Supports are unit types that you link to your survivors to gain active abilities to use in combat.

In combat
The supports' range, visibility and damage depends on the survivor they are linked to. Support abilities can only be used once per turn, and any kills made from Support abilities do NOT grant your survivors charge points.

Unlocking & leveling
You can unlock supports by getting support tokens via leaderboard rewards of the game mode Last Stand, as well as from the Survival Pass. To level up and improve the supports abilities, you will also need the same support tokens.

Supports are viewed in the 'Survivors' menu, under the 'Supports' tab.
