Underworld: Endless War is a collection of three short, anime-style tie-in stories – whose creation was supervised by Len Wiseman, director of the first 2 Underworld movies and producer of Underworld 3 & 4 – each tell a different story, and at different periods of history to highlight new events of the Underworld mythology. These stories also tell of what happened before the events in Underworld: Awakening.
