Game Information
You are Edward Wright, an investigator who's goal is to investigate the problems of a Sewer. There are rumors of several deaths to occur in this Sewer, and now there is a problem in the Sewer. But in the middle of the investigation a sudden blackout occurs and you are the only survivor who has been trapped in this sewer. You only have whatever you have taken with you, and you can take stuff left out by the others. But the problem is, with such a horrible outbreak, can you escape the Sewer? Can you escape whatever is lurking in it? Can you trust everyone in the sewer? It all depends on you. Because nowhere is safe, your only hope is to run, hide or die.
