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.
It also adds 4 optional crises to match the power of these megastructures, complete with their own lore for you to discover, thus keeping the game challenging and interesting to the end!


- 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.

- 4 new optional crises (1 midgame, 2 endgame, 1 post-endgame) to challenge the power brought by these powerful megastructures:
- The Katzenartig Imperium, a hypermilitaristic empire fielding an Attack Moon as their flagship.
- Aeternum, an extremely ancient Fallen Empire residing on a Birch World in the galactic core.
- The Compound, mysterious dark matter beings linked to the EHOF, hellbent on reshaping the galaxy in their image.
- The Blokkats, ravenous galaxy harvesters intended to fill the role of vanilla's mysterious Hunters.
They can all be disabled at game start if you do not wish to play with them.

- 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!

- 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.

- The possibility of discovering, exploring, and exploiting the Galactic Core and its supermassive black hole.

- 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.

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.

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: 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.

Overwrites vanilla megas to unlock the megastructure limits.

No Katzenartig Imperium Submod
