Direct answer
The public Roblox game record lists a maximum of six players per server. It does not document co-op, PvP, cross-play, or matchmaking rules.
Build a Dinosaur multiplayer
The official public Roblox game record lists maxPlayers: 6 for this experience. That documents the server cap, not a co-op mode, PvP, cross-play, cross-progression, matchmaking, or private-server policy.
Confirmed access context
Build a Dinosaur is listed on Roblox and has a public six-player server cap. The checked metadata does not describe how those players cooperate or compete.
Modes still unknown
- Local or online co-op support remains unknown without an explicit checked source.
- Cross-play and cross-progression are not treated as the same feature and are not inferred from shared storefronts.
- Server region, matchmaking, private lobbies, voice chat, and subscription requirements stay unconfirmed until documented.
What to check next
Use the official listing and update page for mode announcements. This tracker changes only when the source ledger contains an eligible statement, so an absence of confirmation never becomes a fabricated feature list.
