As Generation 167 is about to begin, an unexpected visitor arrives in the skies of Sagan 4. Aliens have come to Sagan 4.

Major predators above 1m in size have a 50% chance of going extinct.

Size changes can be doubled. (A 2x normal boost becomes a 4x boost)
Atavism genes can now reach ancestors ancestor regardless of # of generations


Hybrid species between unrelated macroscopic organisms, because of the alien experiments, are much more likely to occur for this Gen only.

Hybrid flora species slots 0/10 filled
Hybrid Fauna species slots. 0/5 filled
Microscopic Life has spread to Mason by these aliens.
Revived Life: A species previously thought extinct has been brought back to life.
0/5 slots filled

Luckily the invaders will move on at the end of this Generation, But their impact will be felt for millions of years to come.

Oh, and by the way,

That's the only extinction criteria? that would make it the least deadly mass extinction lol

I figure anything big and predator would probably get hunted down. Should the % be higher then, like 90-100%?

Actually not a bad idea imo for extinction event.

All the impact of a sophont species but none of the hassle evolving it.

how about instead we have an extinction event where a sophont evolves and plays sburb, thus bombarding Sagan 4 with meteors the size of the moon and wiping out all life on the surface and replacing the biosphere with carapacian exiles

the aftermath might be more interesting with fewer survivors

Gosh, why didn't the Nauceans set up Sagan 4 against alien invasions? Or the real-life administrators explicitly establishing the the planet is in a remote backwater galaxy no alien invaders would ever want to enter? Or a lonely universe where the Nauceans and Sagan 4 sophonts are the only sophonts to ever exist?
