There’s a wildly obscure easter egg in Lego Batman, I’m surprised anyone found it: it’s hidden in BASIC code for the Commodore 64
An obscure easter egg has been discovered hidden deep within Lego Batman that contains functional Commodore 64 BASIC code. The easter egg was uncovered by TikTok user Cabelsa and appears in a computer boot-up splash screen that displays when Batman analyzes or interacts with a computer terminal in-game. Rather than being purely decorative window dressing, the splash screen contains actual Commodore 64 BASIC programming code, representing one of the game’s most niche and technically obscure references.
The discovery exemplifies the meticulous level of detail that developers often embed into Lego games, which are renowned for their extensive catalogue of pop culture references and easter eggs spanning decades of geek culture and gaming history. Finding this particular easter egg required not only spotting the flash of the splash screen during regular gameplay but possessing the technical knowledge to recognize Commodore 64 BASIC code—a skill that most modern gamers would lack without specific familiarity with the legendary 1982 computer system and its programming language.
