We are pleased to announce that Stronghold: Warlords will include the series' classic Free Build game mode, allowing players to put their stronghold to the test with AI invasions. In Free Build players design a castle with near unlimited resources, customise its defences and finally launch wave after wave of invasions, putting their creation to the test.


Free Build is designed to be played in many different ways. A selection of large open maps to choose from, each with picturesque scenery and monuments, will allow players the option to simply build to their hearts content if they desire. As in the main campaign, skirmish mode and multiplayer the titular Warlords mechanic can also be used to help build their dream citadel, sending key resources and providing buffs to their castle economy.


Invasions will come with a host of options, including a selection of unique siege armies to throw at your castle walls. Test your mettle against everything from squads of tribesmen and stealthy ninja to battalions of cavalry and armoured legions with powerful siege weapons. The challenge can be further modified with invasion difficulty settings and the ability to add random events such as peasant revolts, moth infestations and deadly roaming tigers. Players will also be able to create custom Free Build maps, adding their own events, invasions and warlords to capture.
