That's right.

The mod you once loved 12+ years ago is making a come back.

Recently, I discovered that one of the old developers released the very dated source code, I forked it and began ripping it apart,

The original source code was built under a 32 bit system architecture so many things were outdated, on top of that Mafia II definition edition has been released 6+ years now.

I used todo testing only for this mod, wishing someday I could achieve modding the game myself and the time has come as I've brought on a lot of new programming and development skills since testing this project.

I will progressively post screenshots here and videos.

My goal is:
- Get syncing working again fully (raknet currently transmits player POS which is perfect for the clients)
- Bug handling
- Clean ass in-game menu
- DLC Interior unlocked, currently I have the vinci mansion and the land for joes adventures all accessible and unlocked in MP.

Hey Yall. It's been a long time and I don't know how many of you will check this but I am reviving M2 Multiplayer. I have the original source code and have begun rebooting things for Mafia II the definitive edition.

This will also include new features, a clean and easy to access menu and more. Working on it in my free time as I only used to be a tester for this mod back in the hay day, now I am developing it under Rak Net as it was done before. Big dubs to scripthook being made for DE as it's made a lot of this possible.
