A particular weapon in game play is the "nailgun" which can be reloaded by collecting ammo boxes decorated with the [[Logo History|NIN logo]]. Also Reznor was asked by id Software to score ''Quake II'' and ''Quake III'', Reznor but declined due to the style of music they were looking for.[http://www.nin-pages.de/2000_Incite_Juli_english.htm] He was also the original choice for sound design on id Software's ''Doom 3'', but circumstances halted his involvement. Former NIN member Chris Vrenna composed the game's theme song.
The game's readme mentions something called [[Nothing Interactive]], an entity that has never been referred to on any other NIN or [[Nothing Records]] product.
