I’m not going to hide anything here—this is a full, straight-up guide with everything laid out. If you don’t want spoilers, this is your warning. I’m not going into story details, but all items, upgrades, quests, and locations are mentioned openly.
One important thing before you start: make sure you hit 100% completion before triggering the final boss. If you don’t, you’ll have to replay that ending sequence again to get the achievement. You can always check your percentage from the main menu.
Also worth mentioning—nothing here is missable. You can go back and clean things up if needed.

That’s everything. If something feels confusing while playing, it usually just means you’re missing a quest trigger or upgrade—so double-check your progression and areas.
