This article describes the Half-Life 2: Episode Two storyline, chapter by chapter.

Continuing the plot of Half-Life 2 and Episode One, Episode Two consists of seven chapters telling the story of [Gordon Freeman](https://half-life.fandom.com/wiki/Gordon_Freeman "Gordon Freeman") and [Alyx Vance](https://half-life.fandom.com/wiki/Alyx_Vance "Alyx Vance")'s journey through the [Outlands](https://half-life.fandom.com/wiki/Outlands "Outlands") to a [large Resistance base](https://half-life.fandom.com/wiki/White_Forest "White Forest") named after the forest. After the destruction of the [Citadel](https://half-life.fandom.com/wiki/Citadel "Citadel"), the [Combine](https://half-life.fandom.com/wiki/Combine "Combine") are working to open a massive superportal to call for reinforcements. [Combine Advisor](https://half-life.fandom.com/wiki/Combine_Advisor "Combine Advisor") pods have been scattered throughout the region. The destruction of the Citadel, as explained by Dr. Kleiner's broadcast in Episode One, has inflicted a portal and communications blackout on Earth-stationed Combine forces, leaving them isolated and disorganized. A crucial part of the plot is the transmission packet which the Combine sacrificed the Citadel to send, a copy of which Alyx and Gordon stole before making their escape. It contains information relating to the location of the [Combine Overworld](https://half-life.fandom.com/wiki/Combine_Overworld "Combine Overworld") and allows the creation of the superportal to be controlled from the "other side". This information has to be delivered to White Forest so that the Resistance can use it to shut down the superportal and prevent an even greater Combine invasion.
