About Monster Slayer

Monster Slayer is an HTML adult adventure by It That Watches, presented in 2D CG art. You play a male high hunter who travels across dimensions to confront dragons, demons, and monster girls. The order treats them as targets, but the story lets you pursue them through fantasy, parody, and monster-girl encounters. Instead of killing every creature, the hunter can choose adult pursuits with these targets.

The current build is v0.9, a pre-final release dated October 11, 2026, and the latest listed changelog entry is v0.8.1. It runs on Windows, Linux, and Mac in English, with no censorship. The v0.8.1 update added two contracts, a Selyne quest linked to cosmic insanity and random sleep appearances, reworked endings, starting classes, unlocks and challenges, extra content for Nyxa, Deathclaw, and Naafiri, an expanded Oblivion ending, new items and scenes, and nine endings.

Developer's description

In Monster SLayer, you play the role of a high hunter, hopping across the many dimensions to deal with all manner of creatures. From dragons and demons to cute monster girls, none is innocent in the eyes of your order, but you have other ideas for these targets... Say, why would you slay these monsters when you can fuck them instead?

Review for v.61: This game is short and free to play in browser at the itch link. Rather than reading reviews, it is not much of a commitment to open another tab and play it. Good pregnancy focused games where…
