The Star Swarm demo for Windows is now available on Steam, offering the chance to experience Oxide's Nitrous Engine, a 64-bit cross-platform strategy game engine that's been described as "stunning." This is not a game, but a tech demo of the Stardock-funded project (the Steam page calls it a "benchmark"), described thusly: "Star Swarm is a real-time demo of Oxide Games’ Nitrous engine, pitting two AI-controlled fleets against each other in a furious space battle. Star Swarm shows off Nitrous’ ability to have thousands of individual units on screen each running their own physics, AI, threat assessments and pathfinding." Word is this is optimized for AMD Mantle (due today, but not yet available here), but it is not required.
