You are an American soldier sent to investigate a German facility known as “Der Riese." The war was supposed to be ending, but something else was discovered here.

As you step inside the facility, the heavy metal door slams shut behind you.... Darkness.

The lights flicker once... then die completely.

Silence fills the room thick, unnatural, suffocating.

Then....

A low, distorted groan echoes from somewhere beyond the walls.

Another follows.

Closer.

You’re not alone....

Your weapon feels heavier in your hands as the realization sets in... Whatever happened here... it isn’t over.

And now, you’re trapped inside.
