Last War HQ Upgrade Requirements & Costs (HQ 1–35 & Oil)
Every Headquarters (HQ) upgrade in Last War: Survival requires upgrading your Tech Center to the current HQ level plus one rotating secondary building (Tank/Aircraft/Missile Center, Barracks on Lv. 20/24/27/30, Wall, Hospital, Alliance Center, or Drill Ground). Starting at HQ 31 through HQ 35, you must also unlock the Age of Oil research tree and spend Oil alongside Iron, Food, and Gold.
- The Mandatory Tech Center Rule: Tech Center is a required prerequisite for every single Headquarters level from HQ 15 to HQ 35.
- Key Troop Tier Unlock Levels: HQ 20 + Barracks 20 = T7 Troops · HQ 24 + Barracks 24 = T8 Troops · HQ 27 + Barracks 27 = T9 Troops · HQ 30 + Tech Center 30 + Barracks 30 + Special Forces Tree = T10 Troops.
- HQ 31 to HQ 35 (Age of Oil): Requires completing the Age of Oil tech tree to construct Oil Wells and level your buildings beyond Lv. 30.

Last War HQ 31 to HQ 35 Requirements (Age of Oil Endgame)
To push past HQ 30 into HQ 31–35, your server must reach the Age of Oil expansion (post-Season 2/3) and you must finish the prerequisite nodes in the Age of Oil tech tree to unlock Oil Wells. Each level from HQ 31 to HQ 35 raises your hero level cap by 5 levels (from Lv. 150 at HQ 30 up to Lv. 175 at HQ 35) and requires millions of Oil in addition to 1.3B–2.8B Iron/Food and 520M–1.2B Gold per level.
Last War: Survival: Optimal Meta Play vs. Common Resource Traps
- ●Stop upper Special Forces tech nodes at Level 4/10 (40%) so you save Gold for the bottom 4 nodes (HP, ATK, DEF, Unit X) to unlock T10 troops (~10.4B Gold total).
- ●Run 5 heroes of the same faction (5 Tank, 5 Aircraft, or 5 Missile) for the full +20% HP/ATK/DEF formation bonus.
- ●Sync all Radar tasks (Mon), HQ upgrades (Tue), Valor tech (Wed), Hero tickets (Thu), and Troop promotions (Fri) with the 02:00 UTC Alliance Duel VS reset.
- ●Do not max upper Special Forces branches to 10/10 before unlocking T10—it wastes billions of Gold and delays Unit X by months.
- ●Do not put Railgun or Data Chip priority on frontline tanks (Williams/Murphy); craft Radar and Armor for your front row first.
- ●Never open wrapped HQ gift boxes before Tuesday 02:00 UTC (Base Expansion) or Drone Component Chests before Wednesday 02:00 UTC (Age of Science).
