When entering multi-player mode, you do not get to choose which character(s) you would like to fight as. Instead, the Matrix selects two pre-set opponents depending on which scenario/background you choose. Note: Much like Morpheus vs. Neo in The Matrix, multi-player mode is essentially a training ground to hone your standard skills. Focus is unavailable for use in the Multiplayer program. You must have two Dual Shock 2 controllers, as the original Dual Shock analog controller does not work. There is no background music to accompany these battles. Below is the list of backgrounds/environments that are used in the single player game itself, and the characters the CPU will select upon choosing a certain background:

The Pit - Player 1: Seraph, Player 2: Ballard
The Ballroom - Player 1: Niobe, Player 2: Ghost
The Bedroom - Player 1: Cujo, Player 2: Vlad
The Atrium - Player 1: Sewing Woman, Player 2: Janitor
The Alley - Player 1: Firebird Man, Player 2: Police Car Man
