Note - This game is by a user on the forums named NocturnalStudio.
I am working so he can come and post himself here but I wanted to get this info out so other developers can give him a hand testing his latest game.
The game has a very cool heavy metal soundtrack and they went thru and got the bands permission to include the music.
So there are not any licensing/rights problems with this.
We just submitted our first MMF2 title for XBLIG review- we hope you'll check it out and help us get our game through peer review!
Enjoy & Thanks!
