HQ Levels

About the Headquarters in Last Z

Your Headquarters (HQ) is the central building that gates almost everything else — every other building's max level is locked to your current HQ tier, and most research, hero ascensions and event milestones require a minimum HQ level. Levelling HQ is therefore the single most important long-term grind in Last Z: Survival Shooter. There are 35 HQ tiers in total, and each one demands two specific building upgrades plus a resource cost.

What this table shows

For every HQ level from 1 to 35, the table lists:

• Required Buildings — the two structures you must upgrade to the same level before HQ can be upgraded. Late-game (HQ 31+) the requirement drops to a single building.
• Resource Costs — wood, food and zent (with steel added from HQ 31). Numbers are abbreviated (M = million, G = billion) and reflect the current live game values on Server 277.
• Heroes Cap — the maximum hero level you can ascend to. Heroes increase 5 levels per HQ tier, so HQ 30 = level 150 heroes.

Where the difficulty spikes

The early HQ levels (1–14) are designed to be cleared in your first day or two of play. HQ 15–19 is the “mid-early” phase where Builder Speedups become valuable. HQ 20 is the first major wall — resource costs jump 4× and the build time exceeds 24 hours without speedups. HQ 25 is the second wall (resource costs nearly 5× HQ 24). HQ 30 is the “current ceiling” for most active players. HQ 31–35 are stretch goals that require Steel, a late-game resource only produced by the Steel Mill (itself unlocked at HQ 31).

Strategy notes

Plan upgrades around resource caps — if a tier costs 1.4G food and your warehouse caps at 1G, you'll lose the overflow unless you collect, spend, and refill multiple times. Each tier's resource cost is shown in this table so you can pre-stage Speedups and resource items. The cheapest path through HQ 1–30 (in real-money terms) is to coast the early levels with farms / hand collection and save your Builder Speedups for the HQ 20+ walls where they'll save days of waiting.
