So you already know Guitar Hero II is coming to Xbox 360. By way of logical extension, you then probably already know the tracklist, the hidden songs and all the reasons why the series is one of the best-selling music games of all time. Hell, it's one of the best games around, period. But if you're such a huge fan already, why bother getting it again on 360?

New songs are a given. We've got the list coming up in a second. Downloadable content is on the way. There's the new X-Plorer controller too, though so far we've gotta say the standard PS2 one feels better. What's left then? Achievement Points out the ass. Look below the screen for the complete list, then click on over to the next page for a rundown of new, exclusive 360 songs.

We especially like the "Start a Real Band Already" award, plus the shout-outs to great musical duos of our time ("Lennon and McCartney" is yours when you get an 8x Multiplier in a co-op game, for example). There are also cool little bonuses like failing a song on easy and refusing to play an encore. Read on:
