According to GOG.com, the service will auto-update games in your GOG.com library, though the company stresses that you'll still be able to manually and apply patches if you prefer. Multiplayer games with a single-player component will be available for play offline, and Galaxy will also enable cross-play between services such as Steam, the developer said.
No release date is available for the service at press time, but the service was announced alongside The Witcher Adventure Game closed multiplayer-only beta. You can sign up for the service, and that beta, at the GOG Galaxy site .
