GTA 4 100% Completion Rewards

Unlocked by	Finishing everything on the 100% checklist
Notice	“100% Game Completion.” in the top left of the screen
Achievement	Key To The City, worth 100 Gamerscore or a gold trophy
Reward	Unlimited ammo purchases for every weapon

When your counter reaches 100%, the game shows “100% Game Completion.” in the top left and the Key To The City achievement pops up. That is the whole announcement. There is no cutscene and no new area, so it is easy to miss if you are mid-fight. It usually lands on whichever item you finish last.

The top left reads 100% Game Completion while the Key To The City achievement appears above Niko on a plaza.

Unlimited ammo

The practical prize is that you can buy as much ammunition as you like for any weapon. The price stays the same as before, but the usual carry limit is gone. Weapons themselves come from the same places as always, see Weapons. Stock up in gun shops and from Little Jacob once his ability is open.

Niko holds a pistol at a gun shop table as the screen says a Micro-SMG was purchased.

Help text says Little Jacob sells guns and equipment at discounted prices as an achievement pops up.

A helipad with an Annihilator and the line about unlimited ammo as the reward for 100% completion.

There is a catch. When you load a save that already has 100%, any ammo above the normal limit is lost. So buy your big stacks after loading, not before saving and quitting.

Annihilator helicopter

Killing all 200 Flying Rats is a separate prize. A helipad on a Liberty City rooftop gets an Annihilator, an armed helicopter, waiting for you, and the game tells you so with an on-screen line. Walk over and take it. See Flying Rats for the full hunt.

Niko crouches on a rooftop walkway as the line names the Annihilator as the reward for 200 flying rats.

Exotic exports

Each export car goes to a lockup where you can keep it. The bike delivery ends with a call from Brucie that tells you it is parked there. After all 10, you also get the achievement. The lockup cars are yours to drive whenever you want, so it is the best way to get rare rides. More in Vehicles.

A dark red car rolls into the open bay of Brucie's lockup with a taxi behind it.

A red SUV drives into the lockup bay with the order to park the car in Brucie's lockup.

Races

A win pays $500, shown in the corner as soon as you cross the line. It is small money, but it adds up if you repeat circuits for the achievement. See Money.
