The stealth action genre has long been an echo chamber unto itself. While many games have integrated its core ideas, its pure form hasn’t evolved much since Metal Gear 2 on the MSX. It’s a genre that many critics have argued relies too heavily on trial-and-error, exists as puzzle games in action-game skin. Mark of the Ninja shrugs these distinctions off while living inside them. It’s a smart title that promotes a different kind of stealth: action not patience; the hunter, not the prey.
