Description

Breeding Season Estrus takes monster-themed sci-fi beyond the home planet in a story-driven adventure from developer H-Bomb. A continuation of the original Breeding Season, this free game trades familiar surroundings for mysterious visitors, unusual alien species, and a galaxy with a surprising interest in your character’s expertise.

The story begins after the sudden destruction of your entire planet. Somehow, you survive—and awaken in the presence of a highly advanced being who traveled across the stars to find you. Recruited for your knowledge of monster breeding, you enter an interstellar journey where encounters with unfamiliar life-forms drive the narrative forward.

Breeding Season Estrus blends story-focused encounters with animated 2DCG and AI CG visuals. Its diverse cast includes monster girls, boys, nonbinary characters, and energy beings, giving the cosmic setting an unconventional personality. The appeal lies in discovering its strange inhabitants and following a survivor’s unexpected role in a much larger galactic story.

Version 0.1.5 offers a look at H-Bomb’s continuing sci-fi project, whether you’re returning from the original game or exploring its universe for the first time. Download and play Breeding Season Estrus for free.
