Escape from Sixam
Description
A mothership was sent from the dying home planet to Sim's planet. From there, UFOs were sent to some worlds to prepare the planet for the arrival of the inhabitants of Sixam. Some of the aliens researched the Sims' genetics, others built robot armies, and in Willow Creek hybrids between Sims and aliens are created. The research results showed that children born on the planet are better adapted to air conditions. The hybrids appeared particularly robust. These would certainly make good workers once the Sims were removed from the planet.
While some worlds had already been invaded by the aliens or were still fighting for their freedom, other worlds were still believing that this alien matter would not affect them and that a diplomatic solution could certainly be found. The illusion of peace and freedom even makes some nations trade with aliens, even if they don't understand their customs. Aliens don't have family structures. Young adults meet weekly (if possible with a club) in a baby bar to produce the next generation in a resource-saving manner. The aliens' children do not grow up with their parents, but are raised by robots. Of course, one also condemns the actions of the aliens in other worlds, but as the aliens credibly confirm, they other sim nations started the fight and deserve to be destroyed.
It's your decision whether you play as an alien, robot or sim. You can follow one individual through live or play rotational.
Since this is mainly about aliens, the "Get to work" pack is of course needed. I also recommend the university pack for the robots. My save file contains many robots. However, you could replace the robots with aliens.
Like with all others save files you don't need them all, but I used all packs I have for building, so you could get a warning before playing that you don't own all packs, that's ok, just some things will be missing.
No CC! I used Tool and Build buy from Twisted Mexi and Ui cheat extension from Weerbesu. You don't need this mods to play this save file, but I want to give credit. I also used bb.moveobjects cheat.
I also recommend a mod that prevents Sims from other worlds from wandering into your world.

Update 3.0 11/12/25 11/12/25 added items and systems like custom venues for some lots from the adventure await and business packs. Also one new lot in the chestnut ridge with a spaceship

Your Sims can enter the spaceship teleporting with shift and click. Also, you have to go one level up to see the spaceship. If you run into trouble with a jumping camera, make the building deeper to the ground with the round arrows in build buy mode.
I hope you have fun with this, I certainty had.
