels), then the Laboratory + rotating HQ prerequisites, while keeping food/wood/electricity production steady and pushing shooter stages for rewards and hero XP.
Key insight: Laboratory is mandatory from HQ8 onward, so plan HQ upgrades around Lab + prerequisite building cycles.
Shelter Progression Order (Core Loop)
Step 1: Prioritize Headquarters (HQ)
Headquarters upgrades unlock buildings and set the maximum level for both heroes and buildings, making HQ the main progression bottleneck.
See the full requirements and checkpoints in the HQ Upgrade Guide.
Step 2: Track HQ Prerequisites (Lab + Cycle)
From HQ8 onward, Laboratory is always required, plus a second prerequisite that rotates through City Walls, Alliance Center, and the three Camps (Assaulter, Shooter, Rider). Keep these buildings close to HQ level to avoid hard blocks.
The Laboratory itself unlocks at HQ7 and is required to research technologies.
Step 3: Keep Core Resource Buildings Running
Food, wood, and electricity power construction, upgrades, and troop training. Farmhouse produces Food, Lumberyard produces Wood, and Wind Turbine produces Electricity. Keep them upgraded enough to avoid resource bottlenecks.
Use the Resources Guide to balance gathering and production.
Step 4: Push Shooter Stages for Rewards and Hero XP
Shooter stages provide rewards and XP crates that level heroes, and both modes feed into each other for long-term progression.
If you want a dedicated breakdown, see Shooter Stages Guide.
Step 5: Advanced Building Priorities (Community Meta)
Experienced players prioritize Lab, Camps, Military Center, City Walls, and Formation along with HQ. They also recommend raising Production Center, Alliance Center, Villa, Bookstore, Rally Square, and Formations to functional levels before over-investing in resource buildings.
Advanced Tips & Common Pitfalls
- Lab is mandatory: From HQ8 onward, Laboratory is always required for HQ upgrades.
- Follow the cycle: City Walls → Alliance Center → Assaulter → Shooter → Rider repeats as the second prerequisite building.
- Production Center matters: It increases gathering speed and troop load, helping both economy and marches.
- Trade Center is niche: It boosts Zent production but is generally lower priority early on.
- Lab No. 2 is optional: A second Laboratory unlocks at HQ18 but requires a Research License.
