The new era of peace in Mortal Kombat 1 survived its first challenge, but it couldn't last. In the latest expansion announced with a trailer at this year's San Diego Comic-Con -- Khaos Reigns! The cleric of chaos Havik has come from another reality to burn everything down, but he isn't alone. Kombat Pack 2 brings twisted versions of klassic characters and a chaotic group of multimedia guest characters. Watch the trailer and see for yourself:

Animality finishing moves make a comeback with the new downloadable content. A free update for all players to coincide with the September 24th release of the Khaos Reigns Bundle, which includes Kombat Pack 2 and the immediate release of new playable versions of alternate reality Sektor & Cyrax, and the shadow wraith Noob Saibot. You can see them all fighting furiously as part of the chaotic reality-bending story in the trailer.

For a more traditional flavor, there will also be pre-order bonuses: Ultimate Mortal Kombat 3 inspired palette swap skins for Sub-Zero and Noob Saibot, a new Empress skin for Mileena, and Wedding Scorpion. The Khaos Reigns Bundle will also include all Kombat Pack content - if you've been holding out.

While the three MK characters will be there to play as soon as the Khaos Reigns DLC drops -- you'll have to wait a little longer for guest characters: Ghostface of the Scream film franchise, Conan the Barbarian with the likeness of Arnold Schwarzenegger, and the Terminator sequel's liquid metal machine T-1000 portrayed by Robert Patrick.
