• New game mode, Solo Showdown: basically minigames where the bottom 4 are eliminated every round
• Dynamic Commentary (June and Scotty will read your username)
• UI and HUD updates (including a customizable quick settings panel accessible ingame)
• New Sponsor System (the third one... also anything you didn't earn from previous sponsors is lost forever)
• Better footsteps sounds
