Uchujin Haruo-kun explores a submerged world of clones
Uchujin Haruo-kun opens its Steam page with clone soldiers, submerged facilities and a death system that weakens them after every revival.
Uchujin Haruo-kun (宇宙人ハルオ君) is an upcoming third-person shooter with an unusually grim idea of resource management: keeping two clone soldiers fed, rested and alive while they search a submerged facility. Developer Moyashi Giken and publisher Waku Waku Games have now opened the game’s Steam store page, although there is no release date yet. 12
A drowned world to explore
The game takes place after war and climate change have pushed many cities beneath the sea. Players control Navy clones Kaede Kuratsuki and Kozue Kuroishi as they recover supplies from abandoned facilities. The ruins are not empty: old defence systems and dangerous experimental animals can turn a scavenging mission into a fight, while stealth offers a quieter way through.
Kaede is a half-beast clone who can carry more items and use every firearm type. Kozue is a medic with genetic-engineering skills, allowing her to recreate herself or Kaede after either character dies during an operation. That ability comes with a catch. Each replacement gradually worsens the clones’ genes, so repeated deaths make their abilities weaker and future missions harder. 1
Survival is more than shooting
Uchujin Haruo-kun also makes the characters’ physical condition part of the expedition. They need food to avoid fatigue and keep running, but eating too much can make them vomit. Players can even send them to the toilet before setting out, an unusually literal reminder that every trip into the ruins is supposed to be managed rather than simply blasted through.
The Steam page lists English, Simplified Chinese, Traditional Chinese and Japanese support, with full audio support noted for those languages. It also confirms single-player and full controller support, while the release date remains listed as “To be announced”. 2
Our opinion
The store-page reveal gives Uchujin Haruo-kun a clear hook without pretending it is ready to launch. Its submerged facilities and clone-decay system could make every failed run matter, while the food and toilet mechanics suggest a survival layer that is deliberately more awkward and specific than a standard shooter. The interesting question is whether those systems create meaningful decisions or merely busywork; we will need more gameplay and a release window before answering that. For now, the Steam page is open for wishlisting, but this is one to watch rather than one to play today.
