The estimate comes from a direct developer answer
The Wccftech interview is the source for the roughly 20–25-hour estimate. The retained document describes its scope as a solid completion run. That wording should stay attached to the number instead of being replaced with a more specific category the research did not define.
A developer estimate is useful for planning, but it is a different kind of evidence from a completed-player timing sample. The file does not retain an independently measured average. This guide therefore attributes the number rather than presenting it as a universal result.
100% is described as taking longer
The same interview distinguishes a solid completion run from a longer 100% run. That supports a difference in scope. It does not supply an exact numerical duration for full completion in the retained material.
Do not calculate a 100% time by adding an invented allowance to the estimate. The research does not provide a measured ratio or a verified checklist to justify that calculation. The useful statement is simply that the developer expects the more complete run to take longer.

Player guesses are not an independent average
The source file includes a Steam player discussion about length. Its notes explicitly say that the player guesses do not independently verify the developer estimate. The discussion is therefore excluded from the factual playtime figure.
A small collection of expectations is not the same as timed completions. This page does not average speculation or convert discussion replies into a tested campaign length. The developer’s attributed estimate remains the only supported numerical answer in the retained research.
The demo cannot establish full-campaign time
KONAMI’s announcement establishes an opening demo. That opening scope cannot determine the duration of the whole campaign. The researched Steam listing also does not supply a verified completion-time average.
Use the demo to judge whether the opening experience suits you, not to calculate an exact full-game duration. The source file does not establish that later areas take a predictable multiple of the opening. This page therefore avoids extrapolating from demo time.
How to use the estimate
For planning, the retained developer estimate is roughly 20–25 hours for a solid completion run. Keep the pre-release attribution and the completion scope visible. Treat 100% as a longer undertaking without assigning an unverified number.
If your search is specifically about a main-story average, that narrower timing category is not established here. A reliable player average needs completed-run evidence and a clearly defined scope. The guide preserves the source’s estimate instead of relabeling it to answer a different question.
Sources and research date
This article uses the material retained in the October 13, 2026 research. Official descriptions, developer statements, and hands-on observations are identified in the section references. Details are scoped to those sources and are not a claim of independently completed retail testing.
