on the ps2 version there where a few levels that got me stuck, firstly the one where you had to take guns from a train in los santos, rather early in the game. The next one i had problems with, i to this day have still not completed is the shooting the small heli's from the toy store roof, and finally the end mission, man thats LOOOOOOOONNNNNNNNNGGGGG if it where shorter it would be 10 times easier, but it aint, so..... erm..... i done it anyway
