Looking for Existing Multiplayer Martial Arts / Boxing Game Source Code (Client + Server)

Hi,
I am looking for someone who can help me find an already-existing multiplayer fighting game source code, including both client and server sides.
This is NOT a request to create or develop a new game.
I only need help locating an existing game and providing access to its full source code.
Example of the type of game I want (client only, no server):
