Players do not need to own any older games to play Total War: Warhammer 3’s main campaign. Players won’t have access to all of the features because the Main Campaign and Immortal Empires are completely different. A separate campaign map called Immortal Empires requires both older games.
Yes, Total War: Warhammer 1 and 2 are required to play the Immortal Empires. You will also need to own them on the same platform (Steam, Epic Games, etc.) Immortal Empires mode contains a new map where all of the previous factions can fight each other. To play with the DLC factions from those games, you need both games and the DLC.
In Total War: Warhammer 2, this feature was called Mortal Empires. It’s essentially been redubbed the Immortal Empires for Total War: Warhammer 3.
Do you need to own Total War: Warhammer 1 and 2 on the same platform?
Yes, you do. It was confirmed in the Total War: Warhammer 3 FAQ that you definitely need the previous two games on the same platform. You also need to own the DLC on those platforms since the game cannot keep track of if you own any other versions of it in Steam and Epic Games Store.
Is Immortal Empires included in Game Pass?
The developers have not stated whether the Game Pass version players can participate in Immortal Empires. According to the information currently available, it appears the answer is no. This is only possible if Total War: Warhammer 3 removes the restriction that requires both previous games to be on Game Pass or simply allows the games to be purchased from that storefront.
