Wall Upgrade Requirements

Wall Upgrade Requirements
Puzzles & Survival Guide

Last Updated: Feb 25th, 2022

The wall is an important building in your Sanctuary. Partly as it provides your defense against enemies destroying your base if you are attacked but possibly more importantly because it is the one building that you must keep upgrading in order to raise the level of your Headquarters.

We have a separate page with the Headquarters Upgrade Rewuirements but as the wall is needed for every one of those we have a list here for the wall upgrade requirements as well.

Please note that as with the headquarters the resource amounts will vary for you depending on the amount of research, talent points and other game boosts you are able to unlock in your game

The time specified in this list is the maximum time allocated by the game. Your own research and buffs will reduce this.
