Parcel Inspector Simulator is a first-person inspection sim set on the night shift of a transit post office in 1962. Every parcel that crosses the desk is weighed, X-rayed, checked under a UV lamp, listened to with a probe and looked up in the terminal, then stamped: approve, return to sender, hold, dispose or confiscate. Regulations change from night to night, wages pay for desk upgrades and for a brother's sanatorium bills, and a 20-night story campaign with seven endings follows a favour that somebody upstairs keeps asking for. After the campaign the shifts go on as endless nights with special conditions.
