Full Walkthrough: http://www.gamefront.com/bulletstorm-walkthrough/
Use your leash to pull down the roof on the second Skull to get a "Ding Dong" kill. Head outside and kill the group that will be waiting for you. Use your sniper to take out the turret gunner in the distance, then go pick up his gun.
Use the gunner to wipe out the huge group of Skulls standing up in the subway line. Once the railcar kills the last of them, head down the subway tunnel.
After you fall through the shaft door, head down the path. There will be a Dropkit up ahead----use it if you need to. Climb over the two fallen columns and wipe out the next wave of Skulls in the large room to the left.
Crouch to get through the tiny crawl space on the other side and follow it around. Kick through the barrier and kill yet another wave of Skulls as you make your way through the room.
Once outside----you guessed it, another group of Skulls. Have fun kicking them off the huge drop-offs. With the area cleared, head through the hole in the next building.
If you slide straight under the narrow crawl space, you'll find some spare ammo. Walk back up the ramp and when you see Trishka and Ishi, turn right into the checkered -walled room.
Use the Dropkit, then sprint up the glass slope. Climb over the barrier and make a quick right through the next hole in the wall. Turn left past the falling debris. When you reach the bathroom, take out the two Skulls and continue on.
Kill the next groups of Skulls in the open area. Head up the embankment to the left and kill the attacking group of Skulls. Head into the next structure. Kick in the broken piece of wall to the left, then another one in the next hallway.
After you turn down the slope (and Gray yells, "This shit is happening!"), you'll have thirty seconds to get out of the building before it collapses. Sprint down the slope, then make a right, another quick right and another right.
Kick the Skull out of the way, turn left and sprint for the railcar. Hit X on the control panel to get it moving. Hit RT when Ishi tells you to shoot the tanks.
