The space war has begun!!
About
Year XXXX. On that day, ordinary life was shattered. Aliens from a planet 300 million light-years away invaded Earth. Their weaponry far surpassed human technology, resulting in the death of half the population. However, through the use of modern armaments, humanity managed to successfully repel the first wave. To prepare for the next assault, humans analyzed and reverse-engineered the crashed alien spacecraft, eventually gaining the ability to construct their own starships. The Global Space Defense Organization (GSDO) has constructed a total of 200 starships. These ships are categorized into three types: "Assault Ships" (similar to battleships) "Escort Ships" (primarily for protecting Assault Ships) "Motherships" (large-scale vessels serving as carriers and command centers with various functions)
