Critical Blow is a fighting game developed by Racjin and published by Banpresto for the PlayStation. It is the sequel to another PS1 fighting game called Genei Tougi: Shadow Struggle.
Critical Blow is a one-on-one, 2D-style fighting game that features polygonal characters. It uses four buttons overall, but one is primarily for the game's trading card system, which doesn't apply to many of the game's stock characters. The game has one punch button, one kick, and an action button that combines with the attack buttons for throws and is also used for evasive rolls.
The game has a card earning and trading mode that lets you fight against AI opponents to earn cards and experience that are used to make the fighters more powerful. You can also use cards to apply elemental effects to special attacks. Card-edited fighters can be saved to memory cards and used in the game's versus mode.
