Shows a path for reaching all score-affecting secret areas in PC Doom II level 20, Gotcha! Enable Captions to see when Secrets are scored. This video replaces an older one (youtu.be/h-wKBMz5wro ) that did not show how to reach the exit.

See classicdoom.com/maps/d2secs/20-z.htm for a map of the Secrets.

Note: There's also a well-hidden alcove with a BFG 9000 and cell ammo, but neither the ordnance nor the space they occupy affect the Secrets-found score, so they're not shown here. For a video showing that area, see youtu.be/Mg-dQZy8aUA
