OpenHV

OpenHV resurrects Hard Vacuum, an unreleased 1990s pixel-art sci-fi real-time strategy project originally conceived by game designer Daniel Cook. Rebuilt from the ground up on the robust OpenRA engine, OpenHV transforms those lost retro assets into a fast-paced, polished, standalone tactical RTS.

Set in a harsh, corporate-dominated sci-fi universe, three asymmetric factions—the militaristic Hegemony, the agile robotics of Dystopia, and the heavy corporate defense forces—clash over vital alien resources. Players harvest mineral fields, erect sprawling power grids and production plants, and deploy combined-arms forces of mechanized infantry, stealth hovercraft, and heavy artillery walkers.

Because OpenHV is built on OpenRA, it inherits two decades of modern RTS infrastructure: crisp high-resolution UI, modern zoom controls, fluid pathfinding, customizable hotkeys, intelligent attack-move commands, and robust online netcode with dedicated public servers.

With both single-player skirmish modes against adjustable AI commanders, handcrafted map packages, and an integrated map editor, OpenHV delivers the pure, unadulterated joy of golden-era RTS warfare without legacy compatibility headaches.
