My favorite franchise is coming out with an expansion! Medieval 2: Total War Kingdoms is the expansion to the best-selling Medieval 2: Total War.

Key Features

• Four new, epic campaigns that give you the chance to rule Britannia, fight for the Holy Land in The Crusades, take the side of Christendom or Paganism in The Teutonic Wars and become leader of a brave new world in The Americas.

• 23 playable factions including Ireland, Wales, Norway, Mayans, Apachean Tribes, Chichimeca, Tlaxcalans, Tarascans, Kingdom of Jerusalem, Principality of Antioch, Teutonic Order, Lithuania and Novgorod.

• Over 150 new units, including the devastating Greek Flamethrower, Canons of the Holy Sepulcher, Mounted Thunder Braves, Lithuanian Arquebusiers, Dievas Guard, Magnelwyrs and Mayan Hornet Thrower.
• New siege weapons include burning oil to devastate the enemy at the gate and fearsome mangonels to rain fire down on your foe.

• Control multiple armies in battle. For the first time in a Total War game you can now take command reinforcement armies to overwhelm the enemy and strategically turn the tide of war to your advantage. Create forces to compliment your main army, or use your reinforcements to coax the enemy into an ambush.

• New hero characters with powerful new battlefield abilities such as Richard The Lionheart and Saladin. Lead your armies into battle with heroes that can truly turn the battle your way. Deploy them wisely on the campaign map, choosing the key battles in which to utilise their influence and abilities.
• A huge array of historical characters and events bring the past vividly to life like never before. Witness the emergence of William Wallace to push back the English forces in the Britannia campaign or explore the New World as Hernan Cortés in the Americas campaign.

• Build permanent forts to garrison troops in preparation for an invasion or seize control of key strategic points to inflict increased devastation upon the lands or your enemy. Fight battles within and against moated forts for the first time.
  

• New technology trees influenced by Religion and Prestige. Worship your Gods and convert the population to unlock new structures, technologies and powerful units in the Teutonic campaign. While the in the Americas campaign, as New Spain, you must win the favour of the Motherland to raise your profile and earn yourself the technology and units you need to conquer.

• A host of new mission types. Assist in the formation of the Baron’s Alliance as you seek to pin back the English in the Britannia campaign. Protect and earn a much needed donation from crusading Nobles as the Teutonic Order in the Teutonic campaign.
• 6 New Multiplayer scenarios and 20 new Custom Battle maps offer stunning new locations to wage war on.

• Go head-to-head with a friend in the Hotseat multiplayer mode and put your leadership skills to the test in the Kingdoms campaigns or Medieval II’s Grand Campaign.

there's so much stuff here this sounds more like a complete game but you do need Medieval 2: Total War installed to use this expansion. Looks like a late August release. I can't wait!
