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.

Unlike most other equipment, the Fuel Array cannot be activated normally. Instead, it automatically activates if the holder falls below 50% of their maximum health. When this happens, the Fuel Array triggers a 30m explosion that deals severe fixed damage after a short countdown; both the holder and any enemies in range are damaged for 300% of the holder's maximum health and suffer heavy knockback. This explosion has a proc coefficient of 0.0.

When the Fuel Array is activated and explodes, it is destroyed and removed from the player's inventory, regardless of any they have.

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.

Tips

 * The Fuel Array's explosion does not bypass one-shot protection, so it can theoretically be weaponized to deal massive area damage if the player's one-shot protection becomes active. This can only be done with large amounts of healing, however, since the player will need to recover at least 40% of their health before the Fuel Array explodes.
 * can make excellent use of the Fuel Array's volatile nature, as his will also have their own Fuel Arrays. While this does cut their lifespan short, they will explode when sufficiently damaged and inflict colossal damage on any enemies nearby.
 * This is especially effective when using Engineer's, which will charge straight towards enemies.
 * This strategy is much more feasible in multiplayer runs than singleplayer, as dying from the Fuel Array will not immediately end the run.
