Inspiration and development

The map was called "Buckshot" due to the gimmick of the player only having access to the shotgun and super shotgun throughout the level's duration. While it is possible to carry other weapons into this level during continuous play, if the player chooses the third episode in the New Game menu or pistol starts the map, aside from the 50 bullets that the player starts and what other bullets can be gleaned from ammo backpack pickups, the player will only have access to shells.
