Chaingun (Spear of Destiny)
Chaingun is played when you pick machine gun in Spear of Destiny (DOS). In Wolfenstein 3D (DOS) you also could have machine gun, but while picking you heard synthesed sound effect, not the PCM one added in Wolfenstein's prequel.
Award Ceremony is track 38 in the game's data. Its title in the VOC meta data is "GETGATLINGSND". It was named after the gun unofficially, so game's developers should be contacted for proper name.
