Fuel Array

The Fuel Array is a single-use equipment in Risk of Rain 2, added in the Scorched Acres Update.

It can only be obtained during the first stage, by interacting with a hatch on the back of the Escape Pod that the player spawns from.

Activating the Fuel Array starts a short timer; when the countdown ends, it triggers a 30m explosion that deals severe fixed damage; the player takes 150% of their max health as damage and deals 300% of their max health to enemies. When this happens, the Fuel Array is destroyed and removed from the player's inventory, regardless of any they have.

Additionally, if the player ever falls below 50% of their max HP, the Fuel Array automatically activates.

The main purpose of the Fuel Array is for repairing the broken robot in. If the player interacts with the robot while they have a Fuel Array equipped, it will clear the Power Plant challenge and unlock as a playable Survivor. This will also remove the Fuel Array from the player's inventory.
