Underkeep Play Demo

How Long to Beat Underkeep (2026)

The developer’s own figure is 15 to 20 hours for a completion, and about 30 hours if you chase exploration, puzzles, and side threads. The studio’s press release repeats the 15 to 20 hour line, so that is one originating source.

Why this is one voice, twice

The FAQ and the Games Press release come from the studio. Counting them as two independent stopwatches would be dishonest, so the status column says “same developer”. The Pro Game Guides review talks about combat and party building and skips the clock. I am not converting “it feels long” into a number.

The demo is a different clock: 15 to 30 minutes for the opening area and one dungeon. That slice is not a percentage of the 15-hour claim, because nobody published the chapter count.
