Evaluation
Decay: The Mare launched on February 13, 2015 as a complete, self-contained package. The store description explicitly states the game is "available in one package, including an exclusive third chapter that will bring Sam's journey to an end." This language makes clear the game was designed and released as a finished product — all three chapters included at launch, with the third chapter explicitly framed as the conclusion to the story. There is no post-launch DLC, no announced future content, and no developer communications indicating any plans for additional content. The game shipped complete on day one.
