Sub-Species Has Released a New Demo on Steam

Dive Underwater in Sub-Species

Independent studio Howling Hamster Entertainment has released a demo for Sub-Species, now available on PC via Steam. The game is an upcoming 2.5D multidirectional action-adventure shooter set beneath the ocean following an alien outbreak. The demo offers players a first look at the game’s 360° submarine movement, environmental exploration, and tense combat. You can also check out the official announcement trailer below to get a glimpse of the journey ahead.

In Sub-Species, players control a heavily armed submarine that rotates freely in any direction, navigating tight caverns, abandoned structures, and alien-infested zones. Combat relies on visibility, positioning, and momentum, pushing players to read their surroundings and react quickly under pressure. The demo introduces the game’s world through environmental storytelling and mission context. It sets the tone and hints at the larger mystery lurking beneath the ocean. All while leaving most of the story for the full release.

“We wanted the demo to feel like a complete experience, not just a tutorial,” said Creative Director Manus Burke. “It’s designed to let players feel the weight of the submarine, the tension of navigating hostile spaces, and how combat unfolds when every direction matters. By the end, you should have a real sense of what Sub-Species is about – and why going deeper is both tempting and dangerous.”

The game draws huge inspiration from classics like Sub-Terrania and Ecco the Dolphin, along with cinematic deep-sea sci-fi. Sub-Species blends retro precision with modern atmospheric design. The demo offers a glimpse into a world where every turn, movement, and decision can mean the difference between survival and annihilation.
