How This Guide Is Structured

Every chapter mirrors the in-game flow so you always know what is optional versus mandatory:

  • Quest Tracker widgets call out when a quest starts, progresses, or completes.
  • Collectible Alerts flag every costume piece, Creepy Treat Card, and key upgrade.
  • Trophy Callouts show when to trigger missable achievements without backtracking.
  • Boss Sections break down recommended parties, elemental matchups, and special mechanics.

Feel free to follow sequentially or cherry-pick what you need—the routing assumes you want a single, efficient 100% playthrough.

Suggested Completion Route

  1. Act 1 – Auburn Pines & The Bayou
    Unlock Clown and Pterodactyl early, trigger Hardcorn Mode immediately, and farm candy before moving to the Witch's Bog.
  2. Act 2 – Academy to New Repugia
    Finish the speakeasy delivery chain, complete Wizard/Pharaoh sets, and keep pace with Corvus' counter lessons.
  3. Act 3 – Dental Compound & Time Travel Loop
    Sweep the compound for Ghost, Hot Dog, and Solar System costumes while juggling past/future errands and prepping for the Orel White showdown.

Key Planning Tips

  • Hardcorn Mode Friendly: Our step lists mark the single Corvus tutorial fight where Candy Corn can sit out—every other encounter includes reminders to keep it equipped.
  • Costume Upgrade Priority: Focus on Superhero, Clown, and whichever third-slot you prefer for elemental coverage; Act 2 shops are tuned around this.
  • Card Usage: Whenever a card is earned, the walkthrough tells you when to play it so you never miss Creepy Card Shark.
  • Grinding Spots: The Witch's Bog and Dental Compound patrol loops are highlighted if you need extra XP or candy before boss walls.

Trophy Roadmap

Want trophies in order? Start with the dedicated Trophy Guide for rarity tiers, then follow the act pages for exact trigger points.

Recommended Prep Before You Start

  • Check Shady's Shop after every quest chain; inventory updates frequently and is noted in the steps.
  • Talk to Every NPC in new hubs to unlock side quests early—you'll loop back for delivery turn-ins, but you can queue them right away.
  • Track Hide & Seek / Trespassers as you go; each act page lists the exact order so you never lose count.

Suit up, grab your Creepy Treat cards, and let's make sure Halloween stays saved—again. Happy trick-or-treating!
