The game is played out in four cities: Miami, San Francisco, Los Angeles, and New York, each of which remain only partially faithful to the actual city layouts. A fifth bonus city, Newcastle Upon Tyne (where Reflections Interactive is based), is unlockable in the PC version through gameplay and in the PlayStation version using a cheat device,[7] but no missions are available and the playable area is small. The game was notable at the time of its original release insofar as the player was able to explore each city as an open world environment. Driver has often been compared to the Grand Theft Auto series. It also bears significant thematic resemblances to the 20th Century Fox movie The Driver (1978).
