Portal Walkthrough HL2 Ep2: Which Guide You Need
Portal and Half-Life 2: Episode Two are different games, so the walkthrough you need depends on the one you are playing. Here is how to tell which is which and where to look.
In this article
A portal walkthrough is probably not the guide you need for HL2 Ep2, because Portal and Half-Life 2: Episode Two are two different games. [1] Portal walkthroughs take you through the test chambers of Portal, which came bundled in Valve's The Orange Box. [2] If you are stuck on a puzzle in Portal, that is the guide to use.

Episode Two walkthroughs cover Half-Life 2: Episode Two, so they follow that game's story and locations instead. [1] For example, one Episode Two guide opens with a chapter called To The White Forest and is split into seven pages. [1] Pick the chapter that matches where you are, not the one with the closest title. For more detail, see Half-Life 2 Episode 2 Walkthrough.
Before you search, check the game title on your screen or in your library. If it says Portal, search for a Portal walkthrough. If it says Half-Life 2: Episode Two, search for an Episode Two walkthrough. The rest of this article shows how to tell which guide fits your game.
Why does Episode Two mention a portal at all?
The portal in Episode Two is a story event, not the portal gun from Portal. A portal storm appears to come from the Citadel ruins, destroys the damaged rail bridge, and opens a path into a mine shaft for Alyx and Gordon [3].
This storm is part of the Half-Life story. Because of that, a Portal walkthrough will not help you when you reach it.
What to do if you are stuck
If you are playing Episode Two and get stuck after the storm, look for a walkthrough titled for Episode Two. A Portal walkthrough would send you to test chambers from a different game, so it cannot show you the way through the mine shaft.
For example, say you are in the shaft and cannot find the next route. The Episode Two walkthrough is the guide that covers that part of the story, so open it instead of the Portal guide.
Where do you find the Portal walkthrough?
The Portal walkthrough is on IGN, and you will find it listed under Half-Life 2: Orange Box. That is where Portal was bundled, so search for it under the Orange Box title rather than Half-Life 2 alone. The page is headed "Walkthrough for Valve Corporation's Orange Box - Portal - Released in 2007" [2].
What the guide covers
The walkthrough is written to "walk you through the stages of Valve's amazing mindtwisting puzzle masterpiece: Portal" [2]. It is a step-by-step guide, so each stage builds on the one before it.
Use it one chamber at a time
You don't have to read it from start to finish. Most players use it when they hit a wall. If you are stuck on a chamber where a switch seems out of reach, find that stage in the guide, read only that section, and go back to your game.
Keep the page open in a second window or on your phone while you play. That way you can look up one chamber without reading past the puzzles you have not reached yet.
Where do you find the Half-Life 2: Episode Two walkthrough?
If you are stuck on one puzzle or fight, start with the chapter walkthrough. Portforward.com has one titled To The White Forest, which covers a chapter of Episode Two [1]. Open it when you only need help with that spot, and skip the rest of the chapter.
A guide for the full list of tasks
For a wider view, the Steam Community achievements guide for Episode Two is the better pick. It is dated Sep 29, 2023, and it includes strategies and images [4]. Because the guide is packed with detailed explanations, it also works well if you like to read ahead before you try a section.
Choosing between them
Pick the chapter guide when you are stuck in one place. It answers one question quickly, so you can get back to playing.
Pick the achievements guide when you want the full list of tasks. It covers the whole episode, so you can work through everything in the game rather than one chapter at a time.
What should you do next?
Match the walkthrough to the game on your screen, and you get the right help first time. If you are playing Portal, open the Portal walkthrough for the Orange Box version. It is listed under Half-Life 2: Orange Box, the collection where Portal was bundled, so search under that title. [2]
If you are in Episode Two, open the chapter walkthrough that matches your location. Episode Two's walkthrough is divided into pages, and the first is To The White Forest. [1] Once you know which game you are in, the walkthrough link will take you to the right chapter or chamber.
