10 Most Twisted Video Game Achievements Ever

The first title spawned from the purchase of the series by Bethesda, Fallout 3 saw the post-apocalyptic game series triumphantly transition from an isometric role-playing game to one of the best action RPG series of the 2000s.

The game also came with five separate DLC expansions, that allowed the Lone Wanderer to embark on a whole new batch of adventures away from the Capital Wasteland.

Though none of the other DLC packs was quite as distinct as Mothership Zeta, which saw the player character abducted by aliens and forced to fight their way off the ship in order to return home.

Making your way through the ship to safety is a relatively easy task, especially if the player already has a decent array of weaponry built up.

However, what makes the Alien Archivist achievement so difficult to obtain is that certain areas of the ship cannot be returned to, meaning that if the player hadn't picked up the captive recordings on their way through the linear experience they'd better hope they had a previous save to revert to.
