“As in the original, each exchange direction – up, down or left/right – bestows a specific bonus. A downward exchange will still instantly grant you one bar of hyper meter, and upward exchanges still tend to do higher damage. In Ultimate, however, a sideways exchange no longer bestows half a meter. Instead, it will actually remove one bar of meter from your opponent. The new system change will hopefully encourage players not to limit their strategies solely to safe combos. In other words, you could stick with the safe combos, or steal a hyper meter from, oh, say, Phoenix.” —
