Update 4 is now live for Hi-Fi RUSH! This Update contains a few improvements for the game, detailed below:

• Removed exploit that allowed players to continuously resell attacks that the player has already sold. This adds realism since you cannot sell that which is no longer yours.
• Fixed an issue where the “Specialist” challenge on The Wall of Fame will not be unlocked despite purchasing all available Special Attacks in the game. (*Note: This is retroactive, so if you have already purchased the attacks it will register the objective as complete automatically*)
• Fixed an issue where a cool hidden animation for playing with 808 on the couch while she is equipped with the Bossplay Roquefort costume would not play.
• Fixed support of PSO caching on the Microsoft Store version which could cause hitching during gameplay.
• Adjusted couch pillow softness in the hideout to better refresh Chai when relaxing in between missions.
