deeproot Pinball, founded in 2017 in San Antonio, Texas by Attorney and Entrepreneur Robert J. Mueller, was launched as an ambitious pinball manufacturer and startup that sought to reinvent modern pinball machines by assembling veteran designers including John Popadiuk and promising innovative features such as a “PinBar” touchscreen integrated into the lockbar of its flagship title Retro Atomic Zombie Adventureland (RAZA); the company unveiled prototypes and opened pre-orders in late 2020 but never completed mass production or delivered commercial machines, leaving only a small number of prototypes and a legacy as a high-profile failed pinball venture. The company generated strong early interest among pinball enthusiasts for its aesthetics, design team, and the Retro Atomic Zombie Adventureland theme, but legal and financial troubles followed: the U.S. Securities and Exchange Commission filed a civil enforcement action in August 2021 alleging misappropriation of investor funds related to deeproot’s affiliated funds, and deeproot Pinball ceased operations with assets later liquidated in bankruptcy proceedings, ending its plans to manufacture pinball machines at scale.
