This is it. The big one. The one that will seperate the boys from the men (and women). You will have to play through the Endless Setlist 2 without pausing or failing a song. Firstly, people have come up with schemes of disconnecting their controller, hitting the guide button etc. Take warning that none of those work, Harmonix obviously knew what people were going to do. This does not have to be done on expert, so do it on medium so that pretty much gets rid of the no failing part. You can fail and be saved by someone, as long as you don't fail the whole song and have to restart. Make sure you have a wired controller, so your batteries don't die on you, also make sure no one unplugs the wire. When deploying overdrive, guitarists, tilt your guitar, don't press the back button, to make sure you don't accidentally press the Start or Guide button. One way you can do this is swap in and out with a friend, each doing a couple of songs. You will probably have to return the favour too. Make sure you have done everything you need to do before attempting this. I think the best way to do this is to wake up early on the weekend, and play that whole day. This can obviously be done with a band, but at least if you do it by yourself, there is less risk and nobody to blame.
