Street Fighter 6

Hey all me again! Head to battle mode and run all the way to the back right of the hub to the game center (or press and hold then press to fast travel to get to the places you want to go) once at the game center pick any arcade cabinet you like and press then Select High Score Challenge, once it starts you should get both (Classic Leaderboard Champ) & (Kickin' it Old School) achievements. Hope this helps, feel free to add me on SF6 to send a like my way in the game for the 600 achievements so I can update that achievement for progress on here for all the future world warriors of SF6 achievement hunting community. Thanks again!
