It does. Though with online, the servers are split up between manual aiming and auto aim, so if your friends all play auto aim, you will iether have to use auto aimt to play with them, or stay in your manual aim server all alone. :/
Good to know. I always hated how aiming worked in GTA VC or SA. It's why I always just spawned a car and flew it into my enemies or something like that. Flying car cheat. Best thing in SA.
