Description:

The mod offers players the chance to create and customize unique species on planets. It allows players to create entirely new species with their own traits and appearances, giving them the freedom to design creatures that match their imagination.

One of the standout features of this mod is the ability to regress planets to pre-FTL status. This means that players can reset a planet’s development back to pre-FTL, which can offer new challenges and opportunities for players who want to experience a different gameplay style. For instance, players can create a colony, “devolved it” with pops in there, and return as an “almighty god or savior” to this species. Allowing to have the experience with pre-FTL planets if you don’t have any available in your borders.

1. Research Life Engineering (available after Gene Banks).
2. Build Evolution Labs on any planet to get Life Breeders.
3. Use the decision on any planet within your empire to create a species.
   • If used on a colonized planet the species will be part of your empire.
   • Or you can choose to regress the planet to an ancient pre-FTL era.
   • If used on a non-colonized planet the species will become primitives (to an ancient pre-FTL era).
4. You get a prompt to choose which biological type the species will have. It might take a bit (in-game) time to create the species, but you will get an event as soon as it is done.

Usually this mod won’t break, so you can still run with the mod enabled. If you encounter a problem, feel free to report it here.

Yes, but for modded multiplayer, each player has to enable the same mods and have them in the same load order.

They are capable of it, but it is very rare (only xenophiles and/or materialists do). But each AI empire is limited to do it 2 times so they don’t spam species.

It depends. If the species is added to a vanilla species class, then it can occur that you create it (randomly). New species classes are not supported (except for colony regress or random selection).

• “Enhanced Gene Modding”: If you want additional customization options after gene-modifying
• “Premium Presapient Portraits”: If you want more naked presapient Vanilla versions of their species classes
• Smash or Pass: Species Phenotypes (minor – subjective – includes old Necrotic primitives)
• Premium Presapient Portraits: without adding new graphic files

Should work with 3.14.15 and beyond, if Paradox does not touch anything related to Primitives or Society Tech
