The King of Fighters 2001[b] is a fighting game produced by Eolith for the Neo Geo. It is the eighth game in The King of Fighters series, the third and final part of the “NESTS Chronicles” story arc, and the first game produced following the closure of the original SNK. The game was produced by the South Korea-based company Eolith and developed by Eolith and BrezzaSoft, a company formed by former SNK employees. The game was ported to the Sega Dreamcast in Japan only and PlayStation 2.
characters is an important decision
Selecting the proper lineup of characters is an important decision — as the more fighters you’re using, the smaller your Power Stock will be. The smaller the Power Stock, the fewer times you can use a striker and the less you’ll be able to perform guard cancels and other special moves. On the flipside, selecting a bunch of strikers with fewer fighters increases the power of your characters considerably; and not only will your defensive abilities and strikers be more effective, but you’ll have an increased chance to perform special maneuvers too. It’s a fresh approach to an old series and one we appreciated quite considerably.The Walking Dead: The Final Season Switch NSP

Another big addition for KOF 2001 what’s known as the “Wire Damage” attack; which is separated into two different types: Critical Wire for offense and Counter Wire for defense. Pre-loaded into certain types of hits, the Wire Damage attack works like an explosion: knocking your opponent to the other side of the screen and bouncing them back towards the user: which then opens them up for further attacks and combos. When used in conjunction with the new Super Attack move (which replaces the armor and cancel modes) the already faster King of Fighters 2001 turns out to be a quicker and enjoyable game than its predecessor.
Story of King of Fighters 2001
King of Fighters 2001 is a huge step forward in terms of gameplay and presentation when compared to that of 2000. Despite the fact that the fighting system itself is pretty similar, there are still a number of changes that have been made. The counter and armor modes, for instance, have been completely removed and Striker bombs have been eliminated in favor of power stocks. Also cool is that you’re no longer limited to participating in three-on-three battles, as now you can mix and match them any way you like. Player One, for example, can select one fighter and three strikers while Player Two can choose up to four fighters and no strikers.The Warlock of Firetop Mountain: Goblin Scourge Edition!

Any combination of this four-person team can be assembled or manipulated and those selections affect the defensive ability of your fighter, length of their power gauge, and how many Power Stocks they receives. Like in the previous game, the battles are once again between teams of four. Instead of a strict “three fighters and one striker” format, this installment introduces the Tactical Order System, which allows the player to select which characters will they control in combat and which characters will serve as strikers. Before each match, the player can form a team configuration of four fighters and no strikers, to one fighter and three strikers.
The visuals have been improved upon as well
offer players newly designed 3D polygonal versions of the stages that powered the arcade ROM. Should traditional SNK lovers prefer to play in the original sprite-based backgrounds, however, they can do that too; once they unlock them that is. Unfortunately, character sprites and super move animations are the same as they were in KOF 2000; with a few extra win poses and a couple of new frames of animation for astute observers. Bu the censors have found their way into this version of KOF as well, though with no blood or bounce anywhere to be found (with the exception of Heidern’s “Final Bringer” finisher).

In terms of its sound, 2001 doesn’t offer the arranged soundtrack that 2000 does (weird), nor is its soundtrack quite as strong. To its credit, though, developer Eolith has re-voiced certain characters like K’ and added a few bonus effects that the Neo version didn’t have, not to mention the fact that the 2001 intro is worlds better than the previous incarnation’s. We just wish there was an excuse to listen to Mad Fantasy or Rhythmic Hallucination again — which we haven’t been able to do since ’98.
