Digimon Survive

You will unlock this at the end of part 12 of the main story on the Moral story branch. At the end of part 8, the story will branch off based on a choice. You will be prompted to save before making your decision. The options that appear during any particular playthrough are based on your Karma stats, divided into Moral, Wrathful, and Harmonious. In the EN version of the game (from what I have heard, the arrangement might be different for different regions), the Moral choice will always be the left choice, the Wrathful choice will be on top/top-right, and the Harmonious choice on the bottom-right.

After some testing, I have observed the following regarding the route selection:
1) The bottom selection is always available and

2) It appears that there are a total of 80 choices that can be made before this point which assign Karma.
3) During the selection, only the choices for your highest and second highest values will appear regardless of the actual numbers. (If they are tied 30/28/28, it will randomly select one of the 28s; If they are tied 29/29/28, you will receive the two 29 choices).

For instance:
On my first playthrough I had 65 Moral, 13 Harmonious, and 2 Wrathful and was offered the Moral and Harmonious route selections.
On my second playthrough, I had 15 Moral, 33 Harmonious, and 32 Wrathful and was offered the Harmonious and Wrathful route selections.
On my third playthrough, I had 10 Moral, 32 Harmonious, and 38 Wrathful and was offered the Harmonious and Wrathful route selections again.
On my 4th playthrough, I had 28 Moral, 28 Harmonious, and 30 Wrathful and was offered the Moral and Wrathful selections
When I reloaded and re-assigned to 28 Moral, 29 Harmonious, and 29 Wrathful, I was offered the Harmonious and Wrathful selections

In other words, in order to create a save point which gives you access to all three routes during one playthrough, you need to finish the climax fight of chapter 7 with 26/26/27.

Over the course of Chapter 8, there will be an additional 7 decision points before you get to the branch, so there is no way to end up exactly even, but you can save at the 6th decision point with a split of 28/28/28 and assign your last 2 points to access the route you want to play.

Note 1: From what I can tell, there is no way to access all 3 options at the same time, if anyone figures out something I am missing, please let me know so I can update the guide!

4) On a new game+ playthrough, if the conditions to unlock the Truthful route have been met

the same route selection choices will appear, but picking anything other than the bottom selection will lead to the Truthful route instead of the route it would normally connect to.

Note 2: Keep in mind that utilizing this method will cut off a lot of time from replaying chapters 1-8 multiple times, but you will not receive the carry-over bonuses from utilizing the new game+ system! This includes your progress towards Master Researcher achievement; however it is possible to obtain that achievement using only one new game+ save if you get all of the rare encounters over the course of the two playthroughs and grind free battles for slabs.

There are three main routes and a true route in this game. The three main routes are divided by Moral, Harmony and Wrathful. Many decisions in this game will offer you three choices with each of them increasing one of these three stats. Thankfully, you can tell which one will be increased by the way it's presented. In Karma choices, the left option will always increase Moral, the middle (top) will always increase Wrathful and the right will always increase Harmony. The game will notify you if any of these increase in the top right corner.

You can check your Karma stats by opening the pause menu and clicking Profile. Whatever one of these three stats is the highest is the route you will diverge on to later in the game.

For this achievement you need to ensure that Moral is the highest by choosing the left option as much as possible. It doesn't matter if you mess it up and add points to other categories you just need to make sure the one you want is the highest. The achievement will unlock once you complete the game.

This achievement starts when you choose "Be true to my friends" at the end of Chapter 8 and should unlock at the end of Chapter 12. You need "Moral" as the highest or second highest Karma Value.
There are some misleading guides that says "Save the World" as the Moral Route. "Save the World" is a green option, wich means HARMONY ROUTE. "Be True to my friends" is the RED OPTION, wich meas MORAL ROUTE.

TIPS FOR THIS ROUTE/MINOR SPOILER
This is a "Normal Ending", so everyone will stay alive. Get enough training with everyone, just don't forget to always train at least 2 free monsters to back up Agumon when you are alone. Gabumon and Renamon will join the team near the end of the game.
