Amnesia: A Machine For Pigs is a horror game from The Chinese Room and Frictional Games. It was originally released in 2013. Here is a description of the game from the GOG product page:
In 2010 Frictional Games terrified the world with the cult horror Amnesia: A Dark Descent. Now they bring you a new nightmare. Created in collaboration with The Chinese Room, the studio behind Dear Esther, Amnesia: A Machine for Pigs is an intense and terrifying journey into the heart of darkness that lurks within us all.
Wealthy industrialist Oswald Mandus awakes in his bed, wracked with fever and haunted by dreams of a dark and hellish engine. Tortured by visions of a disastrous expedition to Mexico, broken on the failing dreams of an industrial utopia, wracked with guilt and tropical disease, he wakes into a nightmare. The house is silent, the ground beneath him shaking at the will of some infernal machine: all he knows is that his children are in grave peril, and it is up to him to save them.
The game giveaway ends in three days, so you should claim it now if you are interested in getting it for free. You’ll need to agree to receive GOG marketing emails in order to claim the free game.
