Enter the Gungeon – How to 100% Complete The Ammonomicon

Yep, you heard that right. I am going to go down every single gun, item, enemy, and boss in the Ammonomicon and what unlock requirements they may or may not have. In Gungeon, the Ammonomicon’s pages are very scattered and don’t list how you unlock items so it becomes very difficult to complete the Ammonomicon without constant wiki checking, so I made this guide in order to help remedy that.

I’ll start with the guns page, and make my way down to the boss page. The items are listed from the Ammonomicon top to bottom and left to right. There are 243 guns and 271 items in Gungeon, so I split pages in order to not hit the text limit on any sections. Still, I recommend using Ctrl + F (or whatever it is in Mac) to find a specific item. Also, I RELENTLESSLY SPOIL EVERYTHING IN GUNGEON WITH THIS GUIDE. If you care at all about keeping some things hidden then do not read the whole guide top-to-bottom.

This 1000 is a cumulative total that can be added towards over many runs. After buying the key once, it will appear every run after then for 115 casings and cannot be discounted in anyway. In chamber 3. there will be a room with rats in. Walk around the room for a bit to find a trap door buried. To unlock the trap door, walk on it a bunch and then use a key. Inside is a minecart rail and at the end you will need to use 2 blanks in order to reveal a wall and then a 2nd wall further in. Use the Gnawed key at the grate to go to the Resourceful Rat’s Lair. Inside here, after dropping down once more, use the cheese arrows at the end of each Infuriating Note (located in the Ammonomicon) to find your way around. FINALLY, at the end you will be able to fight the Resourceful Rat as the only boss of this secret chamber.
