The automap display takes advantage of the rotating and scaling abilities of the Super FX 2 chip, with the entire map spinning around the player's position rather than the player being portrayed with an arrow. Due to hardware limitations, no particles such as blood impacts, smoke, or bullet sparks are present. The chaingun is capable of single fire (although emptying one bullet still produces a doubled sound effect). Moreover, the shotgun does not fire seven individual shots as it does in the PC version, but rather functions like a hunting rifle. This allows the player to shoot (and be shot) from a distance using the shotgun with no decrease in power. This version of Doom features support for the SNES Mouse peripheral.
