How do you get 2 player gta san andreas?

How Do You get 2 player on grand theft auto san andreas??? I've read the things u've all said but none of it is there. And I must not be that far into the game because I don't have a girlfriend yet. How do you get one? Please help.

Well.. You need to be into the secound city. And find the two player icon... Its easiest in the third city however cause you pass two of them on a mission

Thanks! I found that quite helpful actually. Although I only have the first island and part of the second, I found a cheat to unlock the whole map. However, that won't unlock all of the missions aswell, so where on the third map may this mission be located and where specifically are the icons. I'm that retarded I've read over 100 comments on this question and still can't find an icon. haha. anyway thanks.

I dont know how I want to know how so me and my friend can both play!
