Quick Answer
Before major missions, do not prepare only the active character. GTA V often switches protagonists, so Michael, Franklin, and Trevor all need armor, ammo, core weapons, and appropriate vehicles before heists and finales.
Recommended Route
| Stage | What To Do | Watch Out |
|---|---|---|
| Armor | Buy best available armor on all protagonists | Not only one character |
| Ammo | Restock rifle, shotgun, sniper, and explosives by mission | Do not ignore backups |
| Vehicle | Prepare mission or getaway vehicle early | Searching mid-mission wastes time |
| Save | Manual save before major jobs | Recover from bad prep |
Key Checks
- Switch through all protagonists before major missions.
- This matters most before finales and heists.
- Prep failures are easier to prevent than skill failures.
