XCOM Enemy Unknown Soundtrack - 08 Vigilo Confido - YouTube

I love the way this track ties in with the story. "Leviathan" shares the same intro as "Dig," but turns into something entirely different afterwards. It mimics how the player visits the same location several times, first while not having all the information about the dark machinations of the plot (Dig) and later when they have a bigger picture of the conspiracy unraveling (Leviathan).
