Figure out which Orbitals mode to use so you and a partner can actually play. Stop mixing up the free local demo with the full Friend Pass. They are not the same thing. The free app dropping on the eShop at launch does two jobs. Do not treat them as one.

1Pick the Mode That Matches Your Hardware

SituationWhat to useWhat you get
Same room, one Switch 2, two controllersFull game or Friend Pass demoLocal split-screen. Demo equals opening chapter only.
Same room, second person has Switch 1, Lite, or OLEDLocal GameShare (owner has Switch 2 plus the game)Play together locally. GameShare can reach older Switch hardware.
Different houses, only one of you owns the gameOwner invites into Global Friend Pass or Online GameShareFull campaign. Still split-screen on each console. NSO required for both.

2Step-by-Step

3How to Choose Correctly

Same sofa, testing first
Friend Pass demo
Not the invite. The invite is online-only and needs an owner.
Same sofa, committing to the campaign
Buy one copy. Skip the app
No Friend Pass needed for local full game.
Long distance, one wallet
Friend Pass invite or Online GameShare
Same result: full game, split-screen, NSO.
Want each person to have a full unsplit screen online
That is not how it works
Devs confirmed GameShare and Friend Pass stay split-screen. Players already called that a downside on handheld.
