There are many Zoochosis endings to find and each are hidden behind New Game+. Whether it be through exploration or by picking a different dialogue choice, there’s multiple opportunities for you to venture down a new path, and alter your ending.
Officially, Zoochosis has 23 endings. There isn’t much variety in these endings however. Similar to No, I’m not a Human, Zoochosis endings switch out dialogue based on the choices you made in the game. There are only a handful of main endings that include different animations and unique conclusions that stand out compared to the others.
