Deus Ex Machina

To ease completion of this achievement, the player can save their game while inside the final room. In this room, Eliza will present the player with three switches and a passageway to a fourth switch, each switch corresponding to each of the different possible endings. The player can choose an ending, reload the game to this save point, and then select a different ending in succession until they have watched all four possible endings.

Alternately, the player may choose to play through the game from start to finish four separate times to earn the achievement.
