City Rebellion is an episodic mod intended to have the player take on the role of one of the citizens of a city dominated by the Combine.
Chapter 1: The player plays as an unnamed character who is assigned the task of operating an observation outpost in an abandoned warehouse. The level picks up just as the player is messaged by a character named "CHandler", alerting them that the outpost has been discovered, and a Combine raid is minutes away.
Chapter 2: The player, having escaped the Combine raid heads over to the underground rebel base until the Combine manages to find the base and attacks again.
The first two of five chapters have been released. Work has begun on chapter three.
