This FAQ is a collection of all the hidden details, secrets, glitches, tricks, and any related matter from GTA IV.
I've been playing GTA for a while now, and have also run a site dedicated to the GTA series for a few years. I enjoy just playing around in GTA, looking for glitches and secrets, more than I play missions.
Many of you may remember me from the GTA San Andreas Secrets FAQ - I'm the same author, and hope that this one is just as successful.
