Which TotalWar games have Multiplayer coop campaigns?

Recently I got TotalWar Shogun 2. I am playing multiplayer coop campaign with a friend and love it. Sometime later I got TotalWar Troy and discovered it has no multiplayer coop campaign...

So my question is

Which TotalWar games have Multiplayer coop campaigns?

Solution 1:

Every Total War game since Empire has had a 2 player coop campaign:

• Empire: Total War
• Napoleon: Total War
• Total War: Shogun 2
• Total War: Rome II
• Total War: Attila
• Total War: Warhammer
• Total War: Warhammer II
• Total War Saga: Thrones of Britannia
• Total War: Three Kingdoms

CA has said multiplayer campaigns will be added to Total War Saga: Troy at a later date
