Instructions
Kill innocent non-player characters in the neighborhood. Press "Down" to disable your safety and press "X" to swing your sword around. With the safety off, you will deal damage to any character your sword touches, hostile or otherwise. Murdering citizens will cause guards to attempt to arrest you and attack you if you refuse to pay the requested fee.
Make evil decisions when completing quests. "Fable II" does not deal in gray areas. For example, making evil decisions throughout the game will allow you to turn a man into a drunk, refuse to free slaves and select the "Sacrifice" option at the final quest.
Raise your stores' prices. Walk up to a store you own and press "Y" to modify the price. Raise it all the way up to "+100 percent," maxing out your corruption level and the amount of money you receive per day.
Cheat on your spouse. In the same way you courted your spouse, you can use the "Come Hither" expression on any qualifying person. An NPC that responds positively to your expression will follow you. Take them to a bed that you own to cheat with your follower.
Commit polygamy. Propose to any person with a heart over her head, indicating she is in love with you. Walk to any house you do not own and press "Y" to purchase it as a marital home. Every spouse you obtain while already married will further increase your corruption.
