MAP25: Demonic Hordes is the twenty-fifth map of the second release of Alien Vendetta. It was designed by Vincent Catalaá and Sam Woodman. It uses the music track "You Suck," the game over theme from Rise of the Triad. In the first release, it was MAP24, with the MAP25 slot taken by Valley of Echoes. Valley of Echoes was replaced in the second release by MAP24: Clandestine Complex, and Demonic Hordes was moved to the MAP25 slot. The level consists mostly of big battles with hordes of enemies teleporting in several areas as the player progresses through the level.
