Multiplayer, crossplay, and save modes

Steam lists single-player, multiplayer, co-op, online co-op, and cross-platform multiplayer. The store line is up to three friends, which is one host plus three, four people in the session. There is no shared-screen or split-screen category. A couch-co-op search is aimed at a mode the store does not claim.

Shared saves arrived with Greater Cause on 29 September 2025. You can keep up to ten shared saves. A session still caps at four people, though more than four can hold access to the same save. Only one person hosts at a time. Progress syncs through the cloud. If the last holder deletes the save, it is gone. A standard save can be hosted in solo or co-op, but only by its creator. Standard and shared saves can be copied into each other.

Crossplay in the store categories is real for the platforms that exist. Those are Steam and Xbox. There is no PlayStation or Switch build, so there is no crossplay with them. A marked developer reply on Steam in December 2023 said there were no current plans for dedicated servers. The 1.0 notes do not add one. If you cannot connect, the checks I will write are: the host is online, both sides are on the same version, and nobody else is already hosting that shared save.
