100%: Grand Theft Auto III

Full completion requires planning because changing gang relations can make later activities considerably harder.

Checklist

Complete required and available side missions before their points of no return.

Use a numbered list; every ten packages add a reward to the safehouses.

The game must confirm success. A triggered but failed Rampage moves to another location.

Vigilante, Paramedic, Firefighter and Taxi are best completed during the safer early stages.

Vehicle lists and remote-control challenges are among the easiest requirements to overlook.

Compare the individual counters, not only the overall percentage.

If an employer disappeared after progress in another strand, an older save may be necessary.

Do not change main.scm or major gameplay mods during a 100% run.
