Base Upgrades

Versioning

This article could contain outdated information that is inaccurate for the current version (1.52) of the game. It was last updated for 0.45.

Base Upgrades can be unlocked to enable new functionality at their base, nearby Structures, and connected Trench/Bunkers. Upgrades are automatically unlocked over time, at a rate determined by the amount of player activity at this base. Player activity is primarily determined by the number of players that have this as their Home or Forward Base. Player activity is also influenced by supplying the base and building structures nearby, especially in friendly territory.

Players can also choose to prioritize one Upgrade over another by clicking on it. The Upgrade that is prioritized by the most players progresses the fastest.

Some Upgrades require Infrastructure, which is provided by building Infrastructure Modifications in Bunkers. This applies only to Bunker Bases.
