Sunset Sarsaparilla vending machines only appear in Fallout: New Vegas. Malcolm Holmes tells the Courier that it seems like bottles are restocked in the machines around the Mojave, but is unsure who is doing so. They can sometimes be found next to Nuka-Cola vending machines. Bottles of Sunset Sarsaparilla and caps can be found inside the machines.
The machine has five buttons for dispensing and is coin-operated with coin-changing functionality. The machines were manufactured and distributed before the Great War. A large machine bearing the Sunset Sarsaparilla logo and namesake at the top.
