Lock - Games

In game design, 'Lock' represents a fundamental progression mechanic. It manifests as literal locks requiring keys or puzzles, metaphorical locks like skill gates or narrative barriers, and systemic locks such as level caps or resource requirements. This concept creates tension, rewards exploration, and structures player experience. Well-designed locks feel earned when overcome; poorly implemented ones frustrate. From Zelda's dungeon items to Metroid's ability gates, locks shape pacing and mastery. They transform environments from static spaces into interactive puzzles, making the player's journey one of constant problem-solving and discovery.
