Lone Echo is a 2017 virtual reality adventure game developed by Ready At Dawn, and published by Oculus Studios. Set aboard a space station orbiting Saturn, it allows players to move in zero-gravity by grabbing and pushing off of the environment. In addition to the narrative single-player game, the title includes a team-based multiplayer sports mode called Echo Arena, which was also released as a stand-alone game. A sequel, Lone Echo II, was announced in 2018 and released on October 12, 2021.

Reality Labs, originally Oculus VR, is a business and research unit of Meta Platforms that produces virtual reality (VR) and augmented reality (AR) hardware and software, including virtual reality headsets such as Quest, and online platforms such as Horizon Worlds. In June 2022, several artificial intelligence (AI) initiatives that were previously a part of Meta AI were transitioned to Reality Labs. This also includes Meta's fundamental AI Research laboratory FAIR which is now part of the Reality Labs - Research (RLR) division.
