The player must use Sierra Madre vending machines 50 times.
Grants 75 XP upon completion.
- Each use of a machine adds one point to the counter, regardless of how much the machine was used. For example, using a machine to make five chems would produce the same output if only used to create one food item. The same machine can be used multiple times.
- The counter will raise only if something has actually been "crafted," giving the machine packs of cigarettes or pre-War clothes doesn't count for the challenge.
- The challenge is not repeatable.
