10 Open World Locations You Shouldn't Enter

In a world filled with insane homicidal machine animals (machinimals? Machinimals.) it only makes sense that some areas of the map would be considered off-limits due to the abundance of said creatures. Enter the corrupted zones. 

There are 11 of these things out in the world, each one set at a certain level so you can't just do them all in one go. The level difference between each corrupted zone can be quite a leap, and the hardest one of them all is corrupted zone 11. 

Across the fandom, one type of machine is spoken of with fear: the Rockbreaker. A mechanical mix between a weasel and a shark, fighting just one of these things is a bad time, recommended only to those with high-level gear, a high vantage point, and at least a few explosive arrows. So of course, this zone throws TWO of the damn things at you. 

Entering this zone with anything less than all three of the above-mentioned points is an almost guaranteed game over. Rockbreakers are some of the toughest fights in the entire game when you're just taking on one, having to fight two is an exercise in torture.
