Portal - 100% Achievement Guide

This is a guide for getting all of the achievements in the game Portal. I have also made a video guide to go along with this and you can also find my written guide over on my website here[www.pandallax.com].

Before we begin, you'll need to go through the entire story and beat the game once. This is because in order to get the "Transmission Received" achievement you must have already beaten the game once. We'll go through the unmissable story achievements first, then the random story achievements, the collectables throughout the story, and then finally we'll go over the advanced and challenge maps.

With that out of the way let’s start going through how to get these achievements.

You'll get this achievement on Chamber 11 of the story once you pick up the orange portion of the Portal gun. The link to the portion of the video where this is covered is here.

This achievement you'll get at the very end of Chamber 17. Once you throw your companion cube bud into the incinerator the achievement will pop up. The link to the portion of the video where this is covered is here.

This achievement you'll get at the end of Chamber 19. Once you get to the giant fire pit and portal over to safety the achievement will pop up. The link to the portion of the video where this is covered is here.

You'll get this achievement at the very end of the game after you have defeated GlaDos. The link to the portion of the video where this is covered is here.

For this achievement you'll need to grab a turret and use it to physically knock another turret over. You can do this on Chamber 16 with any of the turrets on the level. (And there are a lot.) The link to the portion of the video where this is covered is here.

You can get this achievement on Chamber 15 and a few others, but this is the one that I did it on. You just need to put a portal on the ceiling above you and one on the floor directly beneath it so that you infinitely fall through. Eventually the achievement will pop up. The link to the portion of the video where this is covered is here.

For this one you can get it done close to the very end of the game in the giant room with a muddy trench at the bottom. Once you get all the way up to the top you can put a portal on the slanted platform directly below you, and one on the top one across from you. If you line it up correctly you'll fly through a few times and get the achievement to pop up. The link to the portion of the video where this is covered is here.

To get this one you have to go through the story mode and knock down all possible cameras in one go (33). If you get to the end of the game it will reset your counter so be sure to do all of them in one play through. In the video guide this is covered from 2:14 to 11:38.

To get this one you'll need to find all 26 of the hidden radios and take them to catch a signal for a Morse code. Before we begin, you'll need to go through the entire story and beat the game once. This is because in order to get the "Transmission Received" achievement you must have already beaten the game once.In the video guide this is covered from 2:14 to 12:57.

For this one you'll need to complete 2 of the advanced maps. For the purpose of this guide we'll assume you're doing them in order. For a video guide of maps 13 and 14 go here.

For this one you'll need to complete have completed 4 of the advanced maps. So the next 2 maps to go through would be map 15 and map 16. For a video guide of maps 15 and 16 go here.

For this one you'll need to complete all 6 of the advanced maps. So you'll need to get through advanced maps 17 and 18. For a video guide of maps 17 and 18 go here.

The most efficient way to get these is to go ahead and get gold medals on all of them so that you get all three of them at the same time. Below are the video guides for the challenges on each map.

There is also a way to get these very easily by using the developer console to give yourself no clip. In order to do this you'll need to go into the options, to keyboard, advanced, and enable developer console. For me the default to open the console was the ` key. When you open it you'll need to copy and paste the command below into the console and hit enter. You can also change the key that it's bound to for whatever you want to use. The video portion of the guide for this is here.


bind / "sv_cheats 1; god; noclip '; sv_cheats 0"
