Group Play with
Your Party

Create a party lobby, invite up to 4 friends, pick a legacy season, and hit Group Play. Every party member's game launches at the same time on the same patch version — no more "wait, which one are you on?"

Party invites show up as live notifications in the launcher sidebar. Join directly from the Party tab even without an invite if you just want to hang in the lobby first.
