Cipher Coin

Cipher Coins are round, green coins and the main extra collectible found throughout Plague of Shadows. Similar to the other Collectibles, once a coin is collected, a transparent gray version of it will mark where it once was. Collecting a grayed out coin will not increase the total coin amount. There are in total 420 Cipher Coins throughout the campaign.

A Cipher Coin can also be found embedded in a wall in each stage of the Order of No Quarter members with the exception of Pridemoor Keep. They indicate hidden areas where Plague Knight can obtain Relics (or trade with Chester in the Iron Whale). By pressing [SELECT] while hovering on a stage in the map, the Items Totals Menu is accessed revealing not only the number of Cipher Coins collected but also which Scrap Sheets are missing in said stage. Checking the Gear tab while inside a stage will yield similar results.


The numbers of Cipher Coins in each stage vary by type:

Cipher Coins can be spent with Mona or Percy in the Potionarium on research. Each research unlocks more options for Plague Knight's bombs to be bought in gold. The Catapult in the Armor Outpost also requires Cipher Coins for Percy to fix it.

  • 40 - Research 1. Unlocks Float Casing, Component Powder, Quick Fuse, Sentry Fuse, and the Bullet Burst
  • 60 - Research 2. Unlocks Orbit Casing, Cluster Powder, Remote Fuse, and the Frost Burst
  • 80 - Research 3. Unlocks Drop Casing, Whirl Casing, Sparkler Powder, Impact Fuse, and the Spin Burst
  • 50 - Fixes the Armor Outpost Catapult

If all 420 Cipher Coins are collected and taken to Percy at the Potionarium, Plague Knight can obtain the Pandemonium Chalice. Obtaining the Pandemonium Chalice will also fix the catapult if this has not already been done. The Pandemonium Chalice can be shown to the Troupple King to receive the Pandemonium Cloak.


  • As Plague of Shadows is the only campaign that includes multiple types of collectible items, Cipher Coins are the only collectibles that are never exchanged for 500 gold each, as that role is already filled by the Scrap Sheets.
