Gigastructural Engineering & More

Do you like megastructures? I sure do! This mod aims to expand on the concept of megastructures by adding more megastructures you can build, with a wide range of effects, and sizes ranging from large space stations to system-spanning constructs.


  • 45 new megastructures with a wide range of effects, including weaponized planets, microwormhole generators, stellar lasers, and system-spanning computers! The mod massively expands the endgame, adding dozens of new things to build, allowing you to shape the heavens to your will.
  • A menu with a custom UI, allowing you to individually select which megastructures you wish to use in the game.
  • 107 custom modded Achievements that can be earned during gameplay, and can give some rewards!
  • A new challenging midgame crisis, which can be optionally buffed if you want an even greater challenge (or disabled).
  • Several new origins that let you start on various ruined megastructures.
  • Unique systems, containing the ruined megastructures of the empires that came before your own, as well as other unique surprises.
  • The possibility of discovering, exploring, and exploiting the Galactic Core and its supermassive black hole.
  • A powerful endgame threat in the Galactic Core (Can be disabled).
  • A new endgame crisis related to vanilla's Hunters. (Can be disabled)
  • Improved AI that will use the megastructures as well.
