OpenHellion was founded in autumn 2022 in an attempt to reverse-engineer HELLION back into a fully-functioning Unity project. As more errors were fixed, more got uncovered, which caused more and more rewriting.

The orginal game, HELLION, was developed by the Serbian company Zero Gravity. Development on the game started in 2015, but because of an ineffective development process, the game had to shut down in 2019. During the shutdown process, the game was made free in a short period of time, before being taken off Steam completely.

In spite of this, an active community composed of dedicated fans kept the game alive. Not long after the shutdown, a person started a project to fix many bugs, and in the long term rewrite and fix unfinished portions of the game. This person chose to organise this in a very autocratic way with closed source and no way for volunteers to help. OpenHellion on the other hand aims to be as open as possible, with the ability for everyone to join if they wish; but most importantly, you can fork the repository if you want to.

We have a roadmap for some of the features we want to implement.

In December 2022, Zero Gravity Games was liquidated. This has resulted in uncertainty around the intellectual ownership of the game. This project is non-commercial and voluntary, but if any of the rightholders feel their rights have been infringed, they have a right to have their work removed from the repositories. If you are the current rightholder; please contact me on discord (makkkkus) or by email (nygardboi (at) protonmail.com).
