----MORTAL EMPIRES UPDATE (Michael.Whelan | October 25 2017) 
----
The first update for Total War: WARHAMMER II hits via Steam auto-update on 26/10/2017 and contains a host of changes, tweaks, improvements and fixes (please see below for details). Mortal Empires, the new grand-scale campaign encompassing the landmasses of the Old World and the New World, will become available as the update goes live. Download it for free here!
Mortal Empires requires ownership of both Total War: WARHAMMER and Total War: WARHAMMER II to play. Once downloaded, Mortal Empires will appear as a new playable campaign in the WARHAMMER II campaigns menu, alongside the Eye of the Vortex campaign.
Including all the core Races and Legendary Lords from both games, Mortal Empires also allows you to begin a campaign as any DLC or Free-LC Legendary Lord from the first game. Going forward, it will also encompass any DLC/FLC Legendary Lords that are subsequently released for WARHAMMER II.
The one exception is the Norsca Race Pack (Wulfrik the Wanderer and Throgg the Troll King). These have yet to be implemented and will become playable in a future update. The same update will also implement the 30th Anniversary Regiments of Renown, Old World Legendary Lords skill adjustments, and other changes and additions which first appeared in the Foundation Update for Total War: WARHAMMER 1.
INSTALL SIZES AND MORE
Due to the unique way Steam patches games – by backing up your existing installation, applying the freshly-downloaded data to the duplicate, then deleting the old installation, if you ever wondered – you may need to free up some hard drive space to install Mortal Empires. Here’s what you can expect:
Mortal Empires patch download size: 	~4.5 GB
Mortal Empires Campaign download size: 	~713 MB
WARHAMMER II pre-patch installation footprint: 	~40.5 GB
Total disk space required during update installation (includes 44.5 GB temporary files for installation process):	~85 GB
WARHAMMER II post-patch installation footprint: 	~42.5 GB
If you’ve limited space on your primary hard drive (for example, if you’re using an SSD with limited space as your primary drive, with a secondary mechanical drive for mass storage), a useful workaround we’ve found is to setup a secondary Steam Library folder on your storage drive. Provided you have enough space on your primary drive for the final installation (see ‘post-patch installation footprint’ above), Steam will automagically utilise any other registered Steam folders on other drives as a download location for the install process.
To set up a secondary Library folder in Steam, Click Steam->Settings->Downloads and click the Steam Library Folders button. From here you can create extra Library folders on any of your drives.
BLOOD & GORE
This update also introduces the Blood for the Blood God Effects Pack to Total War: WARHAMMER II. This is free for players who bought the pack for Warhammer 1. Players who own WARHAMMER II but not the first game, and therefore not the first Blood for the Blood God Pack, will need to purchase the pack to access its grisly effects.
Blood and gore effects can be toggled on and off in the advanced graphics options menu. Hail Hydra!
UPDATE NOTES (highlights)
This update comes with a number of tweaks, improvements, changes and fixes to many areas of the game, along with our first major balance-pass for the WARHAMMER II core races. We’ve also made some tweaks to the Free For All MP mode, added a host of new FFA maps, and introduced new buildings and dilemmas for the different Races.
Read on for the full details, but first off, here are some headline fixes we feel may be relevant to players’ interests:
* FIXED cases of units dropping attack orders (and therefore not pursuing fleeing enemies)
* FIXED units in guard mode stopping attacking if current melee enemy Rampages
* CHANGED Morathi and Malekith’s skills to spread the owning faction’s corruption, instead of starting faction’s corruption. This means that if Mortahi is confederated to Malekith’s faction, she will not continue to spread Chaos corruption
* FIXED multiple region borders that were preventing factions from being able to trade with one another, especially if their capital was on an island
* FIXED Screaming Bell being incorrectly marked as a small unit. It is now correctly considered a large unit
* CHANGED the difficulty of the final battle when initiated by the AI (by completing their fifth ritual). The battle will now feature an additional army led by the race’s other Legendary Lord
* CHANGED Black Arks from being part of the army upkeep penalty. Black Arks now do not factor in to the Supply Lines modifier
* FIXED Blessed Units not receiving the effects of certain Technologies, Skills or Astromancy stance
