Campaign · Seeds of Ruin

Humanity went looking for its makers. Something answered.

Thirty-one missions in five acts, from a training sector on the frontier to the heart of the Root. The Kith are human in body, fused into a hive network, and they are not here to fight. They are here to harvest.

  • Scripted objectives, reinforcements, a betrayal in the fourth act
  • A final choice with three authored endings
  • Progress carries between missions; replay any mission you've cleared
A star detonates in a white and orange shockwave, tearing through its orbital rings while fleets flee along a route

Skirmish · A living map

The galaxy is an opponent too.

A fresh map every game in five shapes and any size, against an AI that builds, expands and attacks at four difficulties. Wormholes open shortcuts and collapse again. Stars flare with warning, then go supernova and take the system with them.

  • Six structures, from mining rings to shield generators and comm arrays
  • Fourteen upgrades across economy, military and defense
  • Fog of war, charted routes, five save slots and autosave
A spiral galaxy divided among six rival empires in blue, red, green, gold, purple and cyan, linked by wormholes

Multiplayer · Up to ten

Host a room. Share the link. Launch.

Play with friends anywhere in a browser, free-for-all or teams, with AI opponents filling the empty seats. Pick starting stars in turn, then the host launches. Nothing to install.

  • One invite link opens the join screen with the code filled in
  • Lobby chat, team setup and map settings before launch
  • The Windows build also hosts LAN games on your own network

How it plays

Every star is a colony to develop or a target to take. Territory becomes an economy; the economy becomes fleets.

Expand

Send your garrison down a route. Outnumber the defenders and the star is yours; leave it thin and it is theirs.

Build

Mining rings and solar arrays feed minerals and energy; research hubs unlock the tech tree; shipyards grow your garrison every turn.

Research

Warp drives, plasma lances, planetary shields, singularity refineries. Fourteen upgrades, three branches, real trade-offs.

Fight

Strength, defender advantage and technology decide every battle, and every battle is written to a log you can read back.

Ready when you are, Commander.
