THQ announced today that the upcoming Saints Row 2 DLC, Ultor Exposed, will be delayed. It was supposed to arrive tomorrow but now it'll be released on April 23rd.

Ultor Exposed adds three new story missions featuring porn star Tera Patrick. She's playing an ex-Ultor scientist who helps you expose the dirty little secrets of the Ultor Corporation. The DLC also includes a competitive cooperative mode, four new multiplayer maps, new character customization options, and vehicles.

"This [new release date] is to co-incide with the public launch of the Red Faction: Guerrilla singleplayer demo," a THQ rep told SPOnG. "The Ultor Exposed pack includes Red Faction inspired content including a vehicle and outfit right out of RFG so we wanted to sync them up so gamers can enjoy both at the same time."
