dangerous passage through the Andes. They discover the Inca city in Pacamayo Valley and defend it from the Circle. Amelia soon finds that Beaumont has once again escaped, this time with the barrels of the Fountain's water. Amelia and Kanyenke next fight the Circle at their last stronghold, the Ossuary, in Cuba. After they destroy the Ossuary with help from Havana, Beaumont ambushes Amelia and Kanyenke, but Amelia shoots and kills him. She then uses the Circle's stored treasure to revive the Falcon Company and builds railroads to the future west coast of the United States. Back in the US, an elderly man congratulates Amelia and states that she broke the Circle in one lifetime, hinting that he is Morgan Black and that he greatly extended his life using water from the Fountain of Youth. Development Technical features Age of Empires III builds on and introduces new features to the Age of Mythology engine, called Bang! Engine. One new feature is the inclusion of the Havok physics simulation middleware engine on the Windows version and the similar PhysX engine on Mac OS X. This means that many events such as building destruction and tree falls will not be pre-created animations, but will be calculated according to the physics engine, in an innovation for the series. Other graphical features of the game include bloom lighting and support for pixel shader 3.0. Audio The Age of Empires III original soundtrack features an original musical score composed by Ensemble Studios musicians Stephen Rippy and Kevin McMullan, whose previous work includes other games in the Age of Empires series as well as Age of Mythology. It was released on November 11, 2005, by Sumthing Else Music Works. Stephen Rippy, music and sound director at Ensemble Studios, said, "Age of Empires III is a game with an epic topic — it covers the colonization of the Americas over a period of some three hundred years, so it needed to have an epic-sounding score to match. Using a full orchestra and choir as well as some more period-inspired instrumentation, the music follows the story of Morgan Black and his descendants as they battle the Circle of Ossus for a foothold in the New World." The soundtrack also features a bonus DVD that includes fourteen tracks remixed in 5.1 surround, a behind-the-scenes video of the studio session, the Age of Empires III cinematic trailer and five exclusive
