Various unlockables for King Of Fighters Evolution

The two cheapest (most effective) Strikers available are Dark Billy Kane and Dark Yamazaki. These two Strikers jump straight to your opponent, attacking in the air, then post them up in the air to attack. Billy Kane will post the enemy higher than Yamazaki, but may do more damage. Yamazaki will not only post the character up, but will toss him in the air slightly when he is through. With either type, have your character pull off some devastating Super Moves.

Two bonus strikers, Syo and Gai, will be unlocked at the Extra Strikers menu after fifty hours of game play are accumulated.

At the main menu, select either "Team Play" or "Team Vs". mode. Then, at the character selection screen, choose Krizalio, Ryo, and Iori as your players. Next, choose Takuma, Billy Kane, Yamazaki, or Alfred as your striker. Note: When you select Takuma as a striker, he will be Mr. Karate. In order to use Billy Kane, Yamazaki, or Alfred as your striker, you must unlock them first.
