restrictions, the actors' costumes had to be simple and no acrobatic moves such as backflips could have been recorded; the most difficult moves to perform were some of the jumping kicks. Several characters (namely Jade, Kitana, Mileena, Noob Saibot, Reptile, Scorpion, Smoke, and Sub-Zero) were created using the first game's palette swap technique on just two base models. The game was noted for its "strong female presence", as it was featuring more than one woman character as it was common in the genre at the time. Due to memory limitations and the development team's desire to introduce more new characters, two fighters from the original Mortal Kombat, Sonya Blade and Kano, whom Boon cited as the least-picked characters in the game, were excluded, substituted by two palette swaps, Mileena and Reptile. In place of Sonya, two new playable female characters, Kitana and Mileena, were introduced so the game might better compete against Capcom's Street Fighter II: The World Warrior featuring Chun-Li.The One Amiga 75 (December 1994). Another planned female fighter, based on the real-life kickboxer Kathy Long whom Tobias admired, was omitted due to time constraints. A male bonus character played by Kyu Hwang was also cut from the game.VideoGames 63 (April 1994). Release The first version of MKII, revision 1.4, "was effectively a public beta test", featuring few Fatalities and many software bugs; it also lacked the endings for the characters. It took three subsequent revisions to have the moves and finishing moves finalized and all the bugs corrected, also adding additional content, as development had still been in progress for all that time. The final version was revision 3.1, released in January 1994. Marketing and merchandise In conjunction with the release of the arcade game in 1993, an official comic book, Mortal Kombat II Collector's Edition, written and illustrated by Tobias, was released through mail order, describing the backstory of the game in greater detail. Acclaim Entertainment stated that it "had started Mortal Kombat II with a $10 million global marketing campaign" for the home versions. A part of this sum was used to film and air the live-action TV commercial created by David Anderson and Bob Keen. The video featured Scorpion, Sub-Zero, Reptile (with a notably more reptilian appearance), Kitana, Baraka and Shao Kahn, who were played by the same actors as in the game. The game's promotional campaign's tagline was "Nothing ... Nothing can prepare you."
