Does your species prefer the warm glow of an irradiated planet? Whether you "accidentally" nuked your homeworld or evolved to feed on radiation, this mod will help you bombard "terraform" planets into tomb worlds. This includes applying orbital bombardment graphics to any planet being "terraformed" to a tomb world.

As of Stellaris version 3.5 "Fornax" and the Toxoids expansion, the game has built-in a variation of terraforming planets to tomb worlds, but only for empires that are Relentless Industrialists and only after having completed a special project. This mod allows all empires to access it with a lower cost, but with higher research prerequisites. Thus you may rarely see two options to change a planet into a tomb world if your empire has the Relentless Industrialists study completed - that is a feature and not a bug.

Adds terraforming links to change almost any colonizable, non-artificial planet into a tomb world (pc_nuked). Empires whose founder species has one (or more) of the Tomb World Preference, Survivor, Radiotrophic, or Irradiated traits (nuked empires) do not require any special technologies to "terraform" into tomb worlds. Non-nuked empires must have at least 1 Pop of a nuked species and the Tomb World Adaptation technology. Converting unhabitable worlds (barren, cold barren, or frozen) that have the Terraforming Candidate modifier always requires the Climate Restoration technology.

These new terraforming links allowing them to "terraform" planets into tomb worlds. Supported "terraforming" transformations:

• All nine basic habitable planet classes plus gaia planets
[list]

• One-quarter the normal cost to terraform a world into a different category (e.g. dry to wet or cold)
• Nuked empires and Memorialists can use tomb world "terraforming" without first researching Terrestrial Sculpting
• Non-nuked empires must have at least one Pop of a nuked species as well as the Terrestrial Sculpting and Tomb World Adaptation technologies
• Shows the planetary bombardment graphics while "terraforming"

Hive and machine worlds

• One-half the normal cost to terraform a world into a different category (requires more bombs "terraforming devices" to remove)
• Nuked empires and Memorialists can use tomb world "terraforming" without first researching Terrestrial Sculpting
• Non-nuked empires must have at least one Pop of a nuked species as well as the Terrestrial Sculpting and Tomb World Adaptation technologies
• Shows the planetary bombardment graphics while "terraforming"

Barren/cold barren/frozen worlds with the "Terraforming Candidate" modifier

• Standard cost for barren
• Standard high cost for cold barren/frozen
• Requires Climate Restoration technology

[/list]
Planets converted to tomb worlds this way are not eligible for the random events that can sometimes occur on tomb worlds - there's no mystery about what happened, it was bombed "terraformed" on purpose. Non-nuked empires that have already "terraformed" a planet into a tomb world waive the requirement to have at lease one nuked Pop.

Built for Stellaris version 3.6 "Orion." Not compatible with achievements.

Only adds new terraforming links, so it should not conflict with other mods that do not also add terraforming links from and to the same planet classes. Does not support new planet classes added by mods such as Planetary Diversity, but will still work for the base game's planet classes.

"Terraform" to Tomb World: Planetary Diversity Compatibility adds support for planet classes added by Planetary Diversity. Almost all of them can now be "terraformed" into Tomb Worlds.

Inspired by Tomb World 'Terraforming' by SingABrightSong and the new Radiotrophic trait added in Stellaris 3.1 for owners of the Plantoids Species Pack. Radiotrophic plantoid and fungoid species have decreased upkeep cost and a population growth rate increase on tomb worlds, so would also benefit from the ability to "create" tomb worlds. The original mod has not been updated, so I created this enhanced and expanded version.
