The People of Babylon pulling a Big Damn Heroes moment for the Prince after he saved them earlier and holding off the Vizier's army so the Prince can slip by and kill the Vizier once and for all.
The Prince managing to kill the Vizier, now Zurvan the Physical God, after much struggle and saving his kingdom.
The Prince managing to overcome the malicious Dark Princetwice after being harangued and insulted by him throughout the game. Once through sheer force of will, and again by admitting his faults and simply walking away.
The speed kills are overall some of the most satisfying combat portions of the game. Using quick reaction, the Prince can butcher enemies in seconds with flashy choreographed moves. Works best especially with enemies that require multiple hits.
