How to unlock the Shopping Maniac achievement in Neon Abyss - Definitive Guide

You can exploit the turorial's invincibility against the boss on a new save slot to grind flying enemies for coins. I found that shooting the flying creatures the boss spawns and then running over the worms would give you 1 coin on average, but if you jump and melee the flying creatures you often get 5-10 coins.

It took me 20-30 minutes to grind about 650 coins. Don't get impatient and go with less as I had two runs where I was 15 coins short on the last room with no way to get more and had to delete the save and try again. When you have 650 or so coins, kill the boss. Hopefully he'll drop an item that gives you an extra heart or shield because otherwise you only have 1/2 of a heart when you start the next level. Just be very careful until you can get enough hearts or shields.

Make sure to always have at least 3 crystals so you can open the store door without having to shoot it and pay with half a heart. Always go back and max out your crystals/hearts/shields after beating the next boss before progressing. You'll get this achievement on the final level of the first run.

Yes, there's a long setup to grind out those coins, but at least you aren't at the mercy of the RNG to get a lottery ticket or good coin drops/items on a tougher run. You can combine this with the other grindy achievement for running over 999 worms too.

Side note. Don’t buy the lipstick. I had 3 shops bought out, and this item causes the shops to restock.

For what it's worth, the lottery ticket can potentially be found in a shop. Found one today for 70 coins.

My first few times trying this I would accidentally damage the boss too much and it got stressful to reach 650 coins. But if you have the first special gun (Terry), just stand in place and aim down and you can kill the flying enemies without ever touching George. The flying guys run into the splash damage of Terry and drop worms.

*WARNING*

Before traversing too far throughout the upgrade tree I would advise trying to get this.
There are enough upgrades to make the Shop have 6 or 7 items in it rather than the 3 or 4 it starts with.
This will become EXTREMELY difficult the more upgrades you buy through.
I did about 100 or so runs trying to get this before going too far through the tree in order to get this out of the way.

I was lucky with this one. I found a gold door which needs a key to open. Inside the temple is a random item. I found a lottery ticket which gave me over 700 coins. After that, advance through the 4 levels and find a shop in each and buy everything in each and the achievement pops the moment you clear out the 4th shop.

I also got it after finding a Lottery Ticket item. You need approx 660 coins to do it.

As the description says, in a single run you need to buy every single item from four different shops (one per floor). This can be extremely difficult (mainly luck dependent) to do naturally. Thankfully, there is an exploit to take advantage of to basically guarantee this achievement.

What you'll want to do is start a new save file. From the main menu, select Save Slot and choose an empty one. This will throw you into the tutorial (remap the controls if need be). Proceed through the tutorial to the boss fight against George, God of Pills. What's important to realize is that during the tutorial, you can't die. You can get hurt down to half a heart, but then you're invincible. By now you've likely noticed that George continually spawns 3-4 flying enemies, and when you kill them, they tend to drop worms. Stepping on those worms releases at least one coin, but sometimes multiple. Since you can't die, what you're going to do is avoid shooting/killing George, and instead just keep killing the enemies he spawns, stepping on the worms they drop so you get coins. In a shop, there is always a weapon for 40 coins, an item for 70 coins, and two items for 30 coins each, meaning you need 170 coins per shop, so 680 coins total across all four shops. You can therefore farm enemies against George until you grind out at least 680 coins. It may sound tedious, but it actually doesn't take that long at all (20 minutes, maximum). To be safe, I recommend grinding out more. I went all the way up to 999 to be safe (that's the max you can have). Once you're done grinding coins, finish off George.

Here's the only tricky part: after beating George, you'll presumably still have only that half of a heart left at the start of the next level. Worse, and what's important to be aware of, is that even though the game says you've now on Floor 2 after beating George, the game considers it the first floor if you try to use the Save Reload Exploit. This basically means that, after grinding out that money, you now need to get through the next floor without accidentally dying. Assuming you're playing on Easy, this shouldn't prove too challenging. Just play it safe in combat rooms, and try to get to the first shop ASAP so you can buy either the heart or shield for sale there, plus the item and weapon to help survive.

Once you get through that first real (non-tutorial) floor (making sure to buy everything at that shop), the rest of the floors shouldn't be an issue. You can use the Save Reload Exploit whenever if need be, and since you have so much money, you shouldn't have any issues surviving and having good weapons and items. You'll obviously need to progress to the shop on the fifth floor, buying everything on the way, but as soon as you buy everything from the shop on the fifth floor, this achievement will unlock.
