Activision is offering a demo of Guitar Hero: Greatest Hits (Smash Hits in the US) to everybody on Xbox Live - including Silver subscribers.
The sampler weighs 498MB and has three songs - "Rock and Roll All Night" by KISS, "Take Me Out" by Franz Ferdinand and "Woman" by Wolfmother - and one venue to play.
Guitar Hero: Greatest Hits complies all of the best songs from Guitar Hero I, II, Rocks the 80s and III. The idea is to spread them across the multiple Guitar Hero: World Tour instruments.
Guitar Hero: Greatest Hits arrives here for PS2, PS3, Wii and Xbox 360 on 26th June.
