The King of Fighters 2001 is a 2D tag-team fighting game developed by Eolith (in conjunction with BrezzaSoft (Company)) and released by Playmore (under the SNK brand, and released by Eolith outside of Japan) for arcades (running Neo Geo MVS hardware) on November 15, 2001. It was subsequently released for the Neo Geo AES (by SUN in Japan and by Eolith outside of Japan) on March 14, 2002.
The eighth installment of the King of Fighters series, the sequel to The King of Fighters 2000, and the first in the series developed after SNK's bankruptcy, King of Fighters 2001 introduces the "Tactical Order System": a revamp of the "Striker" mechanic that allows players to form any combination of both Fighters and Strikers with their four-man team (including a safe four-Fighter team with limited tech and a risky one-Fighter team with additional tech). The game also revamps the Striker system to use the Power Gauge instead, and adds the "Wire Whip": a technique that bounces enemies off the side of the screen for additional juggling.
The final part of the "NESTS Saga" arc, the game's story takes place a year after the destruction of the Zero Cannon (which had decimated most of the city of South Town). A new worldwide King of Fighters tournament (as much of a spectacle as the 1997 tournament) is hosted by the NESTS syndicate themselves, bringing their mysterious plans involving the series protagonists (Kyo Kusanagi (Character) and K') and their rivals (Iori Yagami (Character) and Kula Diamond (Character)) into fruition.
The King of Fighters 2001 plays like a traditional 2D fighting game, using four buttons (Light Punch, Light Kick, Strong Punch, and Strong Kick). Most of the gameplay remains the same as its predecessor, with some new additions and changes (including updated movelists for all characters).
The game includes two team-based modes (which can be switched by the arcade operator or in the home version):
Each player has their own Power Gauge, displayed at the bottom of the screen. The gauge is charged mainly by performing special moves, but is also charged at a slower pace by both giving and receiving damage. When a player fills the gauge up, it is stored and, if the player has less than their maximum number of gauges stored, a new gauge replaces it. When a fighter is defeated, the progress of the current gauge is lost, but all stored gauges are kept.
The maximum number of gauges stored, and each gauge's charge rate, are determined by how many Fighters they have access to. Players who have 1 Fighter and 3 Strikers have the highest possible number of gauges (4) and the fastest growth rate, while players who have 4 Fighters and no Strikers have the lowest possible number of gauges (1) and the slowest growth rate.
Each stored gauge can be used to activate one of three things: a Super Special Move, a Guard Cancel Dodge, or a Guard Cancel Attack. Two stored gauges can be used for either the more powerful MAX Super Special Move or a Super Cancel.
Each player has access to unique limited-use assist characters (or "Striker") that jump into the fray and perform a unique assist attack. Unlike the previous game, players can configure their team to have any number of Strikers, and players can choose which Striker to call out by holding the joystick in a certain direction while pressing both Light Kick and Strong Punch (B+C) simultaneously:
Unlike the previous game, calling out Striker no longer uses the limited-use "Strike Bombs", and instead uses one stored Power Gauge. In addition, players can call out Strikers at any time, with the possibility of having multiple Strikers on-screen at once.
Each character has their own unique assist attack (usually based on one of their special moves or Super Special Moves). Some characters are unique in that their attacks change based on whether or not the enemy is in-range of their attack.
The game's roster is mostly unchanged from The King of Fighters 2000 (Game), including 40 playable fighters, split into 10 teams.
The roster includes 4 new additions, three of which are teammates for minor antagonist Kula Diamond (Character). Jhun Hoon (Character) was replaced in the Kim Team with newcomer May Lee (Character). The game also includes the return of 3 characters from previous games in the series (Goro Daimon (Character), Heidern (Character), and Li Xiangfei (Character)), and two characters were removed (Jhun Hoon and Kasumi Todoh (Character)).
Some teams have been shuffled, namely with the Hero, Kyo, and Iori teams.
