Paradox Interactive have released the Toxoids Species Pack, the latest DLC for their hit sci-fi 4X game, Stellaris.

The Stellaris: Toxoids Species Pack adds new Origins, Civics, Traits, and cosmetics based around surviving in harsh, toxic environments like Twitter. These include traits for living on inhospitable planets full of irradiated toxic wastes, or exploiting your own planets without caring about long-term consequences.

Many of these mechanics allow you to gain massive bonuses, but come with harsh drawbacks as all the caustic, carcinogenic goo starts to reduce your population’s life expectancy in subsequent generations.

You can find a launch trailer below:

The Toxoids Species Pack is available for $9.99.

You can find a rundown of the new Stellaris DLC (via Steam) below:

Rise from the primordial ooze all the way to the stars and stake your claim with the hardiest, most stubborn species in the game’s history with Toxoids, a Species Pack bubbling with visual and mechanical additions to the myriad worlds of Stellaris. Empires featuring the Toxoids species can grow and adapt faster than most creatures, but tend to make life unpleasant for their neighbors – and often for themselves. Toxoids will feature*:

• New Origins:
  • Knights of the Toxic God: In the depths of your homeworld, rumors rumble of a true power buried under the toxic sludge. Do you dare to dredge up the secrets of your past – and potentially unleash them upon the galaxy?
  • Overtuned: The candle that burns the brightest, burns itself into the galaxy’s memory! Play as a species that can gain more and more traits at the cost of its own lifespan, and live for today without worrying about sticking around for tomorrow!
• New Civics:
  • Toxic Baths: Grow your population fast with a fresh infusion of mutagenic sludge – so long as you’re willing to tolerate the costs to your planet and your people!
  • Scavengers: One empire’s trash is your empire’s treasure! Don’t be too proud to harvest debris and destruction for quick construction projects of your own.
  • Relentless Industrialists: If you’re going to keep up with demand, you’re going to have to learn to ignore all of those petty regulations and negative opinions. The surviving population will thank you for all of the resources you gain!
• New Traits:
  • Incubator: Repopulate quickly when your planet is empty, but those growth facilities can fill up fast!
  • Inorganic Breath: Your own people are a source of valuable exotic gasses! It’s a shame the respirators are so expensive.
  • Noxious: Other species can’t stand being around you, and it seems like your mere existence is making your planets awful places to live. On the other hand, other empires have a very difficult time wanting to fight or subjugate you, and it’s hilarious to see the look on their faces when you’re in the room!
  • Exotic Metabolism: You’ve adapted to ask “are you going to eat that?” where other species would be calling the hazmat team. Eat faster, live longer, and enjoy a terrifying rainbow of flavors!
• New Cosmetics: Species portraits, ship models, and cityscapes that only a mother could love.
• New Advisor: Grow your empire alongside a relentless source of noxious sarcasm

The base game for Stellaris has been available on Windows PC, Linux, and Mac via GOG and Steam.
