Co-op on wilds.ai works two ways, and both start from one place. Open **Together** in the sidebar (or run `/lfg` in the Discord) to post a "looking for group". Friends join from either surface and everyone lands in the same room. Narrative, TTRPG, and dungeon-crawler worlds run one shared AI session that you truly play together. Arcade, retro, roguelike, and other real-time worlds become a play-together room: you each play your own run, race the same leaderboard, and talk it out in voice.Co-op on wilds.ai works two ways, and both start from one place.

#The two co-op modes

Not every world plays "together" the same way, so co-op is honest about which mode a world supports. The mode shows on every group card and in the room.

• 🟢 Shared session. One world, one AI narrator, everyone acting into the same story in real time, with voice. This is how narrative, TTRPG, and dungeon-crawler worlds play. See Multiplayer and co-op sessions for the in-session mechanics (turn modes, host controls, out-of-character chat).
• 🎙️ Play together. Arcade, retro/emulator, roguelike, platformer, racing, survival, 3D, strategy, and board-game worlds run as deterministic engines on each player's own device, so there is no shared frame-by-frame state to synchronize. Co-op for those is a play-together room: same world, same leaderboard, voice chat, but each player has their own run.

Some play-together worlds also add shared-world surfaces on top of the room. Wild Stars, for example, uses one default procedural star map for every commander and adds Galaxy Commons: persistent commander presence, galaxy chat, live heartbeat details, and major turn milestones over each player's own 4X run.

#Find or post a group on the site

1. Open Together in the sidebar and pick the Co-op tab (/app/together?tab=coop).
2. Browse the open groups. Each card shows the world, the mode badge, how many players are in, and the genre.
3. Tap Join on any open group, or Create group to post your own.
4. When you create, search for a world (or just describe a genre), pick how many players you want, and add a note (time zone, vibe, session length).
5. When the group is ready, everyone is routed into the room together.

#Matchmake from Discord

Run /lfg in the Discord and pick a world (start typing to search) or describe a genre. Wilo posts a group card with Join / Leave / Start now / Cancel buttons. Anyone who taps Join is in the same group as the website players. When the group fills (or the host taps Start), Wilo DMs everyone the room link.

#What happens when a group is ready

Both modes land everyone in a room with the world, the players, and the launch + voice options.

• Shared session: the host opens the world and starts the co-op session; everyone else joins from the invite link.
• Play together: everyone opens the world and plays their own run, then compares scores on the world's leaderboard. Worlds with a shared-world layer may also show a persistent in-game commons for presence and chat.

Inside the room, the Who's here roster badges every participant: you, friends, other players, guests, and any characters brought along, credited to their owner. The room also carries its own invite block: copy the room link or invite friends and followers directly, and anyone who opens the link can join the group from the room. Play-together rooms include opt-in voice: tap Join voice in the room (or in your run's Playing Together panel) to talk, and mute anyone per person once you're in.
