If you are trying to get all of the achievements, I recommend going into this game knowing everything you can. This game autosaves, and there is no way to reset your progress without creating a new Steam account. There are things you can do in the game that can permanently prolong your progress from beating the game ― let alone getting 100% achievements ― such that it would be faster to create a new account to get 100% achievements.

These two video guides are 3 hours long, but they cover the basis of the game and combat much clearer and more exhaustively than the in-game tutorials and messages.

In fact, the community-maintained wikipedia[letitdie.gamepedia.com] has more correct information about the game than the in-game text and dialogue. Having a deep understanding of the combat and knowing to continuously R&D your gear will propel your progress to get all of the achievements.

I have split the next sections by achievement. The sections closer to the top are the ones you should think about as soon as possible while the sections closer to the bottom are the ones you can prioritize later or will inevitably occur over the course of the game. Minor spoilers are present past the TDM sections.

I will point out various things that have changed between 2021 and the release of this game since other guides and comments on the Internet may refer to outdated information that has been changed since the release of this game.

TDM (Tokyo Death Metro) is what makes the 100% of this game very long. TDM unlocks as soon as you defeat the first boss[letitdie.gamepedia.com] on the third floor.

Flirting Virtuoso
Capture 100 Fighters


Impregnable Fortress
100 successful home defenses


Circle Crusher
Achieve 100% home destruction on other players' bases 100 times


Here are few TDM things that have changed since the launch of the game:

• Capturing a fighter is no longer dependent on level and the difference between the level of the defense fighter and your own fighter. Any fighter of any level can be captured.
  
• Raiding no longer has a KC fee.
  
• Your TDM Fighter Rank can only go up, not down. (This Rank is different from the TDM Rank that corresponds to Bronze/Silver/Gold/Platinum/Diamond.) Unlocking a new grade does not change your Rank, and deleting a fighter no longer lowers your rank. Once you purchase a fighter, your rank will irreversibly change if applicable.

The TDM Fighter Rank Formula is 15*(Highest Fighter Grade Bought - 1) + Current Amount of Fighters of that Grade
Grade 1: 1 - 10
Grade 2: 16 - 25
Grade 3: 31 - 40
Grade 4: 46 - 55
Grade 5: 61 - 70
Grade 6: 76 - 85
Grade 7: 91 - 100
Grade 8: 106 - 115
If you want to replace a fighter of the highest grade bought without raising your rank, you can delete a fighter of that grade and then purchase another one. This will not increment your TDM Fighter Rank.

Flirting Virtuoso is RNG dependent, and Impregnable Fortress depends on others to attack your base and for them to lose. These two achievements need to be kept in mind lest you lose significant real time from achieving 100%. Here's the strategy:

TLDR: Keep your TDM rank low (1-40). Continuously work on your R&D, and participate in every TDM war. You may advance your rank when you have achieved Impregnable Fortress

First, when choosing a team, choose a team that has the fewest amount of players but with a high TDM rank average. For example,

For getting the TDM achievements, the most important thing is to just be in an active team: an active team is any TDM team that gets into a TDM war every 2-3 days. Any active team is a team that has a high TDM Rank average and/or a team will a high sum of win and losses. The more war you are involved in, the more you can raid and defend, and the more you raid and defend, the more progress you make for your TDM achievements. In a TDM war, the smaller team gets an underdog bonus that helps the team get a victory, and winning confers bonuses. Though do beware that small teams can have their active members leave for other teams and become inactive, forcing you to carry the team activity, so it may be safer to also choose a larger active team so as long as they have a decent win ratio.


The main strategy is to keep your TDM Fighter Rank low until you have completed the Impregnable Fortress achievement. When players raid, they get to see the player's rank before they choose who to raid.

Luckily, players cannot see your playtime and R&D progress which allows you to twink[en.wikipedia.org]. Through bloodnium[letitdie.gamepedia.com], you can unlock an extra decal slot for your fighters; being able to apply an extra decal to your fighter can significantly strengthen your fighter. Through R&D, you can increase your weapons and armor above what is normally expected your base to have, and through discount decals[letitdie.gamepedia.com], your fighter can bypass the stat requirement of your gear to wear and use them. This twink strategy is required because players are less likely to attack way above their rank and are more likely to attack a base below their rank ― the lower the rank, the more likely to get raided. But, in order to have a successful defense, your base needs to defeat these raiders who are likely to be overleveled compared to your base, so twinking is almost necessary to get Impregnable Fortress.

Unfortunately, twinking in Let it Die takes a long time. Splattershrooms spawn very rarely on floors below 40, and most of the powerful decals in the game require you to spend 50,000 KC and get lucky in receiving a decal. You will need to reach the shop floor at the 27th floor level with a grade 1, 2, or 3 fighter without having purchased a grade higher; the lower your rank is when you reach floor 27, the better it is for getting the Impregnable Fortress achievement. (At grade 4 and higher, uncapping your fighter requires way a large amount of bloodnium). Once you reach YUKIYOSHI shop floor[letitdie.gamepedia.com], you will continuously use this shop to buy various materials that are normally available in floor 30 and above to reinforce your armor and gear way above what is expected. Here is a rule of thumb: your gear should be at the level is that allows you to climb to floor 41 and climb to TDM Diamond. If you are in TDM Platinum/Diamond at rank 40 or lower, your base is likely to be raided many times per day, so if you are bases are beefed up with uncapped gear and strong decals, you are likely to gain various defense wins.

