Enter the Gungeon - Ammonomicon Gun + Bosses + Enemy And Unlock Requirements

Enter the Gungeon – Filling Out the Ammonomicon in Enter the Gungeon

Yep, you read 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.

This guide also works as a completionist guide as well, however, some things needed for completion such as unlocking characters and achievements I will not be covering as this guide is focused wholly on the Ammonomicon. I’m not ashamed to admit that this guide is borrowing some information from the wiki [enterthegungeon.gamepedia.com] as I haven’t completed Gungeon myself. Feel free to visit the wiki if you need more in-depth answers than what I provide.

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.

Where to Find: After finding Sir Manuel’s remains in the tutorial and speaking to him, he will tell you to go find and kill the traitor. After this, Blockner can be found in Chamber 3.

The Resourceful Rat

Where to Find: After assembling the Bullet That Can Kill The Past, the Gnawed Key will appear in the shop in place of the Prime Primer for 999 casings. 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.

Conclusion

Whew! My hand hurts now. Anyway, that is the complete catalog of every gun, item, enemy, and boss in Enter the Gungeon. Let me know if I missed anything or if anything is incorrect. Also, let me know if you want this guide expanded to including synergies or something. I know this guide is purely Ammonomicon stuff, but I don’t mind making additions. I hope you enjoyed this guide and find it useful on the path towards being a true Gungeoneer.
