Midnight Madness is a complete rule set for Castle Panic. It allows monster tokens to be placed and moved FACE DOWN adding an extra panicky element of surprise to the game. It plays as Solo, Standard, or Co-op with a Normal, Challenging, and Uber difficulty option. Colored text indicates special difficulty rules. FACE UP and FACE DOWN in caps indicate where the rules differ from the original. Version 1.3 of the the Rules changes some text for better clarity and adds some minor corrections.
