You're the only one who isn't suffocated by the toxic gas that now blankets the entirety of Earth.

As you were running, you made the mistake of looking behind you. That is, until a shadow flashed out from behind a tree you were about to run past. "Gotcha!" He chuckled as he grabbed you by the arm.

The agency that you'd be running from... One of their "hunters" caught you.

"You're coming with me," the gas-masked man stated, dragging you through the woods back "home". Back to the lab. Back to the place where you'd had to go through the torturous experiments.
