About this project
What does Space Insaiders add?

Hello everyone! I'm back with a new project adding space planets, tools, armor, weapons, vehicles, and more to the game! Let's get started!

About:
As I said, the modification is a collection of several planets that we can visit by opening a new window under the "M" button! The planets are full of new enemies, bosses, and much, much more!

Planets:
Gluxo:

Hixon:

Plaxonia:

Trehaxo:

Jhilhail:

To survive in space, you need to wear the right clothes to prevent oxygen depletion! The fun is all about finding new structures on each new planet, facing new bosses, and restoring peace in Space Insiders!
New Bosses:
Zao:

Griarh:
K' Asentre:

Dronehr:

Khaloh:

Hodern Smaller (The Main Antagonist):

Ending:
Finally, I would like to add that I am still working on the modification, so there may be minor errors that I will try to fix in the future, so I invite you to install it and positively evaluate the project!
