Is Star Fox cross-platform?

Star Fox is exclusive to Nintendo Switch 2, so there is no cross-platform play; all multiplayer is Switch 2 to Switch 2. It does, however, have a robust multiplayer suite: a 4v4 online Battle Mode for up to eight players (Team Star Fox vs. Team Star Wolf) across stages such as Corneria, Fichina and Sector Y, plus a story co-op mode where two players split a Joy-Con pair as Pilot and Gunner locally or online. GameShare lets friends without their own copy join a session, and GameChat supports voice and camera chat. A Nintendo Switch Online membership is required for online play, but not for local or GameShare sessions.
