About this Mod

The Aliens are here! 👽
And they came in peace.... unless you mess with them, of course.
This new species can be found in a new structure, their spaceship: The UFO. This structure spawns at the highest Y coordinates in your world! They also appear in certain End biomes (for now).
Features of the Mod
🛸 Structures:
The UFO
This otherworldly spaceship spawns between the Y coordinates of 200 and 250.
It's also only a little rarer than villages, so don't worry about missing out!

👽 Mobs:
The Aliens
This new species of mobs is a lot smarter than you think! They are as cute as they look; however, you must not harm them, or you'll face the consequences.


🔫 Items:
Ray Gun

Deals three hearts of damage and doesn't require any ammo.

🆕 Update Roadmap
1.0 - Aliens and UFOs
Initial Mod update, introducing its main elements.
1.1 - Otherworldly Weapons
Focused on adding the new weapon (and preparing space for others), but also on fixing bugs.
1.2 - Ufology
This update will add more to the mod's worldbuilding, centered mainly on the new villager profession and new structures.
1.3 - Homeworld
Certainly the most challenging update. It will feature major changes centered on The End, such as a new biome and larger structures. As well as an overhaul of already established concepts.
⚠️ Known Bugs
- The painting can't be accessed by inventory
- Firing with a gun triggers the default right-click animation
Stay tuned! And keep an eye on the sky, they are watching us. 👽
