got a new psp yesterday and got rock band unplugged.

now obviously you cant connect the drums, guitar or even a mic so how do you play?

you play as the whole band!! you have 4 highways that you cycle through with the L&R triggers, its hard to explain but basically for each instrument to stay in green you have to hit a certain amount of notes then a score pops up and you can move to a different highway, you can choose any of the 4 highways at any time and play any of the notes.

sounds confusing but its really damn addictive
