Which code could players enter during The End's blackout to play a minigame?

The code players could enter during The End’s blackout to play a minigame was the Konami code.

After the October 2019 event, Fortnite displayed a black hole instead of its usual game interface. Entering the famous sequence—up, up, down, down, left, right, left, right, then the action buttons—activated a small Durr Burger-themed shooter. Players could move around the screen and destroy falling objects, turning the otherwise silent waiting period into a hidden Easter egg.

The code originated in Konami’s Gradius for the Nintendo Entertainment System in 1986. Programmer Kazuhisa Hashimoto created it as a testing aid, and it became widely known after appearing in Contra, where it granted extra lives. Its use in Fortnite was an intentional reference rather than a gameplay cheat that affected Battle Royale matches.

The End and its blackout are sometimes remembered only as a cinematic transition, but the minigame gave attentive players something interactive to discover while Chapter 2 was being prepared.
