Version 0.3 of GTA3MTA, the multiplayer mod for Grand Theft Auto 3 has been released:

    Features of MTA v0.3b:

    - see each other walking

    - see each other shooting

    - see each other driving

    - gamemode DM-gangs supported for now

    - 6-12 players recommended for internet play

    - GTA3:MTA servers visible in ASE (The All-Seeing Eye)

    MTA v0.3b is optimized for GTA3 v1.1, and is not tested well with v1.0. So we recommend you to use GTA v1.1, although we made it possible to change the GTA3 version in MTA v0.3b.
