Note: This procedure involves editing game files; create a backup copy of them before proceeding. Use a text editor to edit the "xplayersl1.upl" and "xplayersl2.upl" files in the "system" folder in the game directory. These are all of the characters that are available in the game. Find any character that has a Menu= section that is not Menu="" and change it to Menu="" or Menu="SP" (if you wanted to be able to play as them in single player). For example, Xan's Character reads Menu="XAN". If you changed this to Menu="SP" or Menu="" he will be unlocked. The three characters that are locked are Malcolm, ClanLord, and Xan.
