Congratulations, you have completed the game. Now you are asking for easter eggs, hidden maps and how to unlock the next difficulty level. My advice as someone in a similar life phase is to play something different. I understand you want money but all that chatter about roles, levels,... It bores me to death, which by the way is not that far. Pick something you actually like because most probably you are not going to get much further.
