This collector's edition Performance Thumbstick was developed in collaboration with Infinity Ward for use in Call of Duty: Zombies. It was built for intense close-quarters combat typical of the game mode and is a must-have for Zombies fans. Revive! is the second thumbstick in our extremely limited edition Perk-a-Cola series after last year's Jugger-Nog. It was developed in collaboration with Call of Duty to meet the explicit demands of Call of Duty: Zombies and built to handle the intense hand-to-hand combat typical of the franchise. Based on the Perk-a-Cola soda bottle cap from Zombies, Revive! features a vintage blue color and a highly detailed rendering of the iconic beverage's logo stamped on our proprietary rubber pad. The laser-etched artwork and fluted bottle cap shape provides solid grip and comfort for long-lasting zombie survival. The 5.7mm of height added by Revive! creates a nearly seamless feel for those looking for big results but prefer less adjustment time.
