Mount Circeo

Monte Circeo is a singleplayer location in Assassin's Creed: Brotherhood. It is the main location for the mission Hell On Wheels and is located just outside Rome. In the mission in question, Ezio must commander Leonardo's prototype tank, which he has been forced to build for Cesare Borgia, as well as destroy the plans for it. He must make his way towards Monte Circeo, where the device is being stored, by following the engineer but remaining stealthy the entire time; entering into Open Conflict with any guards will cause automatic desynchronization. The site itself is a small arms factory with siege machines stored in one end of the compound. The compound is protected by walls and appears to be heavily guarded.
