Creative Assembly and Sega have shown off the latest Campaign Pack for Total War: Warhammer II.

As it’s name implies, the Curse of the Vampire Coast expansion focuses on vampire pirates and their legions of undersea horrors. The four new playable legendary vampire lords are racing to find the mystical Star-Metal Harpoon, which once imbued with power from an ancient sea shanty, will allow that lord to control Amanar, a great Merwyrm that has been ravaging the local sea lanes.

The new campaign is full of unique mechanics and locations based around the Lords of the Vampire Coast. These include Pirate Coves, upgradable flagships unique to each vampire lord, hidden Pieces of Eight that grant access to new undead pirate units, Treasure Maps, and much more. You can find an announcement trailer above.

To celebrate, the entire Total War: Warhammer franchise is on sale on Steam. The Curse of the Vampire Coast expansion will be out on Windows PC via Steam on November 8th for $18.99.

Here’s a rundown of the expansion:

Night falls on Lustria. As you stand on the dock and peer seawards through the gathering mists, strain your ears. The jungle sounds behind you fade, and in their place comes a wet thudding, as of rotten rigging against a mouldy mast. The sound multiplies, and with it, the groan of a thousand breathless voices, joined in something part-shanty, part-dirge. Dread prows pierce the gloom ahead, and the ghastly truth is laid bare: upon the ghoul-winds come the swollen hulks and decaying vessels of the Vampire Coast! Run now – run hard and fast. For it is all you can do.

It was the undying lord Luthor Harkon that laid claim to a stretch of Lustria’s east coast. Ever since, it has been a domain where the dead stir, leading expeditions into the jungle interior or setting sail across the Great Ocean to commit wanton acts of piracy. But the insane Arch-Commodore Harkon is not the only unliving admiral who takes to the seas with pistol-armed crews of zombies, vampiric depth guard, syreens and mournguls… there are other pirate lords who command dreadfleets of their own, packed to the gunwales with crews press-ganged into eternal service.

These tyrants ply the seas seeking plunder of blood and gold. However, now that the vortex of Ulthuan weakens, the captains search for more than mere treasure… for the Star-Metal Harpoon lies in the deeps, a weapon powerful enough to bring the greatest Merwyrm of them all to heel!

New Campaign Features and Mechanics:

Objectives

The great Merwyrm Amanar has been awoken from its slumber by the vacillations of the Great Vortex. It terrorizes the sea lanes, summoning vast storms and attacking coastal ports on a whim. Only one who wields the Star-Metal Harpoon will tame the beast and become immune to its ravenous hungers. However, the Harpoon must first be found, and invigorated using the three verses of a secret, ancient sea-shanty.

Each playable Legendary Lord must grow their dread reputation to become the most Infamous pirate on the seas. Certain opposing Pirate Captains know the three verses of the ancient shanty and, as your Infamy rivals theirs, they will seek you out in attempt to destroy you. If you best each in battle, you’ll learn each of these verses, all three of which are required to magically charge the Star-Metal Harpoon.

Only with the fully-powered Star-Metal Harpoon in hand can you embark on the final, fateful battle, bend Amanar to your will, and become the greatest sea-scourge the world has ever seen!

• Infamy
  As your faction wins battles, takes territory and establishes Pirate Coves (see Pirate Coves below), Your Legendary Lord’s Infamy grows amongst the ranks of pirate lords and ladies. This is the route by which you reach ultimate victory in a Vampire Coast campaign (please see Objectives above).
• Pirate Coves
  After a victorious port-settlement battle, Vampire Coast factions may choose a new post-battle option. Instead of taking, sacking or razing the port, the faction may choose to establish a Pirate Cove in the vicinity. These secret sub-settlements can siphon a steady flow of income from the main settlement, and bring other benefits related to any upgrades the player chooses to build in the Cove. The Cove can only be destroyed if the settlement itself is razed. In addition, a competing Vampire Coast faction which conquers the settlement may commandeer the Cove for itself.
• Upgradeable Ships and Building Trees
  Legendary Lords sail in their own unique ships. Details of these ship are accessed via the Lord in the same fashion as Horde Buildings for Horde Factions, and contain many powerful upgrades for the Lord and his army. This does not make them a standard Horde faction however. Vampire Coast lords may also occupy settlement like any other non-horde faction, and may develop it using the unique new Vampire Coast building tree. In short, they benefit from the best features of both Horde factions and Settled factions.
• Pieces of Eight!
  Carefully hidden around the world are eight unique golden tokens. Locating each and defeating its powerful guardian army will grant access to the Vampire Coast Regiments of Renown, powerful elite variants of units in the terrifying Vampire Coast roster.
• Treasure Maps
  Pirates of folklore buried great treasures around the world. As you win battles at land and sea, you may find the treasure maps marking their rough location. Solve the riddles that shroud them, and they can be yours for the taking…
• Unique Rites
  Vampire Coast factions gain access to four unique new Rites, granting a variety of bonuses. Curse of the Queen’s Cannon, for example, grants access to Queen Bess, a vast, one-off ship’s cannon which fires colossal cannonballs in a high parabolic arc, dealing tremendous area-effect damage and slowing those affected by the shockwave. Another, Curse of the Sea Mist, shrouds all your regions with a clinging maritime miasma, causing attrition to your enemies and granting Vanguard Deployment to your Monster units.
• New battlefields
  New Island Maps Broaden Total War: WARHAMMER II’s battlefield environments and, for the first time, players may now attack and defend Dark Elf Black Arks in battle, fighting with their assembled land forces on the lofty slopes of these vast seagoing structures. These new maps will be available to all WARHAMMER II players, regardless of Curse of the Vampire Coast ownership.
• Legendary Lords
  The dread Legendary Lords of the Vampire Coast will be revealed in due course…
• Unit Roster
  The horrific constructs, vast undersea beasts, ghoulish revenants and piratical hordes of the Vampire Coast will be revealed in full soon…
