Adaptive difficulty from MGSV. The game doesn't have a difficulty setting. Instead, it adapts to your playstyle to change the way you play. So if you rely on headshots too much, enemies would proceed to wear helmets. You kidnap too many people? Then the enemies plant fake balloon sized humans to distract you. I'd say though that the execution could've been more refined and would've wished for other games to have been inspired by this system.
