Direct answer
As checked on August 16, 2026, the current Steam and Xbox capability listings identify Sandustry as single-player. The reviewed evidence did not contain a verified official multiplayer roadmap announcement. That describes the current evidence; it is not a promise that multiplayer can never be added.
Field note
Read the current store capabilities
Check the live Steam and Xbox product pages for feature labels rather than relying on an old FAQ or video title. Platform listings can change as Early Access development continues.
The checked pages support single-player and do not provide the evidence needed to publish co-op setup instructions.
Field note
Distinguish absence from a permanent decision
No current multiplayer label and no verified roadmap statement mean the responsible answer is “not currently evidenced.” They do not support claims about every future version.
Treat developer announcements, patch notes, and updated store capabilities as the triggers for changing this page.
Field note
Avoid mod and community confusion
A community experiment, conceptual mod, shared save, or remote-control workaround is not an official multiplayer mode. Label such material separately and verify version, safety, and actual player interaction before describing it.
If the store later adds co-op or multiplayer capabilities, refresh platform scope, player count, hosting, save behavior, and cross-play as separate facts.
