1. Overview of Totally Reliable Delivery Service Totally Reliable Delivery Service is a chaotic physics-based delivery simulation game developed by We’re Five Games and published by tinyBuild. Released in April 2020 for PC, Nintendo Switch, PlayStation 4, Xbox One, and mobile devices, the game challenges players to deliver packages across a whimsical, open-world cityscape. True to its name, the game’s mechanics are deliberately unreliable: characters flop, vehicles flip, and cargo flies away with the slightest miscalculation. Up to four players can cooperate locally or online, turning simple delivery jobs into slapstick disasters.
