10 Video Game Difficulty Modes You Must Complete Without Dying Once

10. One Life - The Whole Game

Starting off the list, we have One Life; product of Steam user "Kefir!". Like many titles released on Steam Greenlight, its production values and overall competence are rather low, but it distinguishes itself through one key difference. It was released in 2015 alongside countless other small titles.

It takes the survival genre very literally, planting players in online matches with just one life to live. The obscure indie title locks you out of the game forever if you die just once. This could be other players, the infected or other environmental hazards. Think DayZ but you're not allowed to play again on death.

Perma-perma death is a tough proposition when you're asked to pay money to play it. One Life charged players $10 to give it a go; it's a low price, but all too easy to throw away. Ideally, One Life dramatically ups the tension of play, but due to its place as an indie title it's makes the least impact of the ten games.

With Steam Greenlight having closed and replaced by Steam Direct, the game will soon be unavailable for purchase. Still, for what it was, One Life was mildly innovative, though its central idea hasn't been adopted by any other companies.
