I'm playing sanandreas on ps2...
My last mission was 'New model army'... after that... no mission is coming...
WAT TO DO?? Plzz tell me!

Have you tried restarting the PS2 or even leaving it for a day to cool down and trying again? Also, have you ever had an issue with the console/ other games when using this console before? I used to have an original PS2 and I had to have it cleaned once as it started acting up and freezing on occasion... perhaps it can be that simple for you too. I would need a little more info if you have it, then we could see what other steps to try.
