All Superheroes Must Die

Four superheroes find themselves abducted by their arch nemesis and are forced to compete in a series of challenges in order to save an abandoned town full of kidnapped innocent civilians. They go through round after round of violence and are unable to save any of the civilians as the challenges seem to be rigged in an effort to make them lose. The heroes discover that the arch nemesis is held up somewhere in the town and make a plan to find him. After a long night with many people both good and bad losing their lives, the heroes finally track down their arch nemesis and confront him in an attempt to save not only the innocent civilians and the town, but what's left of their own lives as well.
