10 Video Game Difficulty Modes You Must Complete Without Dying Once

For over two decades, Hideo Kojima's Metal Gear was the reigning champion of the stealth genre. Through a combination of deep stories, versatile gameplay and committed technical presentation.

As the series grew and improved, new challenges in its gameplay opened up. Guards grew smarter, levels became more complex and the number of options available to Snake and other characters began to expand. It varies between releases, but it was arguably Metal Gear Solid 2 that had the strongest and most merciless foes, which emphasised the importance of remaining unseen.

That iconic alert sound was a sudden reminder that you had messed up and the task quickly shifted to escaping the enemy. For the hardcore crowd, Metal Gear has offered several incentives for those who adopt a true stealth playthrough. Unlockable items, better rankings and the thrill of slipping by undetected. Many skillful attempts have been uploaded to the web.

Then there's European Extreme for the true masters of the franchise. On the moment you trigger an alert in either Metal Gear Solid 2 or 3, the game immediately ends; there's no room for evasion here. To beat it, you'll need full knowledge of enemy behaviour and placement alongside advanced use of the game's mechanics.