While you are working towards Impregnable Fortress, you can work towards Flirting Virtuoso. During a raid, a defense fighter may randomly become unconscious while you deplete their health to 0, and while unconscious, these fighters can be picked up by your fighter, carried to the train, and then sent back to your bathroom for a capture. Unfortunately, you can only capture one fighter per raid, and you cannot complete a capture if your bathroom is full. Also, unless you have an active express pass, the trains only open at the 1:30 mark, and if you are in the waiting room, you have to defeat all of the defense fighters before you have access back to the train. So if you have an unconscious fighter on the train platform, you can forgo defeating the base to ensure you can make a capture; fortunately, you do not have to make a successful raid to have a successful capture so as long as you can carry an unconscious fighter back to the train. When you first unlock TDM, a temporary developer base is the first base you get to raid. Be ready for this encounter because this is the first and only guaranteed capture in the game. Getting a fighter to be capturable is incredibly rare, and there is no way to increase the capture rate. So you have to keep raiding. During a TDM war, you have a selection of targets based on your TDM Fighter Rank rather than your TDM rank, so you will have a selection of bases that are weaker than normal or even inactive bases. Just make sure you raid constantly, and to repeat, be on an active team so you have many wars and thus many bases to raid. If you stay at rank 2-3, you will likely be matched with other 2-3 rank bases that are normally easy inactive bases to raid with only 0-2 defense fighters; the tradeoff is that you have to go through the game using only grade 1s, and 0-2 defense fighters bases are less likely to confer a capture than a base that has more fighters.

You can also work towards Circle Crusher achievement. A successful raid involves you reaching at least 50% destruction while staying alive in 3 minutes, but for this achievement, you need to do 100% destruction. As long as you are in an active team, participate in every TDM war, and become comfortable with the combat system, you should easily get this achievement before the achievements above.

If your rank is too high i.e. you have read this guide after having purchased grade 6 fighters, your may not be raided and/or raiders will bring their strongest gear and consumables and will be ready for whatever you throw at them. At that point, you will have to rely on win-trading. If you go on Reddit or Discord, there may be other players willing to trade defense wins. A defense trade is simply raiding a base with the intention of leaving immediately or timing out/dying in the base. The former can only be achieved if you have an active Express pass; the latter can be achieved by sending a naked fighter and not touching your controls after the raid starts. Afterwards, the player will do the same for you. Depending on how active the player base is, this strategy may be faster than the main strategy since twinking in Let it Die takes a long time, though this strategy depends on the activity and charity of other players.

In order for this trade to happen, each player will need to be able to see each other. The most likely way to see each other is to be the same TDM rank (not TDM Fighter Rank), and the players on Reddit and Discord[discord.com] willing to trade are likely to be in TDM Diamond.

You can also use both the main strategy and alternative strategy simultaneously so as long as you can reach TDM Diamond with only grade 1, 2, or 3 fighters.

These other achievements can be missed, but they range from easy to tedious to complete. Once again, I have the most important ones towards the top of the guide.

Material World
500 equipped weapons/armor broken


The Nightmare is Over
Completed "Destroy the 4 FORCEMEN" quest.


Hoarder's Curser
Collect everything (Magazines, Mother Barb Songs, Stamps)


If you are not mindful to these aforementioned achievements. you may find achieving tedious to come back to and focus on these after beating the game.

Material World can be achieved as soon as you can safely clear Floor 1, but Material World can be tedious to focus on as you acquire fewer brittle equipment as you climb higher and higher. As you climb, the normal progression is to get blueprints from chests, you give these blueprints to the shop in your waiting room, you gather material to R&D your equipment, and then you buy the R&D equipment from the shop. This bought equipment are more tenacious than the equipment you find in chests or pillaged from the corpses of haters and screamers in the Tower. Therefore, this achievement is easiest on the early floors as you have very few blueprints in the beginning, so picking up multiple brittle equipment from the ground is a part of the natural progression in the beginning of the game. Getting this equipment broken will happen naturally if you are still getting used to the gameplay. Otherwise, if you are experienced or have made a far way through the Tower already, simply use Rage Move for your brittle weapons.

The Nightmare is Over
This achievement requires you to complete a quest in the game that becomes available after beating the game. Nonetheless, your time to completing this quest depends on your R&D up to this point. Completing this quest requires, while having the quest selected, beating all 4 Forcemen[letitdie.fandom.com] on Nightmare Difficulty. These Forcemen are available on specific days in the Tower, spread from specific floors 1-40. Beating the Forcemen efficiently require heavy R&D, specific decals, and/or specific weapons, and beating each one efficiently may require strategies that may be different what you have had to use to beat the game. Some Forcemen can negate many shroom effects, and most follow a different behavior pattern unique to them. You cannot brute force all of the Forcemen on Nightmare Difficulty unless you can climb to floor 300-351 with only minimal deaths. I will not go into specific strategies for how to tackle them. But I will point out what you can focus on during your climb in order to beat these Forcemen.

