I MAED A GAM3 last for 13 minutes and 37 seconds and splits up into 7 sections. With practice you should easily be able to reach the end of the song. Overall, the Power Ups you should be avoiding are the Laser and the Rocket. The Shotgun can be useful, but it's slow fire rate can cause problems. If you see a flamethrower or a Ninja Star shooter and it's safe to go get it, grab it because they are both excellent crowd control guns and will help you extremely when playing this mode. But of course only go for power ups when you know you won't die.
