Everyone who wants to play needs their own copy of the game on Steam, running on a Windows PC. (No mobile version yet — see our mobile guide.) Once everyone's bought it and booted Steam, you're ready.
One person creates the room. It doesn't hugely matter who, but pick someone with a stable connection — they're effectively running the lobby. That person launches Meccha Chameleon and looks for the option to create / host a private room.
Once the room is created, the host gets a room code (a short string). Send that code to your group — group chat, Discord, whatever. This is the key everyone else uses to join.
You can also invite directly through Steam friends if everyone's added each other — sometimes faster than typing a code.
Each friend launches the game, picks join a room, and enters the code. They should pop into your lobby within seconds. Wait for the whole group before starting — once a round kicks off, late joiners may have to wait.
Meccha Chameleon splits the room into Hiders and Seekers. Hiders paint themselves to blend into the stage; Seekers try to spot the fakes. The host usually starts the round once everyone's in. That's it — go hide.
Once everyone's in the room, the real fun is in the strategy — and a smooth host keeps the energy up. Grab our free printable host & hide kit for a run-of-show, party-night checklist, and a quick-reference card. Then send your hiders to the hiding spots guide and your seekers to the seeker tips guide so nobody's guessing round one.
Yes — everyone joining a room needs their own copy of Meccha Chameleon on Steam. There's no free spectator or guest mode.
Host a private room in-game, then share the room code (or invite directly through Steam friends). Your friends enter the code to join.
Not natively. As a workaround, one PC owner can stream the game via Steam Link to a phone. See our crossplay guide for details.
Party hide-and-seek shines with a fuller lobby. Check the Steam store page for the exact player cap — aim for the upper end for the most fun.
