If you elect to go the refund route, you have to put in a little leg work. Fill out this form (a PDF file), then stuff it in a box along with your guitar controller, guitar strap, and game in clam-shell package, then send it all to the address on the form via a shipper that provides a tracking number (Activision recommends UPS 3 day ground shipping). You'll then receive $132, which should cover both the cost of the game and the shipping charges.
If however you decide you enjoy your game and would rather receive a replacement disc, go here.

Got this from 1up.com

 

What's happening with it that would make all this necessary?

N/M, I found out. Some audio glitch or something.

 

Mono FTL

 

I knew I didn't buy it for a reason...

 

I remember hearing a while back that you had to ship back the game first to get the replacement disc, is that the case or do they have an advanced replacement option?

 

i think i'll do the exchange...this'll give me time to play my other games that i need to play.

 

It's stuff like this that makes me glad I'm boycotting Activision.
