‘''My original sketch for E1M1, the first map in Quake. This was on my pad of paper where I listed myself as Project Specialist because I did so many different things on our games. The original filename of E1M1 was jrbase1. This map is for the inside of the base. Other sketches cover the outside area.''’ — John Romero.
