根据我的测试，有六个结局与该成就相关，他们也有单独的结局成就：
1) Luke Skywalker
2) Shoulda Took Off
3) Surname Frank
4) Everyone's Waifu
5) Tyler Durden
6) Murdering Mass
注意，你并不需要为同一个结局做不同/对立的故事线
比如，石油大亨与特许经营权线都对应Shoulda Took Off结局，但只需要做一次即可

There are six endings related to this achievement, and all of them have individual achievements.
1) Luke Skywalker
2) Shoulda Took Off
3) Surname Frank
4) Everyone's Waifu
5) Tyler Durden
6) Murdering Mass
Note that you do not need to make different/opposite story lines for the same endings.
For example, both the Oil Tycoon and Rancher Franchise story lines lead to "Shoulda Took Off", so just choose one side to complete the game.

由于成就界面并不能告诉你离解锁还差什么，所以我们需要一点特殊技巧。
打开存档文件夹，以win11为例，位置在
C:\Users\your username\Documents\Westerado DB\saves
你会看到global.sav文件
ISCII或者UTF8编码都可以使其可读，可能会有些乱码，但并不影响阅读。
这是一个全局存档文件，记录了已解锁人物、已记录结局和设置等内容。
请放心，我们不需要修改存档，所以不用进行备份。现在打开它。
现在我们需要知道就是哪些结局被记录了，sav文件并不是像成就名那样记录结局，下面揭晓谜底！
1) Luke Skywalker——war stars
2) Shoulda Took Off——not leaving
3) Surname Frank——Indian lovers
4) Everyone's Waifu——all the wife
5) Tyler Durden——club fighting
6) Murdering Mass——horde Mode
上面就是存档中与结局一一对应的关键词，这样你就能知道哪些还没有被记录。
现在，只需要拾遗补缺即可！

Since the achievement page won't tell you the achievement progress, we need some special skills.
Open the save folder. Here is the location (My operating system is Win 11):
C:\Users\your username\Documents\Westerado DB\saves
Then you will see global.sav.
ISCII or UTF8 can make it readable. It may have some mistaken codes, but it does not matter.
It is a global save file that records the unlocked characters, recorded endings and settings etc.
Rest assured, we do not need to modify it, so we don't need to keep back-up copies. Now open it.
The global.sav doesn‘’t record ending as its achievement name. But we need to know which one are recorded.
Here's the answer!
1) Luke Skywalker——war stars
2) Shoulda Took Off——not leaving
3) Surname Frank——Indian lovers
4) Everyone's Waifu——all the wife
5) Tyler Durden——club fighting
6) Murdering Mass——horde Mode
There are the keywords corresponding to the ending in the sav file, so that you can know which one hasn't been recorded.
Now let's go for it!

为了确保能够100%获得成就，最好关闭云存档并清除save文件夹中的内容来重新开始。
游戏愉快！
