Emergency Escape Tunnels

Ellmore Tuberculosis Hospital closed in 2003 after numerous rumors were swirling in the local community about illegal human experimention happening on the grounds unbeknownst to the government and has been left to rot since. Out of sheer human curiosity, you and a group of friends decided to see if the rumors were true. The five of you discovered a hatch behind the hospital which led to a series of underground Emergency Escape Tunnels, fairly pristine compared to the rest of the Hospital. After some exploration in the tunnels you've all found yourself lost. Your only goal is to escape.
