E1M4: Command Control (Doom)

E1M4: Command Control is the fourth map of Knee-Deep in the Dead in Doom.

Development changes


E1M4, started by Tom Hall and finished by John Romero, can be found in primitive versions in the 0.4 and 0.5 alpha versions of Doom, both as E1M7.

The version of E1M4 in Doom 1.0 contained a structure formed as a swastika (visible in the upper-left center of the 1.0 map to the right), inserted as homage to Wolfenstein 3D. The symbol was changed to a shape that only loosely resembles a swastika for version 1.4, as John Romero has commented :


 * "Yes, [in Commander Keen 5] there is a swastika in one of the levels, one of my levels to be exact, but I removed it shortly after the game was released because people were upset that an evil symbol was in a cute kid's game (the changed version is in the screenshot). It was a premonition of things to come, namely, Wolfenstein 3D. I also put a swastika in Doom ' s E1M4 as a Wolf3D reference, but I changed it later for the exact same reason."
