Gradius – The Konami Code

Every game is created with a debug mode so the developers of the game can test it. This debug mode is a set of tools the developer can access when they’re playing an early version of the game. It’s usually disabled once the game is released. While working on Gradius, programmer Kazuhisa Hashimoto thought that the game was too hard so in order to debug the game he developed a cheat code which granted players full power ups however he forgot to remove it. As a result, players were able to input a series of button presses and access most of the power ups in the game.

No game is perfect, and since the time of Pong, bugs and glitches have been a huge part of video games. Some are funny and unpredictable. But every once in a while comes a glitch that is just scary and creepy. It’s happened to all of us. So we’ve compiled a list of the creepiest glitches that ever occurred in some of the most popular (and not so popular) games.
