This news post is a little late but I thought you should all know that the SA-MP
team have stopped development of a San Andreas multiplayer mod and have handed it over to Spookie to basically re-make it.
However, they did release an update to their Vice City multiplayer mod, and also, one to play the Liberty City total conversion mod online which is a great feature.
Download VCMP 0.1d
to play Vice City online, or LCMP 0.1d
to play the Liberty City total conversion for Vice City online.
It's recommended if you're using an older version that you update it to this latest version.
