Reverse Engineering done on Game to get account name and pas

Need reverse engineering done on a game to get the account names and all char passwords of two accounts. It is a very simple game so should not be too hard. However you decide to do it is up to you. Once again need the account name and password and passwords of all chars for the accounts of two characters in the game. Basically what you will have to do is find out the two chars account names and password then get the password of all the chars on those accounts. There is an easy way of doing this but not sure how to go about it. I can explain more in PM.
