Activision launches the Backstage with Guitar Hero space for PlayStation Home today.
Visitors can compete in a Guitar Hero-inspired multiplayer mini-game. It uses the PS3 controller's face buttons to reproduce a track played by the AI, but becomes steadily more complex and harder to remember each round.
Eventually, groups of buskers will be whittled down to one winner.
Local leaderboards will sort the wheat from the chaff, and, to mark the launch of the space, PlayStation Home community will compete and hand out prizes every hour tomorrow from 8pm GMT until the early hours of Saturday morning.
There's a video of the Backstage with Guitar Hero space on the US PlayStation blog.
