 Character appearances were improved to make their moves "more responsive" to the player's input. They also wanted to bring back several characters they felt were absent for too long — including Sindel, Nightwolf, Baraka, and Mileena — and an arena with several weapons which players could use to fight; however, it was remade to become the Liu Kang's Tomb arena. Characters' combos were redesigned to be distinctive so that they would be more important; as Boon noted, they were necessary for any move the player would use to inflict more damage on an opponent. The Midway staff focused on the designs and functions of the backgrounds, wanting to make them as influential to the outcome of the battle as the fighting between the characters.
