10 Most Challenging Locations in Open World Games

OKB-ZERO (METAL GEAR SOLID 5: THE PHANTOM PAIN)

There’s no shortage of Metal Gear fans out there who aren’t the biggest fans of the open world approach taken by The Phantom Pain. If you’re in the group, OKB-Zero is probably one of your favourite areas in the entire game. And why shouldn’t it be? The tightly designed and meticulously crafted stealth gauntlets that the series has always been known for serve as the template for OKB-Zero, a vast location full of indoor and outdoor environments, multiple paths and shortcuts, and threats aplenty, from walkers and enemy soldiers to so much more. Getting through the area is no easy task, but boy is it incredibly rewarding.
