upgrading your HQ & Tank

Headquarters

The Headquarters is the main building in your base in Last Z Shooter. Upgrading it unlocks new features, higher building levels, new hero levels, and more, helping you grow in power.

However, each HQ upgrade has specific building requirements that you need to meet first. The table below lists the required buildings for each HQ level.

From HQ level 8 onward, the Laboratory is always required for upgrades. The second required building follows a set cycle: City Walls → Alliance Center → Assaulter Camp → Shooter Camp → Rider Camp, repeating in this order.
