An Audiosurf update was released last night. This update doesn't include fixes or new game modes, it simply adds on six new achievements that you can earn.
- Brutus: Dethrone a friend from a global scoreboard
- Ambush: Beat a friend's score less than 15 min. after they earn it
- Olympian: Earn triple a gold medal requirement. 2 min minimum
- Bauer: Collect a match of 24 blocks
- Ninjutsu: Stealth and collect every color block. 3 min minimum
- Bizarro: Fill all columns within 15 seconds. No greys. No matches
