How do you enter the building in Istanbul with the bull skull above it?

[Regulator]

I have xbox live and i saw that cKy517 went into a building, in istanbul, that i tried to go into but when i walked up to it i heard a sound that the door was locked. After he left the building he went onto the highway and hit on coming cars and sent them flying without his car stopping. Did going into the building activate a cheat so that when he ran into the cars he wouldn't stop? And how did he get into the building without it being locked?

thanks

Ohhh, you can only go in there when you kill all the Timmys in Istambul and that unlocks the armory (the building your talking about) witch when you walk in unlocks the infinit mass mode witch alows you to hit a car without losing your current speed. :cool:
