Hades' Star is a space strategy game about establishing and expanding an empire in a persistent galaxy. Players develop a home system around a Yellow Star, colonizing planets, arranging mining and trade, and confronting alien ships. Diplomacy adds a social dimension to that long-term planning: a system owner can grant other players access and set terms for mining, trade, or military cooperation.
Other star types reshape the rhythm of play. Red Stars are brief cooperative missions, where players work together against NPC ships, collect planetary artifacts, and escape before the system goes supernova. Corporations can also enter White Stars, five-day contests involving up to 40 players from two groups, with a Time Machine for planning moves and coordinating strategy. Blue Stars offer a sharper PvP contrast: five players each send one Battleship into a collapsing system and fight to be the last survivor.
Its systems range from negotiated access in a home star to tightly timed competition, so the number of players active at a given moment sits alongside a varied set of ways to interact.
