All Xenolith Plague Achievements + Walkthrough

Hi there! This is a full guide and walkthrough on the new achievements for the Xenolith Plague.

A big shout out to the community members who responded to my discussion post gathering info about how to trigger the different endings, you're all fantastic.

Also a huge thanks to Conit for their guide, I used it as a basis to make getting these achievements as easy as possible. Check it out below!

For those of you who are relatively new to Plague Inc. or perhaps have preferred unlocking genes through normal means, this is a well known method to easily unlock all the genes.

All you have to do is play Xenolith on Casual difficulty, then right before you are about to win save the game. After the victory screen you should unlock a random Xenolith gene. From there, load your save, win again almost instantly, and you have another gene unlocked. Repeat this method until all genes are unlocked.

For these achievements you will need Star Shards, Synpatic Pulse, and Void Signal.

I'll be using the exact same setup for all these achievements, so you can follow this part, save, get one of the endings you need, then reload. Here's what we'll be working with:

As with most plagues, we'll be starting in Saudi Arabia. Immediately grab the following upgrades:

• Lithic Seed
  
• Organic Bridge
  
• Subdermal Anchoring
  
• Mineral Leaching
  
• Skeletal Intergration
  
• Flash-Vitrification

Your upgrade tree should look like this

Go ahead and grab Volatile Isolation from the Humans tab as well. Next up grab the following upgrades:

• Lithic Fissures
  
• Crust Breach
  
• Ferrous Attraction
  
• Thermal Siphoning
  
• Tectonic Anchoring

Also grab the the two Atomic Reconfiguration upgrades from the Humans tab, the three humidity upgrades from the Abilities tab, and your upgrade tree should now look like this

Save the game here, from now what we do depends on which achievement we're going for.

For this achievement you need to shatter the planet into fragments using the meteor ability. It's definitely the easiest alternate ending to get in my opinion.

Continuing from our save file, get all of the following meteor upgrades:

• Gravimetric Tether
  
• Kinetic Impact
  
• Meteor Shower
  
• Meteor Storm
  
• Armageddon

Your upgrade tree should look like this

Now all you have to do is hit a single country with five meteors, and the planet will shatter, earning you the 'To Infinity and Beyond' achievement! The researchers shouldn't be a problem as you can see below

For this achievement, you need to awaken an alien conscience using the Crystal Alignment ability.

Continuing from our save file, get the all of the following ability upgrades:

• Crystal Alignment
  
• Atomic Bonding
  
• Field Persistance
  
• Local Amplification
  
• Tectonic Amplification

Your upgrade tree should look like this

From here you need to xeno-form 85% of the planet and use your Crystal Alignment ability on every continent at once. At first you can only store a single charge, with each use granting you a new charge slot. We need 5 charges, and we need the planet to xeno-form, luckily we can kill two birds with one stone here. Thanks to the Atomic Bonding upgrade infected people xeno-form the ground they're standing on when you use the Crystal Alignment ability, and with your Crystal Alignment affecting entire continents thanks to Tectonic Amplification you should be xeno-forming those pesky countries in no time. In order to spread the infection a little faster and slow down research, grab the following upgrades:

• Replicating Lattice
  
• Molecular Clevage
  
• Harmonic Field
  
• Lattice Optimization
  
• Ionic Displacement
  
• Seismic Liquification
  
• Piezo-Static Charge

Your upgrade tree should look like this

Since we don't want the whole planet to be xeno-formed, I would recommend leaving some of the islands alone, since you can easily hit 85% xeno-formed without them. If you already have everywhere xeno-forming, then simply devolve all of your crystal upgrades, the spread will stop dead in its tracks and give you more time to build up those charges. Once you have five charges ready, pause the game and use one on the following countries:

• USA
  
• Brazil
  
• Central Africa
  
• Russia
  
• Australia

Un-pause the game, and the ending should pop up along with your achievement!

Personally this was the most annoying achievement for me to get by far, but I've managed to streamline it here and make it as quick and easy as possible. You need to use the Shatter ability to emit a powerful void signal, and it requires you to shatter a large percentage of the population in quick succession. In order to spread the infection and xeno-form without killing too many people we'll also be using Crystal Alignment.

Continuing from our save file, get the all of the following upgrades:

• Shatter
  
• Cascade
  
• Resonance Cascade
  
• Crystal Alignment
  
• Field Persistance
  
• Local Amplification
  
• Tectonic Amplification
  
• Atomic Bonding
  
• Cellular Mimicry
  
• Metabolic Siphon

Your upgrade tree should look like this

In order to proc this ending you need a few things, 75% xeno-formation, at least one fully xeno-formed country, and finally to shatter at least 90% of the world's population VERY quickly. So for now, wait until a new continent has some infected people, use Crystal Alignment to make them xeno-form, and repeat until most of the world is infected, it shouldn't take long. Once nearly the whole world is infected, pause the game and Shatter two continents, I usually pick Russia and Brazil, but wherever you have more infected people is the best option. Un-pause the game, and the ending should pop up along with your achievement!

For 'Diamonds Are Forever' simply beat the plague on casual and get the normal ending, that is simply terraforming the planet 100% as fast as you can.

For 'There Can Only Be One', if you followed this guide to get 'Hello, World!' or 'Phone Home' you should have gotten this achievement at the same time since I didn't use meteors in either of them.

For 'One Vision, One Purpose' you have to beat the Xenolith plague on mega-brutal difficulty. You can use any ending to unlock this, but I would recommend Conit's guide that I linked in the introduction, it also unlocks 'There Can Only Be One'.
