A low sci-fi with small horror elements fixed in — since the protagonist is a cultist killer — and an action adventure style plot that keeps going, making the players think there is only one ending, while they're actually fifteen.
I recommend it for the dialogue between characters and the unique style of storytelling it has for a choicescript game.
While I loved it, the seemingly unstoppable action plot may tire other more narrative-driven-story enjoyers.
Give it a try!
