Allen Marks

 was a Sunset Sarsaparilla star bottle cap hunter in Fallout: New Vegas.

Background
Allen Marks is apparently a murderer who chased and killed people in order to steal their Sunset Sarsaparilla star bottle caps and reclaim the legendary mysterious prize. By his location the player can tell that he gathered at least 50 Sunset Sarsaparilla star bottle caps as the player can find his body inside the Sunset Sarsaparilla Headquarters vault room where the prizes were. Ironically, his prize was nothing more than a Sunset Sarsaparilla Deputy Badge.

He is first mentioned by Malcolm Holmes, warning the player about his murderous attitude toward people with the star caps. The player can encounter this character's body during the quest A Valuable Lesson, whose title refers to the great crimes Allen Marks had committed in order to receive what proved to be not only a worthless prize but also a fitting end!

Allen Marks died after getting trapped inside the Sunset Sarsaparilla Headquarters storeroom. He most likely died of either asphyxiation, or a wound (that he got from fighting the robots in the building), or from drinking too much Sunset Sarsaparilla (as Festus mentions that drinking too much can cause several unwanted side effects, and thus explaining the stockpile of Caps). Before his death he recorded a holotape which can be found next to his body. He also possesses the unique laser pistol, Pew Pew. The laser pistol found on his body can be accessed just by looking over it and collecting it but you can't get it by looting his body.
