Free-to-play co-op shooter Once Human launches today on PC, iOS, and Android. The game has cross-play, meaning you can play with your friends regardless of what platform they are on. However, cross-progression has some limitations. If you make an account through Steam, for example, you can't transfer your character from Steam to iOS or Android or even to another PC storefront.

A launch Q&A on the game's Steam page clarifies how cross-play works. The gist is that every platform has access to the same servers. As long as you are on the same server as your friends, you can play with them. It doesn't matter whether you are on Steam, Epic, mobile, or the Once Human launch client "Loading Bay."

The same Q&A explains cross-progression limitations, though the wording is confusing. Because of "their inherent limitations," some account types like Steam cannot use their account or character on another platform. Starry Studio didn't name any other platforms, so it's worth checking with your preferred platform before diving in. If you want to play across PC and mobile, the best bet is to download Loading Bay. The Q&A also promised that more account options are on the way, though it stopped short of mentioning console versions or changes to existing account types.
