Finally, in the fall of 2002, Midway released the next fighting installment for its Mortal Kombat franchise. It was the first Mortal Kombat fighting game to be released in five years. Mortal Kombat Gold was released in 1999 for the Sega Dreamcast, but it was simply an updated version of Mortal Kombat 4. Deadly Alliance brought life back to the series, which had been slowly declining during the late 1990's, due to some lackluster action/adventure titles and the leaving of Mortal Kombat co-creator, John Tobias.
Deadly Alliance featured a completely new fighting engine and control scheme. It possessed a feature which no other fighting game before it had - the ability to switch your kombatant's fighting style during gameplay. Each kombatant in Deadly Alliance had two hand-to-hand martial art styles and one weapon style, which could easily be toggled with the push of a button. This ability to switch allowed players to pull off huge string combos that spanned over each of their kombatant's styles.
Deadly Alliance was the first Mortal Kombat game to feature Konquest mode. Konquest mode was simply a glorified training mode, however, as you progressed through it, you were treated to an extensive amount of backstory about the kombatant you were using.
Deadly Alliance also changed the way secrets were unlocked. A new area, called The Krypt, was made up of a large grid of koffins that players could open using kurrency earned during arcade, versus, and Konquest modes. Rewards ranged from unlocking new characters and arenas to concept art and pictures of the MK team.
Another feature of Deadly Alliance which deserves mention was the inclusion of mini-games. Test Your Might had returned, along with a new game called Test Your Sight, where players needed to follow a group of cups as they randomly switched places with each other and choose which cup the Dragon Symbol was under.
