The Waterfront

The Waterfront (WTRFRONT.WAD) is a level created by Scott F. Crank in May 1995. It is maybe the earliest level to deliberately exploit the ghost monster bug, which its text file calls the "arch-vile bug." The author provided an additional text file documenting how ghost monsters are created, and how they can be killed only by rockets (or infighting), with a demo illustrating the technique.

Secrets

 * 1) While on the ship, right where you find the yellow key, activate the controls.  The alleged smokestack will drop behind you like an elevator, revealing a backpack. (sector 60) Get the backpack before the smokestack reappears; press the inside of the smokestack to escape if it rises around you.
 * 2) At the east of the walkway around the blue key structure is a teleporter pad labeled as "out of order."  If you enter it, you will be killed by exploding barrels.  Instead, inside the blue key structure, run onto the platform in the center with the chaingun.  Then, as quickly as possible, jump out of the structure, enter the tunnel at the south, and run through the open doorway to the east before it closes.  Once you make it, destroy the barrels in the cage.  Return to the "out of order" teleporter and use it; you will be teleported into the now-safe cage, where you can obtain a megaarmor. (sector 178)
