Gameplay
As with most fighting games and indeed its predecessor, two characters square off with the goal of depleting the opponent's life bar. As with the original Killer Instinct, when a player's original life bar is fully depleted, he or she will fall to the ground, and immediately begin on his or her second lifebar.
As with the first game, KI2 relies on an automatic combo subsystem in its matches. The matches, as with Killer Instinct, revolve around a three strength system (Quick, Medium and Fierce). However, normal moves have lost a lot of their priority and range, as well as gaining extra recovery time. Throws have been added into the game to deal with blocking characters (as opposed to the top attack in Killer Instinct). Additionally, characters can be knocked down much easier with normal moves than in the first game, ending the possibility of opening with a 'glitch' combo and also weakening the effectiveness of normal moves. Normal special moves no longer are judged on priority, but instead follow a three tiered 'rock, paper, scissors' system, in which a certain special move will always break another certain special move (similar to the three tiered system in Soul Calibur). The system has been seen as flawed due to little differences between the special moves themselves.
Additionally, a Super bar has been added to the game (similar to Street Fighter Alpha or the The King of Fighters series). This super bar fills as players take damage. After the bar reaches a certain point, the player can use a multi-hit Super Move which is usually an extended version of a normal special move.
The combo system has its roots in the original Killer Instinct. By pressing a certain strength button after an opener move, a player will launch an auto-double and initiate the combo system of the game. However, unlike the first game, players can now open up combos with new and much less risky moves than before (most notable a close Fierce punch or close Fierce kick). Additionally, Super Moves can be placed into combos, greatly increasing their damage and potency as well as being unbreakable. Additionally combos can be extended using throws, super linkers, manual-doubles, and super end specials. As a result of the weakened normal moves and other changes to the system, combos have now become more devastating in KI2. In an apparent effort to help ease this dominance, combo breakers are now easier to perform. Unlike combo breakers in the first game, which also required a three tiered 'rock, paper, scissors' system based on strength to break, combos are now broken depending on the type of attack. Punches break kick doubles, and kicks will break punch doubles.
Parry, an advanced new addition, allow an open counter-attack after a successful parry block. A player can assume a standing defensive position and cause the attacker to temporarily freeze if the parry is successful, and from there either perform a special stunning technique or a 3-hit variant of a Special Move.
The finishing moves have also been reworked. Now each character can only execute these attacks when the opponent's second life bar flashes red (unlike the first Killer Instinct the opponents falls when he or she loses all of his or her energy bars). Each characters has two Ultimate combo moves (one of them can be executed without executing a combo), the Humiliation sequences were dropped, and the Ultra combo feature is still intact. Unlike the Mortal Kombat fatalities, however, the KI2's finishing moves do not feature brutality or dismemberment. Here's how to earn each victory: The supreme victory is earned by winning a round without losing the first bar on the player. The awesome victory is earned by performing finishing moves and the ultra victory is earned by performing the ultra combos.
