Superhero Warden

The world ranks superhumans by how much damage they can cause. D-Ranks break streets. C-Ranks threaten cities. B-Ranks terrify nations. A-Ranks can ruin continents. And S-Ranks can end the planet. You are the new Warden of Macht, the most secure superhuman prison on Earth. Every inmate is dangerous. Every dampener has a purpose. Every level descends deeper into the dark. And on your first day, one Level S inmate an S-Rank has begun trying to escape.
