:P Not much of a secret, as juggleknot pretty much described it. With the bandana, you can toss an unlimited amount of stun gernades. All you have to do is, once you're on the staircase, just press left on your controller. This will keep you running up the stairs. Toss a stun gernade everytime the flash just starts to dissipate, this way you find a nice compromise between being able to see and keep stunning the guards. Have fun! And don't get elbowed on the way up, eh.:thumbsup:
