In this encounter, the Warrior will find forty small, transparent mechanical bunnies with microfusion cells in their inventory roaming around a deserted plain. There is nothing of note to be found or picked up.
This encounter does not have a proper name on the main map, yet appears as a smaller green circle like the rest of the special encounters.
The bunnies are not visible, but are displayed as gray dots on the map.
It is possible to kill the bunnies by using explosive weapons, such as frag grenades or rockets. Any burst weapon also works. Despite not being visible, they can be shot at if any team member is set on overwatch. This greatly reduces the Warrior's standing in the Brotherhood of Steel, however.
Upon re-entering the special encounter, player might find himself unable to leave due to possibly bugged exit grid (like several other encounters)
Behind the scenes
This is a reference to the mascot of Energizer batteries, the Energizer Bunny, and to the original name of the company that manufactures Energizer batteries, Eveready.
