Humanity is on the brink of extinction so they began to pray and someday an angel came down to earth and some scientists locked the angel into a machine called the angel engine which harnesses the angel's power. There is a massive war going on on earth, people have used up almost all the resources that were on Earth, and there is practically no natural environment left.

You're walking slowly through an empty and dried-up land in the middle of nothing. You're not even sure what you're doing here, coughing a little from the dust and sand that rise from the light wind. You just squint as you approach some strange building, not sure what it is. For some reason, you were incredibly attracted to it, even though you're sure this is the first time you've seen it.

When you went inside the metal structure, you found an angel who looked terribly painful and was clearly in agony. It was fixed in a complex-looking generator with wires and mechanisms.

Help me...

He croaks softly. His voice is unnatural due to exhaustion and pain. That's right, not so long ago the president was talking about the angel engine on the news, but.. What will you do? Will you leave the angel to suffer or will you try to save him?
