The Book Closed achievement in Deadly Days: Roadtrip asks you to finish the encyclopedia, and I want to walk you through exactly what that actually means so you’re not chipping away at it blindly. This is for anyone who’s stared at that completion bar and wondered what’s still missing or how deep the rabbit hole goes.
Here’s the thing that caught my attention: “complete the encyclopedia” sounds simple until you realize it’s not just about finding every item once. There’s a hidden layer of rarities that a lot of people miss on their first pass. I’m writing this up so you know that going in rather than discovering it the hard way after hours of grinding.
Spoiler warning: This guide references and shows the full completed encyclopedia, including item and enemy entries you’d normally unlock as you play. If you’d rather discover everything yourself, turn back now.
What the Book Closed Achievement Requires
The requirement breaks down into two parts, and both of them matter equally. You need to unlock all rarities of every item, and on top of that you need to discover all items and all enemies. That rarity condition is the one that trips people up — having an item in your book isn’t enough if you haven’t logged each version of it.
Think of the encyclopedia as needing true, full coverage rather than a luck-based partial fill. Before you start chasing specific gaps, confirm whether the missing entry is an item you simply haven’t seen, a rarity you haven’t rolled yet, or an enemy you’ve never fought — because each one is solved a different way.
The Full Completed Encyclopedia
Not every item just shows up through normal play, and that’s where a lot of the completion time goes. For some items you need to unlock characters, buy them from the shady merchant, or craft them yourself. Miss any one of those routes and you’ll have a stubborn blank staring back at you with no obvious explanation.
That’s the part I’d tell any friend to plan for first. If you’re only picking up what drops naturally, you’ll eventually hit a wall where a handful of entries just won’t fill no matter how much you play. Some of those gaps only close once you’ve unlocked the right character, made the right purchase from the shady merchant, or crafted the item you’re missing.
The screenshots above show the encyclopedia filled out completely, entry by entry. Use them as your checklist — scan down the list against your own and every uncovered item, rarity, and enemy will stand out immediately. That’s the fastest way to see what you still owe.
The End
Once every item, every rarity, and every enemy sits in the book, the achievement unlocks and you can finally close it for good. The trick is patience with the routes that aren’t automatic — characters, the shady merchant, and crafting — because that’s where most of the last few blanks hide.
