Hey Papa, what's so hard with the bank heist, i did it without cheating and i'm sure most people made it without cheating as well. And I agree with M. Bull, cheating takes away all the fun of this game.
Yeah I managed it. Took a couple of attempts but got there without too much fuss. It's not impossible by any means. Also, as others stated, cheating does tend to take away much of the fun of the game, especially if cheats are used to further your progress. Cheating to help you finish a game just takes away any sense of achievement.
