RewardsEdit
The reward for 100% in GTA IV is the ability to buy an unlimited amount of ammunition, although it still costs the same as before, and the Key To The City Achievement is unlocked. This reward has a bug where, when the player loads a 100% saved game, all the ammo that was over the original limit is gone. Also, after killing 200 Flying Rats an Annihilator sporadically spawns on a helipad in Star Junction.
