Project Repo, now officially called Heli.os, is an immersive third-person roguelike videogame set in a future where humanity struggles to reclaim lost knowledge. Centuries after a world-scale disaster, scattered communities survive by salvaging old-world technology. Players step into the role of the Tinker, a researcher and explorer tasked with understanding and documenting forgotten machines, unlocking their potential, and using them to reclaim what was lost. At the heart of Heli.os is its modular component system, allowing players to collect, experiment with, and combine different mechanical parts to create unique abilities and tools. Combat is fast-paced and strategic, encouraging players to adapt their playstyle with each run. Between expeditions, the player’s knowledge is stored in an in-game journal, which they build over time by naming components, logging discoveries, and connecting clues. Inspired by solarpunk aesthetics, Heli.os presents a vibrant, hopeful take on a post-apocalyptic world. The game’s procedurally generated biomes (from flooded urban ruins to sun-scorched deserts) offer endless variety and challenge. With a passionate community already engaged, Heli.os is more than just a game: it’s an evolving puzzle, waiting to be unraveled.
