 In version 1.4 for the PC, an alteration was present. In Episode 1, Map 4:  "Command Control", a structure originally lowers to the ground to create a  pattern of a swastika on the floor. This was done as a reference to  "Wolfenstein 3D" however, this offended many players so it was changed to a  different, yet similar structure in this version. (See links under  "photographs")
