OpenHV is a cross-platform open-source real-time strategy game set in a science-fiction future. It is based upon the game design and pixel art from Hard Vacuum, a game in development during 1993 that was never published. The artwork was published by Daniel Cook, who is also known for his work on Tyrian. It relies on OpenRA as game engine.

The game has seen several stable releases, but is still in active development.
