OpenHellion is a multiplayer game set in space. You’re a part of a mission-gone-wrong to colonise the nearest star. The goal is to survive in space, and to do such you need to follow a series of quests; these will guide you through the core concepts of the game. The game is an open-world sandbox game, and allows you to build and manage your own space stations and ships. Join our Discord.

The project is based on HELLION by the Serbian company Zero Gravity. It is unclear who the current owners of the game property are, as the company that made it has gone bankrupt and there is little evidence of any buyers of the intellectual property. This project was started to let new people that never owned a copy of the game play it.
