Is there an official story length?
The developer confirms a prologue plus five main chapters, for six playable chapters in total. Official material also confirms main objectives, optional challenges, collectibles, difficulty choices, and alternate endings. It does not publish a standard number of hours. Campaign length therefore depends on whether a player follows only main objectives or also completes replay goals. A chapter count is verified; a fixed completion time is not.
The available playtime estimate
According to one currently available media review, reaching the ending while focusing on the main path took about two hours. That is a single reviewer’s result and is not an official average, minimum, or promise. A second media source confirms hands-on experience with the solo campaign but does not establish a universal runtime. A full-playthrough transcript captured story dialogue and the opening date, yet it did not state a standard completion time.
Why total playtime can be longer
Challenges, collectibles, score targets, difficulty options, and alternate endings can add repeat runs beyond a direct story completion. The official material presents these as replay features rather than a guaranteed hour total. Use “about two hours” only as one reported main-path sample. Not yet confirmed: an official average, a completionist estimate, or a chapter-by-chapter time table.
