Amnesia: A Machine For Pigs Discussion Topic Part 1

[Lleviathyn]

Complete guess as to game's backstory: Following the death of his children, our heartbroken, unstable protagonist Mandus seeks a way to bring them back (as implied by the poem on the main site). In the course of his feverish studies into theories of the afterlife, he stumbles across a substance with otherworldly power: Vitae.

Realising just how much of the stuff is required to pull off the ability to raise the dead, he creates a vast facility for the torture of pigs and extraction of vitae, throwing up a public façade of a meat processing factory. It begins to dawn on him that this isn't enough however, so he begins abducting the 'pigs' of society - criminals, the homeless, orphans - and subjects them to the similar treatments Alexander inflicted on his prisoners. It's these poor, broken souls that stalk the corridors of the factory, driven insane by pain and degradation.

Oh, and he loses his memory somewhere along the line.

That sounds like it could actually be the story. Possibly, he took the Amnesia mixture after he found out the magnitude of what he was doing, like Daniel.
