About SpaceInvasion
SpaceInvasion is a strategy game about building colonies, developing technology and fighting for control of the universe. You expand planets, manage resources, assemble fleets and plan attacks, while other players shape the universe through their actions. The game includes multiple universes, with thousands of players and events running around the clock.
Build your empire
Explore solar systems containing up to 16 planets, scout and spy on rivals, claim debris fields and expand each planet with mines, factories, shipyards and defences. Mine resources to grow an interstellar economy. Kryptonite is harder than metal and is used in many things; spice is the most valuable raw material, fuels ships and is essential to technological progress. Thermosolar plants produce energy but require large amounts of spice.
A tech tree unlocks stronger ships, buildings and abilities, while specialisations let you focus on areas such as the economy, military or espionage. The Synth network offers 347 connected nodes with different play-style mechanics, allowing you to plan a build and specialise your empire. Technologies and structures include teleporters, which send fleets to your planets without delay; galaxy scanners, which detect fleet activity in solar systems; and the Quantum Array, which provides the synthetic computing and fabrication capacity for the Synth upgrade path.
Build and command fleets
Design and combine dozens of ship types, plan attacks and fight rivals in tactical real-time battles. Missions such as saves, recycling runs and attacks can be followed live as they travel across the universe. Ships include small hunters, an evolution of the small fighter; warships, with better armour and stronger weapons than small fighters; versatile Phoenixes with strong protective shields; and Destroyers, feared for their onboard weapons.
Transport and support ships include small and large transports, colony ships and recyclers. A Recycler carries 25,000 units. Other ships and defences include Starcruisers with diffusion engines and heavy laser cannons, Battleships equipped with EMP cannons and warp technology, partially cloaked stealth bombers, the Imperial starbase, the Titan Carrier, the Void Shield, the Doombringer, the Transmitter and spy probes. Spy probes report on enemy planets, with more detailed results available at higher technology levels. Solar cells convert sunlight into energy, with efficiency based on solar radiation and distance from the sun.
Alien threats
Alien attacks and black holes that warp galaxies threaten the universe. Powerful alien bosses also appear, seeking to conquer the galaxies. You can hunt them down and face their effects across entire galaxies.
Multiplayer and events
Team up with other Spacepilots to coordinate wars and compete for the top ranks. Regular events, contests and limited-time universes offer exclusive rewards. Nexus Raid is a more RPG-style mode in which you build a fleet of tank, healer and damage ships and take on aliens alone or in a team of five.
Tools and records
Community tools include a battle simulator for testing attacks and defences, a flight calculator for working out routes and arrival times, and a Synth calculator for browsing the skill network. Leaderboards and battle archives include the Hall of Fame, which ranks Spacepilots across every universe, and the Battle Hall of Fame, where you can revisit major battles and replay them blow by blow.
