GTA IV 100% Completion: The Full Checklist and Reward
GTA 4 100 percent completion explained: every story mission, the 200 flying rats, 50 stunt jumps, friend tasks, and the exact reward you unlock.
Reaching GTA 4 100 percent completion means clearing the full story plus a long list of side tasks scattered across Liberty City, from killing 200 pigeons to winning games of pool, darts, and bowling. The good news is that the checklist is fixed and well documented, so nothing is left to chance. This guide walks through every requirement for the base game (not the two episodes) and confirms the exact reward.
How GTA 4 100 percent completion is weighted
The completion meter is split across story, friends, side jobs, police missions, activities, and collectibles. The biggest chunk by far is the campaign: there are 88 required story missions, worth roughly 60% of the total. Everything else fills the remaining 40%. You can track your running percentage at any time from the Stats menu under "Game Progress," which is the cleanest way to spot what you still owe.
A few things that look like requirements are not. The episodes (The Lost and Damned, The Ballad of Gay Tony) have their own separate completion meters and do not count toward the base game's 100%. The mission "One Last Thing" awards no percentage either, so don't panic if your meter doesn't tick after it.
Finish the story and the required random characters
Play the campaign from "The Cousins Bellic" through to either ending: "A Revenger's Tragedy" (the Deal path, where Roman dies) or "Out of Commission" (the Revenge path, where Kate dies). Both endings count the same toward completion, so you only need one playthrough. For a refresher on the campaign's high points, see our GTA IV game hub.
You also need the random character encounters. There are 14 random characters in Liberty City, but only 10 count toward completion, and you must finish every available encounter for each of those ten. The four that do not count are the ones you can kill during story missions (Ivan Bytchkov in "Ivan the Not So Terrible," Cherise Glover in "Ruff Rider," and Clarence Little in "Holland Nights") plus Brian Jeremy, so don't worry if those never appear or you take them out. Missing one of the ten required randoms is a common reason a save stalls at 99 point something percent.
Side jobs: drug runs, assassinations, and car theft
Four phone- and text-driven job lines are mandatory:
- Little Jacob's drug deliveries: all 10 runs, triggered by phone once they unlock.
- The Fixer's assassinations: all 9 contracts, picked up from a payphone in Alderney.
- Brucie's Exotic Exports: all 10 vehicles, sent to you by email and marked on the map for stealing.
- Stevie's Car Thefts: all 30 vehicles. Stevie texts you a new car description (with a photo) one at a time, so this line is paced by play and is best started early.
There is also Brucie's street racing: win all 9 races to bank that slice of the meter.
Police computer: Most Wanted and Vigilante
Hop into any police car, access the in-car computer, and you'll find two job lines that both count:
- Most Wanted: 30 criminals total, 10 on each of the three island groupings (Algonquin, the Broker/Dukes/Bohan cluster, and Alderney). The percentage only registers once all 30 are dead. Clearing them also unlocks the Manhunt achievement.
- Vigilante: complete 20 vigilante crimes via the "View Current Crimes" option on the same computer.
Activities: pool, darts, bowling, and QUB3D
Four pub-and-arcade activities are on the checklist, and each only needs to be cleared once:
- Win a full game of pool.
- Win a game of darts.
- Win a full game of bowling (a complete game, not a single frame).
- Beat the developer's high score in the QUB3D arcade game, which sits at around 10,950 points. QUB3D cabinets are at the Homebrew Cafe and a few nightspots like the Triangle Club.
Friends: activities and special abilities
The friendship layer has two parts, and both matter. First, take each completion-relevant friend (Little Jacob, Brucie, Packie McReary, plus Dwayne's-circle contacts where they apply) to every available activity at least once: bowling, darts, pool, drinking, eating, the strip club, the cabaret show, and so on.
Second, raise their "like" stat high enough to unlock their special abilities, which is its own completion requirement:
- Brucie: a helicopter pickup for fast travel.
- Little Jacob: discounted guns delivered to your location.
- Packie McReary: a car bomb you can plant and detonate by phone.
Keep relationships warm by answering calls, accepting hangouts, and matching each friend's preferred activity. Let a like stat slide and the ability locks again, so finish these before you taper off the friend mechanic.
Collectibles: 200 flying rats and 50 stunt jumps
The two big map-wide collectible hunts are the ones most players save for last:
- Flying rats (pigeons): kill all 200. They roost on rooftops, under bridges, on docks, and along the waterfront, glowing faintly and cooing so you can hear them nearby. A printed or on-screen map is close to essential here. Finishing all 200 also spawns an Annihilator attack helicopter on top of the MeTV building in Algonquin as a bonus.
- Unique stunt jumps: clear all 50 ramps. You need to land the jump cleanly for it to register, so a fast bike like the NRG 900 makes the harder gaps far easier. Our GTA IV cheats page lists vehicle and weapon spawns that help with both hunts.
The reward for hitting 100%
Once the meter hits the top, you get a "100% Game Completion." message in the corner of the screen, and the practical payoff is the ability to buy unlimited ammunition for every weapon from gun shops and Little Jacob (it still costs the same per purchase, you just never run dry). On consoles, the milestone also pops the Key to the City achievement/trophy. Pair it with the no-deaths and no-busts requirement that some completionist runs chase, and you've got the cleanest possible Liberty City save.
