10 Rarest Xbox Achievements

Rarity: 0.01%

Initially, getting The Final Chapter achievement seems easy, because it involves playing as Jason - and let's be honest, everyone enjoys getting to be a terrifying horror villain at least once in your life.

However, in order to get The Final Chapter, you need to play as Jason for a thousand multiplayer matches. A full, clean one thousand.

As guides explain, the absolute quickest this can be done is in around forty two hours, but this requires you to use a method known as double boxing, wherein you use another console to create a separate account you can use to artificially assist you.

If you decide against that, the amount of time it'll take you then doubles, leaves you at a clean eighty four hours for one achievement. It is at least one hundred points though, so it's not a total loss.

In order to get this particular prize, you either need to game the system, or to be almost worryingly invested in playing as a hulking masked serial killer. Either way, your commitment is still undeniably impressive.
