NBA Jam · Sega Genesis / SNES · 1993 · Hidden Feature
Effect: Sets the player's character 'on fire' — boosting speed, jumping, and shooting accuracy dramatically, and making them temporarily unguardable.
NBA Jam's "on fire" mechanic was not a traditional cheat code but a hidden in-game trigger that became the game's defining feature. After hitting three unanswered baskets, an announcer would shout "He's heating up!" and then "He's on fire!" as the player burst into flames. The effect gave such a massive advantage that matches could turn completely on a single hot streak, making clutch comebacks and blowouts both equally dramatic. The phrase "He's on fire!" became one of the most parodied and quoted lines from any video game of the 1990s and remains instantly recognisable decades later.
