What are the three attack combos for Infinity Blade?
Huge: Up Down Up
Mega: Up Up Down Down
Ultra: Up Down Left Right Up
For the highest # of XP for the combo after you kill an enemy, do Up/Down/Up,Up/Down/Left/Right/Up for a 3x then 5x combo. You need perfect timing to do a 5x combo twice, and if you fail, you will only get the first 5x combo with only a few points for no second combo.
