Fuel Array

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

The Fuel Array 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.

Falling below 50% of your max health will activate the Fuel Array which starts a short timer, ending with an explosion that is very likely to kill the player. It deals damage equal to 150% of the player's max health to themself, and 300% of their max health to enemies in a 30 meter radius. The selfdamage can be reduced with armor, allowing you to easily survive it as mult by using transport mode. Furthermore invincibility frames, for example from mercenary's eviscerate, will block the self damage entirely.

Interacting with in the Abyssal Depths stage with Fuel Array in the player's equipment slot will unlock REX as a playable character. This will also remove the Fuel Array from the player, as well as unlock the Power Plant challenge.
