MTAVC have released version 0.4 of their multiplayer GTA mod. It is now for both GTA3 and VC and is just over 1mb. You can download it off their site but you may have to wait in a queue so I added it to our database where there are no queues.
I also made a category for previous version of MTA which is here.
I have also added loads more downloads so check them all out.
