The following are strategy guides for earning the Watery Grave Achievement in the Shadow Plague DLC. Please feel free to add your own strategies, tips, and Q&A below:

Strategy 1Edit

Recommended genes:

1. Start anywhere except Turkey.

2. Evolve Therianthropy and Night Wraith and constantly keep your vampire moving from country to country. If it kills too many people and gets spotted, then the event will not occur.

3. Wait until a yellow headline appears in the News:

  • Caver in Turkey discovers deepest ever cave network

4. Evolve Shadow Blessing to start spreading your plague. You can also set up a Lair to get extra DNA points if you want.

5. Wait for another yellow news headline to appear:

  • Cavers expect to discover new species in Turkey cave network

6. After that, the following popup message should appear:

  • Shadow Pool discovered in Turkey

7. Wait for another popup to appear which reads:

  • Ancient human traces found by Shadow Pool

8. After that, wait until this message appears:

  • Shadow Pool hosts unique ecosystem.

9. Wait until the following two yellow news headlines appear:

  • Shadow Pool organisms baffle scientific community
  • Shadow Pool organisms 'billions of years old'

10. Reveal your vampire to the world by evolving Blood Rage and using it to harvest DNA in whatever country you like. Also evolve symptoms that increase severity and be sure to infect Turkey.

11. Do not destroy the Templars. They need to hold their position until this popup message appears:

  • First vampire 'came from Shadow Pool'

12. Now evolve Muscular Hypotrophy. Soon, Turkey will be filled with Shadow Slaves and the final popup should appear:

  • Templar mission to Shadow Pool fails

The achievement is now earned.
