Urban Chaos, formerly known as Opposing Force 2, is a single player mod for Half-Life 2 which aims to create an unofficial sequel to the 1999 GoldSrc engine game, Opposing Force.
On June 23, 2014, the creators announced that development has been halted and subsequently released all of the mod's assets onto GitHub in an effort to enable community collaboration on the project.[1][2] One such effort, titled Opposing Force 2: Lost, released as an open beta in January 2018, but it was removed soon after for unknown reasons.
Development for the official mod was revived in 2022 under the name Urban Chaos.
The story takes place on the eve of the Seven Hour War as Adrian Shephard. He has to struggle his way with his fellow comrades from the Phoenix Command, with the main objective of stopping the construction of a Combine Citadel. In his journey, he will find out what has happened to the world moments before the Seven Hour War.
