3. Flying Cars
No, you're not looking at a scene from Back to the Future. This is a screenshot from GTA IV of Niko Bellic taking a car for a quick... Flight. The flying car cheat has been prevelent in the Grand Theft Auto cannon ever since the PlayStation 2 days, and has provided gamers with a variety of uses - from soaring over broken bridges to access islands before they had been unlocked in the storyline, through to just having some crazy old fun. The flying car cheat also came useful in street race missions, where you could enable the cheat, watch the opposition fly off into the ocean, disable it and complete the race with ease. Considering this code provides the player so many advantages, it would be almost criminal not to include it in GTA V.
