Introduction:
Aperture Science welcomes you. Portal 2 is the sequel to the critically-acclaimed game Portal, which came as part of The Orange Box back in 2007. The game takes place in the Half-Life universe, and you play as a woman named Chell, who must use her Portal gun to solve various puzzle rooms (known as "Test Chambers") while travelling through the old Aperture Science Labs. Along the way, you’ll meet various characters such as the little robot Wheatley and the iconic villain from the first game GLaDOS. Portal 2 brings with it a new co-op mode, which is a separate campaign from the single-player story. Not only will you be having fun with a co-op partner, you'll also both face increasing difficulty of puzzles as you progress. Overall, this game is very rewarding if you can master the puzzles without the assistance of a spoiler walkthrough.
Walkthrough:
Step 1: Playthrough the single-player story
The first thing to do is to play through the game and clear the single-player story. It starts out easy, teaching you the basics of using Portals, Companion Cubes, etc. The further you progress in the game, the harder the test chambers become. Towards the end, some of them will challenge your mind, and you are likely to get through them with some perseverance. Be aware that there are many exploration trophies that you can forget to get along the way during the story. Don’t be afraid to explore the area a little and go out of your way to do things (like finding Rat Man Dens). In fact, if you are having trouble with a puzzle, you might just end up finding the solution by exploring a bit!
Below is the trophy breakdown by chapters including all story-related trophies. As you progress, refer to the trophy guide for specifics on how to unlock each exploration trophy in their respective chapter(s) during your single-player playthrough. As several trophies could be attained in multiple chambers, chapters, and/or areas:
Chapter 1: The Courtesy Call
Wake Up Call (story-related)

Step 2: Clean-up using Chapter Select
After clearing the story, it’s time top mop-up any remaining offline trophies you might have missed. You can use Chapter Select via New Game from the Main Menu to do this. You might have to play through certain chambers of the chapter beforehand to get to an area where a trophy is obtainable. Please refer to the trophy guide to see which trophies you need. Since you know all of the test chamber solutions by now, playing through parts of the game won’t be as hard this time around. By the end of this step, you should have all of the offline trophies.
Possible Glitched Trophies:
Refer to the trophy guide for more information to ensure you do not glitch the following trophies:
Tater Tote
White Out
In Co-Op mode, it is possible that some of the progression trophies may not unlock naturally. If this happens, re-check the entrance of each course and check each chamber progression box for the player that is having the issue, as there are likely missing chambers that did not register as completed. Quitting out of the game, re-inviting your partner, and replaying them again should resolve this. Also playing in offline co-op has been confirmed to work as well. Valve has been notified of this issue.
Step 3: Co-op Experience
The Cooperative story is entirely separate from the single-player portion. You play as 1 of 2 robots playing through test chambers that are more complex than single-player, thus requiring the teamwork of both people. You can play through Co-op via online or split-screen. After completing the Calibration Course, you will be in a hub world, which is the main area where you can unlock and choose which co-op courses you want to play through. Each of these courses are separated into test chambers. Be prepared, because the test chambers can be challenging in puzzle nature, especially towards the last few courses. You will need to maintain good communication with your co-op partner in order to get all of the trophies in this step. Mics are highly recommended, and be sure to make use of the in-game tools you learn during the Calibration Course Tutorial for things like specific portal placement, countdown timers, and any other communication needs.
The following section is a breakdown of where you will be able to unlock the following Co-Op trophies:
Anytime in Co-Op
Narbacular Drop
Rock Portal Scissors
Gesticul-8
Mass and Velocity (Course 2)
Four Ring Circus (Test Chamber 01)
Air Show (Test Chamber 01)
Triple Crown (Test Chambers 01-03 or 02-04)
Iron Grip (Test Chamber 06)
Hard-Light (Course 3)
Empty Gesture (Test Chamber 01)
Portal Conservation Society (Test Chamber 03)
Can't Touch This (Test Chamber 06)
Excursion Funnels (Course 4)
Party of Three (Test Chamber 09)
Still Alive (All Chambers)
Step 4: Co-op Clean-up
After completing all of the courses, and obtaining You Saved Science, the whole hub world will be open. Go back and pick up any of the trophies you might have missed. Also, now that you have completed co-op, you will need a friend that has not played Co-Op before and complete the Calibration Course with them for Professor Portal (unobtainable, due to server closure). Alternatively, you and your current co-op partner could make alternate PSN accounts and friend each other for this trophy as well. You also want to get Friends List With Benefits (unobtainable, due to server closure) out the way so do that at the same time as Professor Portal.
