HQ Progression Speedrun: The Ultimate Path to Level 30
In Last Z: Survival Shooter, your Headquarters (HQ) level dictates your overall potential. Higher HQ levels unlock stronger troops (T9/T10), advanced research, and dominant heroes. This speedrun guide focuses on the "Minimum Requirement" strategy—upgrading only what is necessary to hit the next HQ level as fast as possible.
Phase 1: The Foundation (Levels 1-15)
The early game is about rapid expansion. Resource costs are low, and building times are short. Use this phase to join a top alliance like BLNW to maximize "Alliance Help" time reductions.
- Focus: Radar missions and clearing base blocks.
- Key Bottleneck: Wall Durability and Warehouse capacity.
Phase 2: The Mid-Game Grind (Levels 16-25)
This is where the game slows down. Building times jump from hours to days. Strategic use of Speed-ups and Diamonds is vital here.
| HQ Level | Primary Requirement | Secondary Requirement |
|---|---|---|
| 17 | Wall Lv. 16 | Warehouse Lv. 16 |
| 19 | Wall Lv. 18 | Laboratory Lv. 18 |
| 22 | Wall Lv. 21 | Alliance Center Lv. 21 |
| 25 | Wall Lv. 24 | Rally Square Lv. 24 |
Pro Strategy: The "Research License" Rush
At HQ Level 18, you unlock Lab No. 2. This is a game-changer. Ensure you have saved enough currency to buy the Research License immediately. Doubling your research speed is mandatory for a successful speedrun.
Phase 3: The Path to T10 (Levels 26-30)
Reaching Level 30 is the ultimate goal. At this stage, your City Walls and Alliance Center will be your main obstacles. The resource costs for Steel and Fuel become massive.
- Tactic: Participate in all State Assessments to earn universal speed-ups.
- Resource Shielding: Keep your resources in your bag (items) until the very moment you start the upgrade.
Summary Checklist for Fast Progression
- Always Help: Click the "Help" icon for your alliance members—they will do the same for you.
- Laboratory Sync: Always keep your Laboratory level equal to your HQ to unlock higher-tier troops immediately.
- Secondary Builder: Always have the second builder active (hire with diamonds or permanent purchase) to work on prerequisites like Walls while the HQ is upgrading.
HQ Progression FAQ
A: No. Upgrade them only when they are required for the HQ or if you need to unlock a new troop tier (e.g., Level 26 for T9). Speedrunning is about the HQ first.
A: Focus your Radar missions on high-level resource tiles and participate in Alliance Rallies against Tyrants for massive rewards.
A: Only during "Building Events" to secure top rankings. Otherwise, save Diamonds for VIP points or Hero recruitments.
