This achievement is automatically unlocked when you unlock your 47th achievement. Although some of the achievements in the game have been glitched, as of this writing, this achievement has not been. There are zero tracked gamers with 47 achievements indicating the achievement is not glitched since unlocking 47 achievements unlocks this achievement as the 48th. I will monitor the stats and provide an update if this changes.
Although it is very possible to earn all achievements through normal game play
, there are two missable achievements:
--Supreme Support Weapons
for upgrading all pods if you neglect to pick up a Powerup Part S after you defeat a stumpy peculiar robot in the City Ruins. This is a one time event. The drop is a 100% certain drop but you must pick it up. If you do not do so, you will be short one item required to upgrade all pods.
for seeing all endings is missable if you defeat a secret boss without first obtaining the Y ending. You must survive an encounter with the boss until a timer begins counting down. To get the Y ending you must allow the timer to expire. If you defeat the secret boss and continue with the game, you will have no other opportunity to fight the boss and get the Y ending.
Note that both the above achievements can be bought at the special achievement shop. So, unless you have a personal goal of not using the achievement shop, there are no missable achievements
Following your third playthrough, a secret achievement shop is made available. You are alerted to this shop when you complete your third playthrough. At the Resistance Camp, interact with the Strange Resistance Woman--she has a spherical head and is sitting down. The second to last dialog choice is "Request unlocking you-know-what
." When you select it you bring up the "Secret Shop
This is a shop that sells 28 numbered achievements numbered from 20 through 47. This achievement is not one of the 28.
The achievements you have already earned are shown in red as being sold out. When you move over achievements, you will see the description on the right except for secret achievements. Secret achievements will have a question mark in place of the achievement icon in the description box. The text will read:

The earliest opportunity to unlock this achievement is to use the achievement shop. It is a personal choice whether or not you use the shop. Using the shop is the fastest way to get this achievement. If you decide to use the shop, the following is a recommended approach: Play through three story playthroughs as quickly as possible. Then, load the save file made after your third playthrough. When you load it, you will see a new feature--chapter select.
Under chapter select, choose Chapter 17-09: 9S and A2
. Choose the character you did not select in your third playthrough. When you finish the chapter, you will get either the C or D ending to complement the C or D ending you got during your third playthrough. In other words, you will now have obtained both the C and the D endings. The credits will be interrupted and the pod will ask a question. Answer yes to continue playing and trigger the [E]nd of YorHa route. Answer no
to any question that states or implies you should give up. Eventually, the game will power you up and you will be able achieve the E ending.Caution: After the The Minds That Emerged achievement pops for completing the E ending, you are asked if you would like to help other players. Make sure you answer NO. Answering yes will delete all your data--all your saves, weapons, quests, items, data, and so on.
If you take the most direct route, therefore, you will unlock at least 19 achievements story related unmissable achievements. You may unlock more. For example, It is difficult to progress through the story without shooting down at least 255 enemies. So you will, most likely unlock Ruler of the Skies for doing so.
Load up a save file made after the third playthrough. Use chapter select to select any chapter where you can go to the Resistance Camp. Chapter 03-04 MIA is a convenient one. In the Resistance Camp, make sure you have plenty of cash. If you don't have enough, you can sell chips and items to the Supply Trader. You may want to make a save if you have a slot that you don't really need. Then, interact with the Strange Resistance Woman--and choose "Request unlocking you-know-what
." Use your cash to buy all remaining achievements.
If you don't have enough cash, you can do this in increments. An achievement, once unlocked is permanent. So, you do not have to save your progress after unlocking the achievements and it is advisable not to. Instead, either go back to the title screen and repeat the process, this time buying the achievements you left on the table from before. Or, if you made a save after selling your items, load it up and use the cash to buy the remaining achievements.
This achievement will unlock immediately following unlocking your 47th achievement. Again, you are free to use the shop as much or as little as you want or not at all.
