10 Brutally Hard Areas Hidden In Video Games

Though Playdead's gorgeous puzzle-platformer Limbo is a reasonably difficult game for the most part, it throws down one hell of a gauntlet to anyone who manages to unlock its bonus level.

Limbo's secret level is reached by first trampling the 10 eggs hidden deviously throughout the game, though mercifully that total can be racked up cumulatively across subsequent playthroughs.

You need to then head to the 26th chapter, where a previously locked door will now be open, allowing you to enter a secret pitch black level which makes Crash 3's faintly-lit UFO race seem positively acceptable by comparison.

The already dim environment is now bathed - nay, drowned - in darkness, making it incredibly difficult to traverse the level without dying repeatedly.

It's a deeply frustrating experience, lessened only by using headphones to guide yourself with sound cues, and the fact that the level at least contains checkpoints.
