The Farm (2004)

From the introduction:

A Modest Proposal
The Farm is a horror roleplaying game about the lives and deaths of people trapped in a mysterious place called "the Farm." Players start the game knowing precious little of their environment or their fellow captives.

Over the course of the game, they’ll learn more about the dire situation in which they now find themselves. They’ll make hard choices, see horrific things and maybe, just maybe, they’ll make their escape.

Eventually, everyone leaves the Farm.

Survival of the Fittest
The Farm is a game about survival against all odds and at all costs. The player characters in this game are average human beings from all walks of life. The one thing they all share in common is that they have all been brought to a place called the Farm.
