Amnesia Scares!

[Googolplex]

Yes, Amnesia is scary as hell.
I find Penumbra Black Plague was a bit scarier, but it's same FG universe, so you can fusion Amnesia & Penumbra to one game. They are common each other I think.

First time I played Amnesia, I thought it was a little too much of horror. The feelings of fear are not normal in this game. It is the highest measure of horror what you can imagine.

Hope they beat their own goals with the pig machine.
