"Steam rejected the build" at the finish line, the "last 3 months were intense crunch," and the story was finished 3 days before launch: How one dev scraped together a horror hit that "accidentally" sold 150,000 copies

Co-op horror game Emissary Zero has over 1,700 82% positive user reviews on Steam, where it's sold more than 150,000 copies and surpassed the expectations of its solo creator, who makes the game's development process sound like a string of helter-skelter production miracles.

In a hefty post to the game dev Reddit, indie soloist Rone Vine explains "How I made a horror game that accidentally sold 150k copies." Conceived as a linear horror game with optional multiplayer, Emissary Zero began as a distant Five Nights at Freddy's relative borrowing "things like surveillance cameras, dynamic obstacles, and roaming monsters."
