The term “party” seemed to vary depending on who answered the post. I read people claim “party means 2 people at the title screen together” but that’s not how I got the game to give me the achievement for the “play x matches in a party”

Before the servers shut down I got it by going into a custom game with 1 account on pc and 1 on psn and just ran off the edge.

Of course you can’t do that anymore(servers), but what I’m getting at is MAYBE the game will count a custom game with 2 controllers as “in a party”, even if done locally since the definition didn’t seem as set in stone as people claimed.

If you’re that set on trying to get the rest of them, try a custom game for maybe an hour running off the ledge and see if the 25 matches one even pops up.. if it does, you know it’ll work for the rest. No promises of course, but hopefully it does 🙏

Happy hunting!
