Endings

's Ascension ending (The Depths)
Survivor’s ending occurs upon reaching the Void Sea. Swimming down, a large number of s are seen, one of them taking interest in the and watching its descent. It reaches out a 'tentacle', hooking onto the Slugcat, before dragging them down at an incredibly high speed, then releasing them. After an undetermined amount of time, a bright glow appears, prompting Slugcat to swim towards it. Soon after, other identical Slugcats that follow the player's movement join them. Upon reaching the source of the light, a cutscene is triggered, showing Survivor seeing their family then completing their ascension.

's Ascension ending (The Depths)
The Monk's ending is similar to that of the Survivor's, though the ending cutscene is changed to show the Monk reaching their hand out towards Survivor.

The following endings are achievable after completing 's campaign, which permanently unlocks the Outer Expanse Gate for both Survivor and Monk.

's ending
This ending is achieved by reaching Journey's End as Survivor. The Survivor arrives at the Slug Tree, finding it abandoned, as the Slugcats that once resided there had now migrated. Depending on the number of Slugpups the player has at that point, the ending cutscenes are altered to reflect it.

's ending
Similarly to Survivor, this ending is achieved at Journey's End. Depending on whether Survivor's Outer Expanse ending has been achieved beforehand, the Monk either finds the Slug Tree empty, or the Survivor along with any Slugpups in their ending.
