Tactical level wargame based on Japanese animation series "Space Battleship Yamato"(also called Cosmoship Yamato or Star Blazers). This game revised from War Against White Comet, mainly improved missile combat and aerial combat rules, and added Dark Star Cluster ships and scenaros. Players manage a star-fleet of Earth Federation, Gamilus, Imperial Comet or Dark Star Cluster. Each ship unit represent a space warship, and each aircraft unit represent 9 to 20 space aircrafts. In each turn, players activate by random order for chit-pull engine. Activate number per turn is determined by Command Points and ship's energy value. Excellent ship like Yamato will activate more numbers than opponent per turn. Battle has three ways: fire combat, missile combat, aircraft action. You can also use super weapons like wave cannon with optional rules. Victory conditions are set for each scenario. The game contains 14 scenarios.