During your climb, try to gather enough points to buy the blueprint for Kamas RE[letitdie.fandom.com]. This weapon is an upgraded version than what you can find in the Tower, and it is helpful for beating some of the Forcemen easily. The most efficient way to gather these points is to recycle Premium decals, and the main way to gain Premium decals is to spend 50,000 Kill Coins to buy a random one from the Mushroom Club in your Waiting Room. Recycing is based on the rank of the decals[letitdie.fandom.com]. I would only recycle useless decals, but I will not discuss which ones are useless, as that can change. Instead, I recommend never to recycle a decal called "Payback". "Payback" is very important for efficiently beating Pale Wind, a Forceman. Nevertheless, getting either "Payback" or Kamas RE is going to take a while nonetheless, so it is something to focus on during your climb. Every spare 50,000 Kill Coin you have available in your bank should be used in the Mushroom Club to buy a Premium Decal. Not only does this chip away at the grind to finish this achievement but you only minimize how much Kill Coins you may lose from a failed TDM defense in your Waiting Room.

Bowling Crusher[letitdie.fandom.com], Lightning Wand[letitdie.fandom.com], and Pitching Machine[letitdie.fandom.com] are weapons whose blueprints you can find in the Tower. You may find these weapons neccessary for certain Forcemen fights especially if you have not acquired Kamas RE. If you have acquired and R&D Kamas RE, then R&D into the Pitching Machine may still prove useful for Red Napalm, another Forceman.

Hoarder's Curser
This achievement requires acquiring Magazines, Mother Barb Songs, Stamps[letitdie.fandom.com] from the tower. Mother Barb Songs are unmissable as you climb to the Tower.

Magazines require the collection of Yotsuyama Bionics Catalogue[letitdie.fandom.com] and Tales From The Barbs[letitdie.fandom.com]. Acquiring a magazine simply involves interacting with the magazine when you find one in the Tower. Some of their locations may be easy to get to and in plain sight; others may be annoying locations and may be hard to find. I will not discuss the specifics of each one. Some locations may only be available after you beat the game, so I would recommend just acquiring the ones you see along the way and look up those you cannot find.

Stamps[letitdie.fandom.com] are a bit special. Interacting with a stamp machine becomes a quick-time event with various timings. For the achievement, you need not worry about getting perfect or even good timing. Even if you interact with the machine and press nothing for the quick-time event, the stamp is consider acquired for the achievement. Some of their locations may be easy to get to and in plain sight; others may be annoying locations and may be hard to find. I will not discuss the specifics of each one. Some locations may only be available after you beat the game, so I would recommend just acquiring the ones you see along the way and look up those you cannot find.

These other achievements can be missed, but they are less tedious to achieve than the ones above or will happen along the way of achieving the ones above:

Mushroom Mania
Eat 1000 mushrooms


Murder Technician
Defeat 100 Haters


Champion of Barbs
Defeat all Jackals


LET IT DIE
Die 100 times


Mushroom Mania takes a while, but you will find that eating various shrooms helpful for bosses, haters, etc. Eating certain shrooms are almost required for some of the achievements above. Throwing mushrooms meant to be thrown does not count for this achievement. If you still do not have this achievement, you can just eat shrooms that are on the ground or are grown from dead haters/screamers.

Murder Technician may happen slowly as only one Hater spawn per floor, between 1-40. This achievement, nonetheless, is easily grindable via TDM, and this achievement will likely occur before any of the TDM achievements above.

Champion of Barbs is something you should save for after beating the game. The Jackals can be beaten before floor 40, but if you can easily destroy the last boss, defeating all three Jackals should be easy as well. These Jackals spawn on any non-Don floor that has no enemies. There are three different Jackals, and each one will only spawn once. The higher the floor, the more difficult the Jackals may become. I recommend spawning them on the first floor, and shoot them with the Kamas after throwing Frongus[letitdie.fandom.com] at them. The bullets from Kamas does not break the effect of the tear gas.

LET IT DIE is relatively easy to do. It may even be your first achievement if you are still getting used to the game. Nonetheless, if you find yourself under 100 deaths after beating the game, you can intentionally die in a TDM raid. Deaths in TDM count towards this achievement, and deaths in TDM do not cost anything.

These achievements you get as you progress and beat the game. Each of these achievements correspond to beat a Don.

At The End Of The Tunnel
Defeat Max Sharp


Deserted Town
Defeat Colonel Jackson


Dream's End
Defeat Mr. Crowley


The View From The Top
Defeat Taro Gunkanyama

If you have gotten this far already, I hope you have gotten all of the achievements or have been scared away from this game if you plan to get 100% of the achievements.
