Building Upgrades

DIRECT ANSWER

Building Upgrades: current answer

Check a building upgrade's actual unlock separately from its interface. AG-27 improves upgrade feedback, ST-11 gives Level 2 Resource Transfer Stations drones, and ST-24 removes Level 2 as a requirement for basic Warehouse transport.

Quick facts

  • AG-27 improves interaction feedback and clarity for upgradable buildings.
  • A Level 2 Resource Transfer Station unlocks hauling drones under ST-11.
  • ST-24 unlocks White-tier Recon Sniper and Grenade Launcher blueprints by default when the Weapon Research Center reaches Level 2.
  • Basic station-to-Warehouse hauling no longer requires Level 2 after ST-24.

Practical workflow — editorial guidance

Read the exact building name, current level and next-level unlock in the live interface before spending materials.

If upgrading to solve missing transport, distinguish basic Warehouse routing from the separate drone unlock.

For a missing blueprint, record the Weapon Research Center level and the blueprint tier instead of assuming every version of the weapon should be unlocked.

Evidence limits

This evidence does not provide upgrade material costs, build times or a complete level-by-level building database.
