[Update #2]: Creative Assembly has now detailed the rather massive changes to Chaos corruption.
[Update]: Total War: Warhammer 3's newest and rather lengthy gameplay preview shows off the Chaos Undivided faction in action!
While this might not come as a massive surprise given the recent leak, Total War: Warhammer 3 devs have now come out to announce the final launch faction - Chaos Undivided led by a Daemon Prince of your own creation. To put it simply, by doing a variety of tasks to honor the four Chaos gods you'll be given Daemonic Glory, which can then be used to acquire thematic new body parts and weapons, as well as unlock new god-themed units to play around with!
Rather than babble on, allow me to share with you two of the recently posted trailers. They'll give you an excellent overview of just what this Chaos Undivided faction has to offer, as well as how awesome it truly is. Have a look, starting with the cinematic trailer and ending with the more in-depth preview:
The good news doesn't end there, however, as Creative Assembly has also revealed that there will be three campaign-based multiplayer modes to enjoy! 'The Realm of Chaos' will be the regular campaign playable with up to eight players, 'Darkness & Disharmony' will be a free-for-all sandbox focused on the daemonic invasion of Grand Cathay, while 'Something Rotten in Kislev' will be a smaller and faster campaign designed to be completed in a single session.
Besides all of these new features, you can also expect to see major improvements to some of the old ones. The always-frustrating supply lines mechanic will be getting toned down so you can field more armies, diplomacy will be getting a major overhaul so it's easier to understand and strike deals, you'll be able to issue ultimatums to factions trespassing on your territory, and the list goes on for a while. So long story short, Creative Assembly is really pulling out all the stops for Total War: Warhammer 3!
Once the next big announcement goes live I'll make sure to let you know. Until then, you can read a little bit more about all of the new reveals over at the official FAQ.
