Gearhead Boss is one of the 54 Collector Cards in RAGE to be played in the minigame Rage Frenzy.
Location[]
The card is found in the Power Plant. After the player has made it all the way through and killed the boss, they'll end up on a platform with some kill switches. After playing around with those until the Gearheads are dead and then leaving through the open door, it's through the doorway on the left and up the stairs. The player will find the card on a file cabinet unit.
