Quick Answer

For a first playthrough, follow the story until all three protagonists are fully established, then weave heist prep, key side content, and money planning into the main route. Do not chase 100% from the opening hours; many collectibles and activities are faster after your vehicles, weapons, flight control, and cash improve.

Mission Prep Checklist

  • Check whether a heist setup or character-specific mission is active.
  • Buy armor, ammo, and a reliable weapon before major jobs.
  • Preserve assassination missions that can amplify stock market gains later.
  • Confirm getaway vehicle placement before heist finales.
  • If you want more story context, clean major strangers and character interactions before the ending.

Before The Ending

Make a manual save before the final branch. After the story, focus on 100%, gold medals, stunt jumps, letter scraps, and spaceship parts as a separate cleanup route instead of interrupting the first run.
