Soundtrack composed by Frank Klepacki
The appropriately named "Divine Intervention" is probably the most epic piece of music off the Universe at War soundtrack and sounds like something delivered straight from the heavens. I never really got into the Masari soundtrack with the exception of this particular track. Who are the Masari you might ask? Ah, well they're the third major faction that you get to play in Universe at War: Earth Assault (I say "major" because us Humans are pathetic compared to the rest).
The Masari are an ancient and advanced race that apparently uplifted the Hierarchy. When the Hierarchy turned hostile against the Masari, a small group of them fled to Earth and sought refuge there. They instructed humankind in order to become a powerful force to oppose the Hierarchy in the future and inspired many ancient mythologies. Their ship the Atlatea sank beneath the waves and went into stasis (obviously inspired by the legend of Atlantis). The Masari end up helping Humans in the defense of Earth.
The soundtrack was originally offered for free off the Petroglyph forums but you can download a copy from the Free VGM section at Choicest Games. It's also available for streaming off Frank Klepacki's website.
