Secrets. Exploits. Hidden unlockables. For years, people everywhere have scoured their favorite games in search of whatever might be buried just off the beaten path. Even now, there are players dedicated to checking every inch of the map in Destiny, or every corner of the dungeons of World of Warcraft. Sometimes, they find things that nobody expected. And sometimes, it turns out that everyone was being misled by unfounded rumors that spread like wildfire without anyone actually having proof that what was being talked about was even real. And when that happens, we get some of the craziest legends of video games that a ridiculous number of people actually believed, even though they were never real in the first place. That’s right, every myth on this list is false, but for a while, there was a vast number of people who thought they were true.
10. The Secret Cow Level (Diablo)
The original Diablo takes place in the small village of Tristram, which contains a few buildings, a blacksmith, and an old church that ends up being a multi-level dungeon that leads to Hell itself. Also, there are a few cows scattered around for atmosphere. And because Blizzard loves including little details to amuse people, if you click on a cow, it will moo. Click on it enough, the moo can become slightly aggravated. From something as simple as this came one of the first Blizzard myths in a long history, the legend of the Secret Cow Level. It’s unclear how the myth began, but it became an accepted belief that somewhere in Tristram was a way to access some sort of hidden level, that could only be unlocked by clicking on the cows in some way. Blizzard, for their part, played along, repeatedly denying its existence in any and all of their games while continuing to reference the rumor at every turn (“There is no cow level” is both a Starcraft cheat and a loading screen tip in World of Warcraft). In Diablo II, the Secret Cow Level became reality, as a hidden level full of angry, polearm-wielding cows that could accessed by players who had completed the game.
