THE KING OF FIGHTERS 2000

The objective of Party Mode is to defeat as many opponents as you can before you run out of health. There is also a five minute timer below your life bar, once it runs out, you will slowly begin to lose a small portion of your health over time until you have a small fraction of health left. Attacking your opponent with an attack or combos can help restore health in some increments and after every ten opponents you have defeated, you will gain an additional minute on the timer.

The requirements to unlock each maniac striker are as follows but after defeating the required amount of opponents, stop and have the opponent defeat you in order to unlock the one(s) whose requirements you have met and the trophies that correspond with the manic striker(s) you have unlocked, as they will have to be unlocked one by one in each run you do and not in one complete run.

• Heavy D!, Lucky Glauber and Brian Battler (Terry, Andy and Joe) - Defeat more than 14 opponents
• Orochi Iori and Orochi Leona (Benimaru and Ralf) - Defeat more than 27 opponents
• Mr. Big and Wolfgang Krauser (Mai and Takuma) - Defeat more than 36 opponents
• Heidern (Whip) - Defeat more than 40 opponents
• Orochi (Leona) - Defeat more than 70 opponents
• Krizalid (K') - Defeat more than 99 opponents

In addition, you can also unlock each of the aforementioned strikers above by clocking in a specific amount of hours in your play time as you play the game.

• Heavy D!, Lucky Glauber and Brian Battler - 5 hours
• Orochi Iori and Orochi Leona - 10 hours
• Mr. Big and Wolfgang Krauser - 15 hours
• Heidern - 20 hours
• Orochi - 30 hours
• Krizalid - 40 hours

I also highly recommend turning on auto save by going into "Options" -> "Save or Load" before attempting Party Mode and unlocking these trophies because once you turn off the game and lose your progress (depending on which trophy you want to aim for next) you will have to resort to playing through and defeating that set number of opponents again before starting the next party mode run to retain the progress you have lost. You can check how many hours of game time you have clocked in by selecting "Chart" in the options menu. In addition, there is also a faster method to unlocking each maniac striker in the game on Party Mode by using Chang Koehan and spamming his Hiki Nige attack () which will let him slide with his ball in front of him.
