Steins;Gate Complete Walkthrough: Get All the Endings and Achievements

This is the choice of Steins Gate, but so is that one. Which one is right? Time-leap your way to the True ending with our full, spoiler-free guide.

Guide by Pete Davison, .

Steins;Gate is a considerably more complicated affair than most other visual novels.

This largely stems from its core gameplay mechanic: the "Phone Trigger" system. Rather than being presented with explicit, binary choices like in other visual novels, your interaction with Steins;Gate is entirely diegetic and performed through using Okabe's phone. The route you take through the game and the ending you get is determined by your responses to emails you receive, whether you make phone calls when given the opportunity and even whether or not you read incoming messages.

It's worth playing the game through at least once "on impulse" to see which of the endings you get before tackling the other routes. It is possible to unlock all the endings in a single playthrough with some strategic saving along the way, though, and that's what this guide is going to focus on. The most difficult route to unlock is, unsurprisingly, the "True" ending, as this requires you to take some very specific actions over the course of the story -- including several situations where you must choose not to act. Note, however, that triggering the flags for the "True" ending may prevent you from seeing some alternative scenes or reading different messages as the game progresses, so you may wish to indulge in additional playthroughs to clean up scenes you missed.

This guide, which should be mostly spoiler-free, was compiled with the help of the walkthrough on IBM5100.net and the flowchart from the Steins;Gate Wikia. As such, there may be some minor differences in the text you see. If you happen to spot any glaring errors along the way, please note them in the comments and we'll correct the guide accordingly.

The guide does not refer to decisions that don't have a major impact on the story or ending. If you are presented with an option not listed here, feel free to experiment -- save beforehand if you're worried!

Without further ado, then, let's begin. El Psy Kongroo.

Chapter 1

  • When setting the timer on the PhoneWave, enter anything other than "120#" 10 times for the "Homerun-level Clumsiness" achievement.
  • When you receive an email from Mayuri about "Upa," reply with "Upa" then open the attachment from the reply she sends you for the "RaiNet's Mascot" achievement.
  • When Faris emails you about "the final battle," reply with "Red Southern Cross" then open the attachment from the reply she sends you to make progress on the "Princesses of Chaos" achievement.
  • When Mayuri emails you with the subject "It's interesting," open the attachment to make progress on the "Hero of RaiNet" achievement.

Chapter 2

  • When you receive an email from Faris about "Original Sin level" reply with "2000."
  • When you receive an email from Luka saying "I made sweets" reply with "family."
  • When Faris emails you again, open the attachment to make progress on the "Songs of Chaos" achievement.
  • When Mayuri calls you, answer it.
  • When Luka emails you with the subject "My family" reply with "my sister."
  • When Kurisu calls (Okabe has her in his phone as "Assistant") answer it.
  • When Moeka sends you a message asking "Got info?" read it to see a scene with Kurisu.
  • When Luka emails you with the subject "About my older sister" you should get the "Cruel Sister" achievement. Reply with "you know."

Chapter 3

SAVE at the start of this chapter as there's a branching point with Faris' email messages.

  • When Faris emails you to say "PHANTASM is the cat's meow!" reply with "theme song" followed by "RaiNet Kakeru" on her next message to make progress on the "Hero of RaiNet" achievement.
  • Alternatively, reply with "PHANTASM" followed by "chaos" to make progress on "Songs of Chaos."
  • When Luka emails you "About frogs" reply with "Gero Froggies."
  • When Luka emails you with "more news about the frogs," open the attachment to make progress on the "Froggy Fad Demise" achievement.
  • When Daru calls, answer it to see a scene with him and Mayuri, or ignore it for a scene with Kurisu.

Chapter 4

SAVE at the start of this chapter as the choices for some achievements and the choices needed for the True Ending are mutually exclusive.

  • When Mayuri emails you about lotteries, reply with "magazine."
  • When Luka emails you about RaiNet, open the attachment to make progress on the "Hero of RaiNet" achievement.
  • When Kurisu emails you asking "Did you write it?" reply with "report" and, later in the chapter, "cup noodles" to receive the "Discontinuous Qualia" achievement. You will not reach the True Ending if you make this choice.
  • To trigger one of the True Ending flags, instead reply with "scientist" then later "bad scientist," "do better," "outsider," "disgrace" and "why am I still here?" to her subsequent mails. You'll also get the "Genius Girl's Melancholy" achievement.
  • When Suzuha emails you about Akihabara, reply "peaceful" and receive her next message to get the "Warrior Girls' Pride" achievement.
  • When Faris emails you about "Sign of increasing misfortune" reply with "he."
  • When Mayuri emails you about "Going out" reply with "Crunchy-kun."
  • When Mayuri emails you about Luka, which may be partway through the subsequent exchanges with Faris, reply with "Kakeru-kun" and open the attachment on her next message to make progress on the "Hero of RaiNet" achievement.
  • When Faris emails you again about "abilities" reply with "NyanNyanian" to get the "Cat's Tea Time" achievement when you receive her next message.
  • Alternatively, reply with "Chinchilla Star" then "Ep 8" to her next message, then open the attachment on the message after that to finish off the "Hero of RaiNet" achievement.

