Achron can still be technically purchased, but the multiplayer matchmaking server has been shut down and Hazardous software has been offline since 2017.
The game is a really unique Piece of experimental software. It is infuriatingly complicated, further muddled by unintuitive controls. atrocious pathfinding, and some of the ugliest graphics I've ever seen. Despite all this, it would be nice to be able to breath some life into this genuinely unique RTS.
