Major Update 6 (Co-op)
Major Update 6 was the co-op-focused milestone before 1.0, refining online sessions, Vice-Mayor permissions, split-screen behavior, and sync issues reported during Early Access couch playtests. If your last session predates MU6, expect different permission menus and more stable four-player PC hosting. This page contextualizes MU6 for returning mayors and wiki co-op guides written against 1.0.
Co-op improvements
Expanded permission toggles for EGO, demolition, and land unlock. Better handling of mixed local and online players on PC where supported.
Emote and ping reliability tweaks for coordination without voice chat.
Split-screen
Switch split-screen layout and performance passes preparing for retail Switch launch in 1.0.
See co-op/local-co-op for current setup steps.
Pre-1.0 bridge
MU6 did not include Creative Mode — that arrived in 1.0. Desert and cave content from earlier major updates remain unchanged in core layout but may have balance patches bundled in 1.0 hotfixes.
Wiki relevance
All co-op hub pages assume MU6 or later permission model. Report outdated steps via community channels if 1.0 hotfixes change menus.
