Get a second player into WheelMates for the full 2-player campaign without buying a second copy. Players on Steam keep hitting the same wall: the second person searches the wrong product, launches Friend Pass alone, or expects the old demo to still work as a standalone game.

1Online (one purchase plus Friend Pass)

If you have no partner, people are posting need a partner in Steam discussions and the official Discord mentioned in community posts.

2Same Couch (no Friend Pass needed)

Local play is what players use when online invite or desync is messy. Reports say local split-screen is unaffected by the online desync talk.

3Decision Points

Online long-distance
One purchase plus Friend Pass
This is the whole point of the feature.
Same room, one PC
Skip Friend Pass, use split-screen
Two controllers on one machine.
Same room, two PCs
Treat it like online
One full copy, one Friend Pass.
Family Sharing vs Friend Pass
Use Friend Pass for a second Steam account
Do not assume Family Sharing replaces the pass. There is already a Steam thread about people mixing the two.
Who should own it if you later split up
The person who wants to keep inviting other friends
One owner can invite different Friend Pass players over time, one at a time.
Remote Play Together
Not the official free-join path
Players are asking for it. The supported free path is Friend Pass.
