About Red Siren: Space Defense
Red Siren: Space Defense is a space war game set in 2138, when mining colonies fight for control of planets in a distant star cluster. Exacorp forms the Red Siren combat squad to protect strategically important planets, and you take the role of a highly trained pilot. You fly starfighters to repel invasions, destroy ground forces and pursue enemy ships.
The interstellar war
Civil society and modern robotics have enabled private companies to colonize the planets and use their natural resources. Because the new mining technology is not available to everyone, groups build robots and loot planets, and conflict follows. You defend bases and planets against hostile forces in a war over the cluster.
Missions and combat
You fight tanks, robots, mechs, ships and battle walkers across challenging missions. Use bombs, a plasma gun, missiles and other weapons to attack enemies, dodge their projectiles and keep moving. You can approach combat with different strategies, including attacking enemies from behind.
Ships and upgrades
The game has four worlds, with new levels to unlock. You can try different ships and upgrade your ship and weapon arsenal, with ship types and upgrades suited to different play styles. Powerups can help you in battle, and completing missions earns prizes.
