Alien Entity Hal-09 now has an official Steam page. Waku Waku Games opened the store listing on October 19, 2026, providing a much clearer look at the systems Moyashi Giken is building for the single-player third-person shooter also known in Japan as Uchujin Haruo-kun (宇宙人ハルオ君).
Players will not simply shoot enemies and retrieve supplies. Kaede and Kozue need to stay physically healthy during expeditions, while death carries a lasting consequence: they can be recreated as clones, but genetic deterioration gradually lowers their abilities each time the process is repeated.

Trailer, Steam Page, and Alien Entity Hal-09 Gameplay
Expeditions Are About More Than Shooting
Kaede and Kozue enter abandoned facilities to recover supplies, but wartime defense systems and abnormal animal experiments still occupy those spaces.
Steam also makes clear that combat is not always mandatory. Players can choose to put these creatures out of their misery or continue their search while avoiding detection.
Physical Condition Is Part of Survival
Alien Entity Hal-09 asks players to monitor basic needs as well. Kaede and Kozue need food to maintain their stamina, while overeating can cause them to vomit.
The game even asks players to consider restroom use before longer expeditions, extending preparation beyond weapons and inventory management.
Cloning Prevents Permanent Death—With a Cost
Most humans surviving in this world are clones, allowing Kaede and Kozue to be recreated after fatal incidents.
Kozue's genetic engineering knowledge makes that possible, but repeated cloning causes their genes to deteriorate. More deaths therefore mean weaker abilities and increasingly difficult future expeditions.
Hal Is the Central Mystery
Beyond recovering supplies, the pair are searching for Hal, a mysterious entity tied to an earlier project.
Hal is a half-plant lifeform built from assembled parts and DNA from Kaede and Kozue. The nickname comes from the HA-1_09 identification tag, while photosynthesis allows Hal to use water to recover strength when exposed to light.
Why This Matters
1) Death creates lasting mechanical consequences
A clone can replace a fallen character, but genetic degradation means failure continues to affect future expeditions.
2) Survival includes ordinary physical needs
Food, exhaustion, overeating and restroom use become part of expedition planning.
3) Kaede and Kozue have distinct roles
Kaede specializes in combat and carrying equipment, while Kozue's genetic engineering expertise powers the cloning system.