Chapter 5

No real branches in this chapter, but you will see some different scenes depending on whether or not you triggered the True Ending flag in the previous chapter. You may still wish to save if you're gathering achievements.

  • When Faris calls, answer it for a rather chuunibyou chat.
  • If you triggered the True Ending flag last chapter, Kurisu will email you about "plans." Reply with "traveling expenses" and read her next message (titled "Idiot!") to which you don't need to reply. Later, you'll receive another message from her, and this will unlock the second True Ending flag.
  • If you didn't trigger the True Ending flag in the last chapter, you'll get an email from Mayuri saying "what made me happy today" -- reply with "cosplay" and read the next message to get the "Passions Best Forgotten" achievement.
  • Alternatively, reply with "Fubuki-chan and Kaede-chan" then open the attachment on her next message to receive the "Princesses of Chaos" achievement.
  • When Faris emails you about "ComiMa," reply with "collapsing" and open the attachment on her next message to receive the "Songs of Chaos" achievement.

Chapter 6

SAVE! This chapter gives you the opportunity to reach an ending, and there are several different scenes based on the choices you make. Save if you want to see them all.

  • Shortly after the line "...Did it work?" you'll have the option to do nothing or call Mayuri. If you do nothing, you'll see an extra scene.
  • At the line "I should call or send a mail" call Luka for an extra scene.
  • At the line "I wonder how the other lab mems are progressing," call Kurisu, Mayuri or Daru for a scene with them, or do nothing for a scene with Suzuha.
  • When given the option to send the D-Mail at the end of the chapter, do nothing to reach Suzuha's ending and finish the game.
  • Alternatively, send the D-Mail to continue.

Chapter 7

SAVE! This is another chapter where achievement-related choices and True Ending choices are mutually exclusive.

  • If you've picked up the two True Ending flags available so far, Kurisu will email you about "The key." Reply "I don't have a key" then "frog" to her next message, then open the attachment on the message after that to make progress on the "Froggy Fad Demise" achievement. Then reload your save.
  • Now reply with "home" then "Hyahha" to her next message, then "I'm gonna give it to you straight" to the one after that, then open the attachment to her "Blazing heat!" message to finish off the "Froggy Fad Demise" achievement.
  • Alternatively, choose "I don't have a key" then "security" to her next message, then "reality" to the message after that, then read the final reply for the third True Ending flag.
  • When Daru calls, answer it for an extra scene.
  • When Kurisu calls, answer it for a scene with her, or ignore it for a scene with Faris.
  • When given the option to send the D-Mail at the end of the chapter, do nothing to reach Faris' ending and finish the game.
  • Alternatively, send the D-Mail to continue.

Chapter 8

SAVE! There's another ending to reach in this chapter.

  • If you've got the three True Ending flags up until now, Kurisu will email you. Read it, then read her next message later in the chapter for the fourth True Ending flag.
  • When you have the option of whether or not to call the PhoneWave (name subject to change) do nothing to receive an extra call from Daru.
  • After the line "Will you... remember me?" do not call the PhoneWave to reach Luka's ending and finish the game.
  • Alternatively, call the PhoneWave to continue.

Chapter 9

Only minor branches in this chapter. Save if you want to be thorough and explore all options.

  • At the line "Should I really leap now?" do nothing for an extra scene, during which Kurisu will call you. Answer it for another extra scene.
  • When Kurisu calls later in the chapter, ignore it for a scene with Moeka.
  • If you've got all four True Ending flags up until now, Kurisu will email you with the subject "Contact me, idiot!" Reply with "worried" and read her next message for the fifth True Ending flag.
  • When given the option to send the D-Mail at the end of the chapter, do nothing for an extra scene and CG.

Chapter 10

If you have no True Ending flags when you reach the start of this chapter, you're locked in to Mayuri's ending. Otherwise, you'll see either Kurisu's or the True ending.

  • If you have five of the six True Ending flags, reply "where you are" to Kurisu's message to lock in the True Ending.
  • When Mayuri calls, answer it for an extra scene.
  • Finally, your ending will be determined by how many True Ending flags you have. If you have none, you'll get Mayuri's ending. if you have 1-5, you'll get Kurisu's ending. If you have all six, you'll get the True Ending.

    Another example of an inscrutable title of a Japanese work. What's with the wandering semicolon?

    @kylekboyd50 No idea! Particularly given that when that phrase is used in the game, it's just "Steins Gate".

    I think it's just a quirk that Nitroplus and 5pb. put on that particular series; its predecessor and successor Chaos;Head and Robotics;Notes both sport errant punctuation too.

    Thanks Pete. That makes more sense, given that the creators have shown more than once that they have no idea how a semicolon is actually supposed to be used. :) Japanese doesn't use anything remotely like a semicolon, I presume...

    In the first chapter, you should also add that we should select "Kakeru-kun" in Mayuri's "Don't sell it >
