Ken’s Labyrinth is a first-person shooter DOS game, released in 1993 by Epic Megagames (now called Epic Games). It was mostly coded by Ken Silverman. Ken’s Labyrinth is graphically similar to id Software’s Wolfenstein 3D in that the levels were designed using a grid-based plane, resulting in perpendicular walls and textureless floors and ceilings. Arguably its most astounding feature was the existence of interactive sprites and textures, like slot machines.
