Forum:I have a question: Face Down Attack Mode

Rules for Face Down Attack Mode
I found a card called "Darkness Approaches". It is a spell card with this effect: "Target 1 face up monster on the field; flipped it face-down but do not change its battle position" (effects are interpreted to Jan 2013 errata but not official). If the targeted monster is in Attack Mode, it will be Face-down Attack Mode but what does this mean compared to Face-Up Attack Mode?--Power32840 (talk • contribs) 20:05, January 10, 2013 (UTC)
