GTA 3 100% Completion Guide: Checklist and Mission Order

100% in GTA III is not just finishing the story — it means closing 154 required objectives, each worth about 0.65%. All of it works in the browser version: same saves, same controls, no differences from the PC release.

Rule one: side content before the story

The further you go, the more hostile the gangs become and the heavier their weapons. Rampages, vehicle missions and Vigilante become much harder after that.

  1. Portland. Clear every side activity on the island first — rampages, unique jumps, vehicle missions, payphones, Paramedic, Firefighter, Taxi, Vigilante. Then continue the story until you leave for Staunton.
  2. Staunton. Same pattern: finish the island before “Kingdom Come”.
  3. Shoreside Vale. Finish before the final mission “The Exchange”, after which the gangs are at their most aggressive.

Missions you can lose forever

This is the usual reason for being stuck at 99%. Several missions are disabled if you complete others first:

Vehicle sub-missions

Collectibles: 100 packages, 20 rampages, 20 jumps

Import/Export

Three vehicle lists: the Portland garage, the Portland crane and the Shoreside Vale garage. Deliver cars intact and keep the list handy — rare vehicles are easier to find in specific districts at specific times.

Common mistakes

  1. Finishing the story first, then trying rampages against gangs with shotguns.
  2. Skipping a Kenji, Luigi or Joey mission and losing it permanently.
  3. Collecting packages without notes and losing track of the missing ones.
  4. Attempting unique jumps in a slow car and missing the landing zone.
  5. Not saving before long side activities — the browser build can crash too.

FAQ

How long does 100% take in GTA III?
About 20–30 hours for an experienced player. Most of the time goes into packages, taxi fares and import/export, not the story.
Can I finish 100% after the last mission?
Technically yes, but rampages and vehicle missions become much harder against armed gangs. Clear each island before moving on.
Do I need cheats?
No. They do not block progress in the original game, but they undermine the run and are unnecessary in the browser version.
Does progress save in the browser?
Yes, locally and in the cloud after signing in — important for a long 100% run.
