How to unlock the Blitzkrieg achievement in Guitar Hero: Metallica - Definitive Guide
UNOBTAINABLE, DUE TO SERVER CLOSURE
With all 4 instruments connected select "online" from the main menu and either create a band vs band match or search for one. A band vs band match is when you play with your band against another band, on any song and the band with the higher song at the end of the song wins. You will have to win to obtain the trophy.
NOTE: Lately there are hardly any people playing online so it's going to be very difficult to find anybody playing online. I suggest using the Boosting thread found here: Trophy Boosting Thread
