Plague Inc.: How to Awaken and Control Multiple Vampires in Shadow Plague

To awaken and control multiple vampires in the Plague Inc. Shadow Plague scenario, establish Blood Lairs for healing, unlock Therianthropy for flight mobility, and evolve through the Shadow Blessing transmission tree to activate dormant awakening traits. Expanding to multiple vampires allows you to attack fortified Templar Industries bases and spread your pathogen across separate regions simultaneously.

Step 1: Secure DNA and Establish Blood Lairs

Begin by keeping your progenitor vampire isolated in a country with lower medical capacity, such as regions within Africa or South America. Use Blood Rage to harvest DNA directly from local populations. Avoid evolving aggressive lethal symptoms during this opening phase so global health organizations do not initiate an early cure response.

Before unlocking new vampires, purchase at least one or two strategically placed Blood Lairs. Lairs provide two operational benefits:

• Passive DNA Generation: Lairs continuously feed points into your DNA pool over time.
• Sanctuary Healing: Wounded vampires recover health rapidly when stationed at a Lair without consuming active ability resources.

Place your initial Lairs in inland territories away from active Templar activity. This gives newly awakened vampires a nearby haven to retreat to if targeted by military strikes.

Step 2: Unlock Secondary Vampires Through Shadow Blessing

Once your progenitor vampire has established baseline defense and Therianthropy flight, transition from isolated feeding to host conversion:

1. Evolve Shadow Blessing: This transmission trait alters human hosts rather than consuming them, seeding the pathogen into local populations.
2. Spread the Infection: Allow Shadow Blessing to build an infected host base in surrounding territories.
3. Trigger Awakening Traits: Once the prerequisite infection conditions are met, awakening nodes appear on the evolution grid. Purchasing these traits summons secondary vampires in infected territories.

Do not trigger awakenings if your progenitor is critically low on health or if you lack the DNA to unlock Therianthropy immediately for the newly spawned units. New vampires spawn with base survivability and will perish quickly if caught near established hostile installations without an escape route.

Step 3: Coordinate Combat Against Templar Industries

When Templar Industries establishes bases to counter your pathogen, deploy your vampires in coordinated strike rotations rather than massing them in a single territory. Templar bases deploy countermeasures that steadily damage attacking units.

To destroy upgraded Templar bases without losing a unit:

1. Engage the target base with your primary combat vampire using Blood Rage.
2. Monitor that vampire's health bar. When health drops to half, disengage and fly via Therianthropy to the nearest Blood Lair.
3. Immediately send a fully healed secondary vampire into the territory to continue attacking the base before its defense resets.
4. Rotate the recovered progenitor back into combat if the fortification requires sustained pressure.

Step 4: Secure Isolated Islands and Avoid Drone Strikes

Leaving any vampire stationary in an active Blood Rage state flags that territory for targeted military airstrikes and drone attacks. Shift your active units regularly between tasks to prevent rapid bombardment.

Use secondary vampires to bypass late-game port and airport shutdowns:

• Fly a vampire directly into closed island territories such as Greenland, Iceland, or Madagascar.
• Trigger a short burst of Blood Rage to establish a local presence, followed by Shadow Blessing to infect the native population.
• Reposition the vampire to an adjacent mainland territory or Lair once transmission begins, ensuring the pathogen spreads without relying on open transport lanes.
