What happened
Red Thread Games has highlighted Hello Sunshine on its own website and on Steam as a new game for PC. In the official text, the studio calls it a mystery survival game for one or two players, with a Steam release planned. The Steam page and the official website use the same core description and both point to a game that is not yet available.
The setting revolves around the remains of a corporate empire. According to the description, players must stay in the shadow of a giant robot during the day and remain close enough at night to stay warm. The game emphasizes gathering, crafting, and upgrading, while presenting the world as a place where machines never shut down. The official summary also explicitly refers to a survival mystery RPG, positioning Hello Sunshine as a mix of exploration, survival, and progression.
The available information does not include a release date or even a release window. Both the Steam page and Red Thread Games' website use the label "coming soon." The provided sources do say the game is coming to PC and that players can wishlist and follow the title on Steam, but there is still no concrete date.

Background
Hello Sunshine is presented in the official description as a survival mystery RPG for PC. The core loop centers on scavenge, crafting, upgrading, and surviving in a world ruled by machines that never power down. The setting is explicitly tied to the ruins of a corporate empire, giving the game an industrial, post-apocalyptic feel.
The studio also states that the game can be played solo and supports co-op for two players. The official text refers to a game for one or two players, but the provided source material does not explain how that co-op works in practice. The role of "The Final Employee" is also not further clarified in the supplied information.
The available official descriptions do place strong emphasis on the day-and-night cycle. During the day, players must stay in the shadow of a giant robot, while at night they need to stay close enough to keep warm. That positions Hello Sunshine as a game where survival is directly tied to the environment and the presence of machines. The official text also says players must "piece together" the world, suggesting that the story or worldbuilding is revealed in fragments.
Comparisons to Journey and a Wall-E-like premise have circulated, but those comparisons come from reporting rather than a direct official statement from Red Thread Games in the provided source material. What is clear is that Hello Sunshine has been announced as a Steam game, that it is coming to PC, and that the official channels still label it "coming soon" without a concrete release date or window.
