Ending Guide and Personal Order

PLEASE READ CAREFULLY:
In order to get the True Ending of the game you have to unlock the Zero Lost Ending first.
If you try to unlock the True Ending without witnessing the Zero Lost Ending first, the story will stop you and you'll unlock the Coffin Ending instead. Personally it is a waste of time to unlock this one since you'll unlock it anyway when you'll unlock the True Ending of the story and also you'll have to repeat the same rooms one more time. But for those of you who want to see this ending too I'll provide the guide down below.


Personal ending order:
1) Submarine Ending: Door 5, Door 3 and Door 2.
2) Knife Ending: Door 4, Door 7 and Door 6.
3) Ax Ending: Door 4, Door 8 and Door 1.
4) Coffin Ending: Door 4, Door 7 and Door 1.
5) Zero Lost Ending: Door 5, Door 8 and Door 6.
6) True Ending: Door 4 (Second Class Cabin choice: Take it), (Kitchen choice: It did seem rather odd), Door 7 (Operating Room choice 1: Know about ice-9? choice 2: ...Gave her the 4-leaf clover), Door 1.

[men acuatico promedio]

for a ds player like me with no flowchart this literally saved my life when i was doing all of the endings bro thx

[Mikki]

Ok nevermind, after reading the wiki again the steps are definitely the same as true ending... I legit thought the pointer in ending guides is only for the true ending. My bad LOL.

[Joxer]

I found 1 photograph with red and blue triangles)

[Joxer]

Thank you, appreciate it

[Leonhart August]

Joxer: The solution is in the triangles behind the picture frame found on the sink and the other two photographs with red and blue triangles. If you combine the blue triangles with the backside of the picture frame which has numbers 1-0 under the triangles you will get the combinations. You have to compare the triangles that you found under the pillow and the other one (which I can't remember where you find it) with the numbers and triangles from the backside of the picture which you need to unscrew with the screwdriver found in the stove.

[Joxer]

Why blue case's code is 0262 in 3rd Class Cabin?I decided by myself, but without gaming logic

[DreamDemon]

I wasn't saying the ending order was incorrect. I did the True ending and got Both that and coffin at the same time, doing everything else prior is correct. I was stating you don't have to do the puzzles over again, just go through each SCENE leading after you give Clover the 4 Leaf Clover, because dialogue changes ect. You need to activate all the different scenes and the correct option against Ace in order to get the True Ending. My friend was a bit confused at that part as I played through, he thought you could skip, I had to explain it to him. Other than that, the guide was very useful.

[Leonhart August]

DreamDemon also as far as I know by unlocking the Safe Ending before the Coffin Ending makes the Coffin Ending to be unavailable to unlock because by trying to unlock the Coffin Ending you'll end up doing the True Ending instead.

[Leonhart August]

DreamDemon for the true ending I only put the choices that are important in order to reach that ending. The other choices that you mentioned are choices which won't affect the flow of the story no matter which one you'll pick (I think). As for the puzzle combinations I'm gonna fix these. Thanks for helping!

[DreamDemon]

A little Clarification on the True Ending: Of course, do literally ever other ending except Coffin. You can no just use the flow chart to look at all the dialogue scenes, you don't have to repeat puzzles.

Door 4 > (2nd Class Cabin) Take Clover > (Kitchen) Act Curious (Ice 9)

> Door 7 > Talk about Ice 9 > Give Clover the Clover

> Door 1 > Option 1 Get Mad at Ace (This continues the conversation with Clover that Seven interrupted in the Laboratory > Collect Red Book (New Scene) > Look At the (Z)(E)(R)(O) Monitors Again (New Scene) > Obviously, the do the last scene you have available through the FLOW Chart, it also changes. Everything changes from there.
