Grand Theft Auto 4 (GTA:IV)
 

Last night in free mode a friend saw this while driving around the airport.

Yes you can see people hanging of a train (you cannot drive trains even in game mode) that is driving around the airport, plus the trains arn't available in on-line mode.

So much for stopping modded boxes on there.

That's on the normal version of the game? I've only ever seen modding on The Ballad of Gay Tony.
