THQ and Volition has detailed their upcoming Saints Row 2, “Ultor Exposed”, downloadable content as well as release media of the upcoming download.

Tera Patrick joins the game as an Ultor microbiologist who wants to expose Ultor as the evil corporation they really are. The Saints, being Ultor-haters, are of course going to join in.

Ultor Exposed will also add four new multiplayer maps, two for Strong Arm mode and two for Gangster Brawl mode, six new vehicles, new outfits, and new hairstyles.

Ultor Exposed will release over the PlayStation Network and Xbox LIVE Marketplace on April 16th for 800 Microsoft Points ($10).

Some new screenshots were released, showing a new costume that reminds us of BioShock’s Big Daddy. Hit the gallery for the screens. The trailer can be seen here.
