Essentially, Mortal Kombat II is an extension of the game system of Mortal Kombat. A few normal moves have been added (close high punch and crouching punch, for example). Additionally returning characters gained new special moves. The game also introduced multiple fatalities, as well as additional finishing moves to the franchise. However, each character still shared generic attributesspeed, power, jump height and airtimeand all normal moves were similar between each character. As with its predecessor, the only thing differentiating each character were their appearance, special moves, hit detection, and finishing moves. This has also led to the similar criticism of the fighting system being very shallow and lacking any real character depth. However, it should be noted that the game plays slightly faster and much more smoothly than the original.
As with its predecessor, matches in the game are divided into rounds. The first player to win two rounds, by fully depleting his/her opponent's life bar is the victor. At this point the loser's character will become dazed and the victor is given the option of using a finishing move. In addition to the fatalities of its predecessor, the victor could also use babalities, friendships, and stage specific fatalities.
This game also drops the point system of its predecessor, in favor of a win tally.
The characters of Mortal Kombat II have a less digitized and more hand-drawn look to them than in the first game. Both the theme and art style of the game are slightly darker, with a less vibrant color palette employed. Mortal Kombat II also strays from the severe oriental theme of its predecessor, though it does retain the original motif in some aspects, as in some of the music. Finally, the nature of the game is slightly less serious with the addition of trivial and 'joke' fatalities and the addition of the alternative finishing moves.
Following his defeat, Shang Tsung begs his master, Shao Kahn, to spare his life. He tells Shao Kahn that the invitation for Mortal Kombat cannot be turned down, and if they hold it in Outworld, the Earthrealm warriors must attend. Kahn agrees to this plan, and restores Tsung's youth. He extends the invitation to Raiden, who gathers his warriors and takes them into Outworld. The tournament is dangerous, as Shao Kahn has the home field advantage, and an Outworld victory will unbalance the furies and allow Outworld to subsume Earthrealm. (Wikipedia)
