Revolution 4 was a PlayStation 3 prototype, which was developed by Sony Cambridge in 2006. The central idea for this game was a first-person shooter set in the UK facing a War of the Worlds-style alien invasion. Soon after pitching this concept the team learn that Resistance: Fall of Man was in development at Sony America featuring an alien invasion of the UK in a first-person shooter.
The game would started with the player (playing an “everyman”-type of character) on their way to work in a busy London high-street as the invasion starts in King’s Cross. The player would have to navigate through the ensuing chaos as buildings collapsed around them and people were incinerated.
