Advertised with "low tar" and "genuine taste," Pyramid cigarettes were produced before the Great War. While they can't be found as a miscellaneous item in the world, they are popular among members of the New California Republic Army, as most soldiers keep a packet in the goggle strap of their helmets.
The Pyramid pack used on the helmet is a combination of two cigarette packs. The basis is a 1950s Camel design, which provides the supporting columns, background, and palms. The camel was not completely removed by the texture artists, as its two front legs, arranged exactly like those of the animal on Camel cigarette packs, remain. The animal itself is replaced by a single golden pyramid (similarly to real-world Pyramid) with the brand name and product description replaced by Pyramid (half not visible, due to the torn-open pack) and Genuine Quality Low Tar respectively.
