Choose your session
Select where your group will play. The result appears directly below the controls.
Use one system and Custom Battle for up to four local participants. Connect separate controllers and check who controls each monster.
Check the online limit before buying
The Japanese Switch 2 review reports two-player online matches and no crossplay. Store descriptions and broader online-player labels can leave the actual mode ambiguous, so use the specific platform’s current menu and latest announcements to confirm a planned purchase.
For friends with different console versions, budget for a same-system local session unless an official current update explicitly establishes the combination you need. Switch 2 hands-on review.
Steam lists Online PvP, shared/split-screen PvP and Remote Play Together. Those labels describe different ways to connect. They provide no cross-platform matchmaking guarantee. Steam feature listing.
Prepare a local match
Open Custom Battle, connect each controller and check separate control of each participant. Decide whether the session is for progression or immediate roster access before choosing the rules. For the full-roster option, follow Tournament Mode.
If you need Beyond the Boundary progress, check the visible Melee rule and the full Complete city name. Use the two-city checklist.
Use Steam’s local-session streaming option
A Steam host can start a local multiplayer session and invite friends using Steam’s Remote Play Together interface. Check that each player has a separate input assignment, then test movement before starting a serious match. The host runs the game and its local save. Connection quality and input behavior need checking for your own group.
This site has checked the listed feature and provides the setup decision. We have not run a multiplayer session or measured streaming latency. Steam’s Remote Play Together documentation.
Choose a fighter with the roster selector once the session is ready.
