I mean, the treasure one has to be the treasure ending, cause you get the two tied up WITHOUT the treasure if you confront Mara in the lobby without help. Maybe if you find the treasure before you subdue Mara?

Apologies, adding those two to the gallery was a mistake on my end. Both of them were used in the game at one point but have since been removed.
The image of Veleno is the original game over art for the closet in Abby's office. It was replaced with the image of Veleno standing near Abby with her hair wrapped around him.
As speculated, the treasure game over was part of the Mara ending. To be honest, I don't know what happened to that one. It was fully integrated at one point but I lost track of it.
