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.





The EHOF by Kreitani has been integrated into this mod!



The mod, as said above, adds 44 new megastructures.

Please note that they might require more balancing, so feel free to point out something you think isn't right.
It is recommended to have a look at the documentation.

As there are too many megastructures to describe every one of them individually, please check the mod's gallery for each megastructure's description.

All megastructures can be individually disabled if you do not want to use them.

Q: Is this the mod with the megastructures teased in the reddit?
A: Yes.

Q: I wanna add something to the mod!
A: If you'd like something you made to be in this mod, simply friend me and we can discuss it!


Overwrites the "habitable_structure" scripted_trigger, so might mess with some mods that also overwrite it. Should still work mostly fine.
Patch to fix the issue

Mods that add new resources will not display them properly in the topbar.
Patch to fix the issue

Real Space System Scale will cause problems with the models, such as clipping or exploded ringworlds.
A patch is available on the workshop.

Overwrites vanilla megas to unlock the megastructure limits.

No Katzenartig Imperium Submod

Have fun building Gigastructures, and don't forget to rate and comment.

However, I will ignore negative comments that just say "This sucks". Please give constructive criticism! If you think the mod deserves a negative review, please elaborate on why and how it can be improved, so that the mod may be made even better.
