- Combat rifle can be found on the roof of the Super-Duper Mart. The rifle is laying on the bed on top of the roof.
- Power armor chassis can be found behind the Red Rocket, usually in the power armor station.
- Vault-Tec bobblehead under the bed on the roof of the Super-Duper Mart.
- Magazine against the northeast wall, beside the serving counter in the Super-Duper Mart.
