How to unlock the Resourceful achievement in Enter The Gungeon - Definitive Guide
To unlock this achievement, you have to beat the first 2 phases of the Resourceful Rat boss fight.
The first part of the achievement involves actually getting to the boss. Your first goal should be getting the 6 Infuriating Notes in order to navigate the new bonus floor where the Rat is the boss. They are found randomly in chests, except for the 6th, which can only be dropped by mimics once you have the first 5. You only need to find each note once; they'll be in the Ammonomicon to look up later. On each note, there is a piece of cheese pointing in a direction, and they are unique to each player.
You'll also need to unlock the Gnawed Key, which you can work towards while farming the notes. The Gnawed Key is available for purchase in the shop on the Second Level - the Gungeon Proper. It initially costs 1000 shells, but you don't have to pay it all at once. Just keep putting money towards it when you can. Once you unlock it, it will always be available for 115 shells in this store.
Note: You can also steal the key. If you steal the key before the finish the money grind, it will return next run at whatever price it was before you stole it. Given its price, it can still be useful to steal it even once you've finished the grind.
Now to get to the Resourceful Rat's Lair. On the third floor of the Gungeon - the Black Powder Mine - there will be a room with a few rats running around. In this room, there will be a trap door that starts the Route to the Resourceful Rat's Lair. You can reveal the trapdoor with explosions, liquids, or just running over it. Running on it creates a larger than normal dust cloud. If running, you'll need to continue walking over it for a few seconds to make it interactable. You'll then need a regular key to open the trapdoor.
Once you've opened the trapdoor, you'll be in a long room with just a minecart track. When you ride the track to the end, you'll need to break the secret door to the North. To do this you need either:
- A Blank
- Armor (jump into the pit and it triggers a blank-like effect)
- Lil' Bomber or the Bomb Active Item
Once you've broken this wall, you'll be in a short hallway. There is another wall at the end of the hall you must break. Jumping into the pit won't work here, but if you have a way to injure yourself near the wall, you can still use the armor trick. Once through this wall, there's a trapdoor to open with the Gnawed Key.
You are now in the Resourceful Rat's Lair. Go to the next room and there will be a pit to jump into. Once you've jumped into the pit, you'll have to check the Infuriating Notes in the Ammonomicon to see which direction you need to go. Follow the directions the cheese points to. For example, my notes were - Down, Right, Left, Down, Left, Right. Once you've followed your directions, you'll reach a room with a few pickups, and a door to the North will lead to the boss battle.
The Resourceful Rat is a 3-phase boss battle, but you only need to finish the first 2 phases. From here, it's just up to you. Here's a guide to all his attacks. Here's also a sample of me fighting him. I lose on Phase 3, but as I stated, you don't need to win here.
In order to have the best chance of beating him, I'd recommend you completely clear out every floor before his lair to make sure you have a good stash of items. This also helps you save money for the Key (if you don't steal it). This would include:
- The First Floor - Keep of the Lead Lord
- The First Bonus Floor - the Oubliette (Instructions on how to reach. Make sure you pick up the Old Crest to reach the Abbey of the True Gun
- The Second Floor - Gungeon Proper
- The Second Bonus Floor - Abbey of the True Gun (Must carry the Old Crest to an Alter on the Gungeon Proper to reach. Any damage will cause you to drop the Old Crest)
- The Third Floor - Black Powder Mine

Great guide except that the second hidden door cant be opened by jumping into the pit with armor for some reason.

It's likely considered a separate room; blank effects only cover one room. If it wasn't like this, you'd just be able to open both walls with 1 blank.

To get to the rat you must fulfill a number of conditions:
1) Collect five notes with a piece of cheese (they will sometimes fall from chests instead of things, the thing is cumulative, you will collect it for a certain number of times), as soon as you collect all five, you can see them at the very bottom of the list of items open in the directory, on each note there will be a drawing a piece of cheese directed in a certain direction, they show the pattern of movement in the rat's lair
2) You need to buy the “Gnawed Key from the Trader”, the key will always be sold on the 2nd floor of the gun and at first it will cost 999, but its price tag will become 115 forever, after you pay all 999 (bringing down the price is a cumulative activity, just save money every time to the merchant and pour it on the key)
3) After purchasing the key, you need to go to the 3rd floor of the gun and there find the passage to the rat’s lair, it’s easy to find, in the room where the hatch will be running 3-4 rats, the hatch is covered with dust, the outlines will be visible, you just need to run along it and it will appear on map and you can jump into it, I strongly recommend that before jumping into the hatch you finish the entire floor and kill the boss, since you will need all the equipment and loot, you also need to save 2 dummies!!!
4) So we have 5 notes, a gnawed key and we found a hatch; to open the hatch you need one regular key, so we need to save it.
We open the hatch and jump into it, we get into a junction with the trolley, we sit down and drive to the end of the tracks, we get off the trolley and use the dummy, a passage will open, we go into it and go all the way, we use the dummy again, a passage to the hatch opens, we approach the hatch and open it with the gnawed key, jump and end up in the rat’s lair, approach a round cliff and jump into it
5) The most difficult part begins, you need to clear 5 rooms from the 5 notes that you have as quickly as possible, the whole level is a series of labyrinths and if you spend a long time fiddling with clearing the boss you won’t get to the boss (the passage will close), so you need exactly those rooms that indicated in the note, we focus on the arrows made of cheese (for example, I had right, right, left, down, left, left), if you did everything correctly, you will get into the room in front of the boss, there will be a heart and cartridges.
The boss is difficult with two stages
