Max Payne 2: the Fall of Max Payne Cheats (Xbox)

When Vlad is on the big green platform above you the way to kill 
      him is to shoot the four cable bases, the platform should then 
      fall. Next use the MP5 and zoom in(X button) and shoot out the 
      four yellow bars. The spike will then fall. Vlad will then be 
      visible to be shot.

  

  

In the chapter where Max is suspended in the police station, go to 
      the rec-room. There will be 2 police men on a couch watching tv. 
      Turn off the tv and watch them turn it back on, then turn it off 
      again, repeatedly (cops will not do anything to you).
