Tech Gone Bad or E1M8b is a single-level PWAD for Doom designed by John Romero. Released on January 15, 2016, it is the first level created by Romero in over 21 years; it is also his first non-commercial map. It occupies the E1M8 slot and contains 232 monsters and 10 secrets.


After exiting the Computer Station you knew the worst was up ahead. You still hadn't reached the place where the demons were coming from. The steel door shuts behind you as you realize you're there; you're at the Phobos Anomaly. Cracks from hell are all over the place as seepage from the portal invades the entire installation. Now it's time to find the portal and stop the demons from coming through. You know UAC had hundreds of scientists working at a high-tech lab somewhere in this area, and the portal must be connected to it somehow. Time to lock and load.
