This guide will walk you through the Bulletstorm ‘Itchin’ to Crumble’ mission. Let’s get started!

Upon rescuing poor old Ishi from the Maneater, head through the underground tunnel and get back outside. Walk to the edge and press the action button to grab unto the bars above. Follow Trishka and make your way across the platform / ledge. Upon crossing the top of the waterfall, use the nearby Dropkit and proceed. Head into the building and continue along the path until you reach a hole in the wall. Hold LT when prompted to. Follow Trishka around the building and double tap the A button to slide down the hill. Wait for Ishi to kick in the wall behind you to proceed. When you see the holographic clock, prepare to be ambushed by a few Skulls. Take them all out. Head outside and eliminate the group of Skulls waiting for you there. There should be a turret gunner somewhere in the area trying to shoot you down from afar, take out your sniper rifle and make a well placed head shot to take him out. Go to where he is and take his gun.

Use the gunner to eliminate the remaining enemies near the subway line. When the railcar arrives and destroys the rest, head down the subway tunnel to continue. Head down the path after falling through the shaft and there will be a Dropkit waiting for you. Use it if you must and then proceed.

Two fallen columns will be blocking your path. Climb over them and take out the few Skulls on the other side of the area. Crouch to get through the tiny hole in the wall and make it to the other side. Follow the wall around and kick in the barrier blocking your way. Take out the handful of Skulls in the nearby room to the left. Upon exiting the premises another group of hostiles will attempt to kill you. Take them all out and proceed to the hole in the wall in the next building.

Slide straight under the tiny crawl space and pick up the spare ammo. Take the ramp back up and follow Trishka. Ishi will guide you into a checkered themed room. Use the Dropkit inside the room and make the most out of it, you’re gonna need it before the level ends. Turn left pass the fallen debris on the area and head to the bathroom. There should be a few Skulls trying to take a piss, take them out and continue.

Another group of Skulls will be waiting for you in the next area, do what you normally do with them to continue. Head up the structure to your left and kill off another group of Skulls. Head into the next structure and take out the hostiles there as well. Kick in weak part of the wall to break it and enter. There should be another weak wall in the hallway, destroy it as well and proceed.

After you turn down the slope and Gray yells at you all, get out of the building as fast as possible. You have about thirty seconds to do so before the entire building collapses and kills you. Sprint down the slope and take a right, then another right, another quick right and another right to exit the building. Kick the Skull blocking your path and make your way towards the railcar. Hit X on the control panel to activate the railcar. Hit RT when Ishi tells you to.
