The current Roblox Horror Spotlight page lists House of The Locust as a trending horror title, but does not publish a numeric rating. Rolimon's independent tracking shows 81.175% (rounded to 81% in many surfaces).
The 10.1% win rate reflects only the Escaped badge. With the Locust instant-kill mechanic, most attempts end at the keycard standoff, so the effective completion rate is bounded by audio-cue literacy and wall-gap access.
The wiki treats both metrics as community-tracked statistics. They are not surfaced as 'official' but are quoted as the most reliable public signal of run-difficulty in the current pre-alpha build.
