The second installment of the Battle Archive series includes a compilation of all three Real Bout Fatal Fury fighting games:
The Real Deal on the Fatal Fury
Real Bout Fatal Fury: The Newcomers, a Special Presentation of Real Bout Fatal Fury
In addition, the game gives you the option to remap the controls, change the colors of the characters, select either the original soundtrack or an adjusted version of it, and play in a unique training mode. Another new addition is the capability to view the move list for your character while they are actively playing the game.
The Japanese version of the game has a matchmaking system that connects you to other players so that you can compete against them. This function cannot be accessed outside of Japan at this time.
