well, yeah, in a way. you have to get an energy sword and a rocket launcher, and empty the rocket launcher's ammo. This is a useful glitch, and you have to try it a few times. Stand away from a partner (in multiplayer, and it has ro be an enemy), and aim your (empty) rocket launcher at him. Once the reticle turns red, you have to rapidly keep switching weapons, and tapping Y, B, and fire. This will zip you to them, but you might have to try a lot. to get on top of zanzibar, you have to stand, with your partner, near the fan, and aim up as far as you can while keeping the reticle red. Once airborne, you have to direct yourself slightly so you don't under or overshoot the fan. There, it's that simple!
