Portal 2 Achievements and Trophies Guide

Obstacle Building

15 Points
Bronze Trophy

Complete all test chambers in the Excursion Funnels co-op course

Simply complete all the test chambers in Course 4.


Party of Three

25 Points
Bronze Trophy

Find the hidden companion cube in co-op test chamber

In Course 4, during the second part of test chamber 9, you will use a repulsion wave to float over a set of spikes below. Use another portal in the room below to the right to move your bots to the left as well as a light bridge on the opposite wall  at the far end, near the beginning of the conveyor belt to stop the turrets from entering the area. As you float towards the office at the far end, shoot a portal to the left- on the same wall where the light bridge should be coming from- that will allow a repulsion wave to flow to the right through the opening before the office. Float along to the end and you will find the companion cube sitting in a room.  All you have to do is look at it for the achievement/trophy to pop.


Portal 2 Platinum Trophy (PS3 Only)

Platinum Trophy

Collect all other Portal 2 Trophies

Collect all of the Portal 2 trophies, both single and co-op to get this granddaddy of them all.


Portal Conservation Society

20 Points
Bronze Trophy

Complete Chamber 3 in the Hard-Light Surfaces co-op course using only 5 total portal placements

For this achievement/trophy, use the video for portal placement and techniques. Basically you need to use 3 portals in the first room and 2 in the second. In the second room, you will need to perform a tricky bank shot with your body to land on the exit platform. It will take some practice, but it can be done.


Professor Portal

75 Points
Gold Trophy

After completing co-op, complete Calibration Course online with a friend who hasn’t played before

Once you have completed the co-op campaign with a buddy, find someone who hasn’t played co-op yet and perform the beginning calibration course with them. You can also ask a friend who hasn’t played co-op yet to load the game up for a hug and that will nab you this reward as well as an extra hug since you can’t perform the hug until after the calibration is complete. Sadly, playing split screen doesn’t achieve this.


Rock Portal Scissors

20 Points
Silver Trophy

Win 3 co-op games of rock-paper-scissors in a row

During Course 1, you will get the Rock, Paper, Scissors gesture. Simply keep playing until you win three matches in a row. It may take a minute or four, but it will happen soon enough.


Still Alive

15 Points
Bronze Trophy

Complete Course 4 with neither you nor your co-op partner dying

This may be the toughest achievement/trophy of the bunch. To get this, you need to play through the entirety of course 4 without dying. If you do die, you need to start back at test chamber 1. You cannot restart a test chamber halfway through the course and give it another try. It’s either all or nothing.


Team Building

10 Points
Bronze Trophy

Complete all test chambers in the Team Building co-op course

Simply complete all the test chambers in Course 1.


Triple Crown

15 Points
Bronze Trophy

For this achievement/trophy I chose to complete test chambers 2, 3, and 4 in Course 2. The first one is easy as well, but has more travelling time to do than the next three. Chambers 2, 3, and 4 can easily be finished in less than 60 seconds each- even when you mess up which I so embarrassingly did in chapter 4- as the video shows.


You Saved Science

100 Points
Gold Trophy

Complete all test chambers in all courses of co-op

Simply complete all of the test chambers in Courses 1-5.

    I don't understand how you pulled off the last one. It's the only one I have left to do.
  • Pocotron - April 28, 2011 9:37 p.m.

    Just what the doctor ordered.

    @russman. If you got it for PS3, then you have a steam copy. Go play it on a real game machine Sorry, PC gaming fanboy popped out. No idea how he got out of his locked room... I have most of the single player, but none of my friends have it for the Co-Op (Ok, one does, but he can not take it on steam, if you catch my drift on its state of hacked)
  • russman - April 28, 2011 3:25 p.m.

    I reckon being able to play this on PSN would be an achievement in itself.
  • EnragedTortoise1 - April 28, 2011 noon

    Already got all the story-related ones, I'm waiting for PSN to come back up for the others. Or I could just play with my little brother...

    @ChiChiRocket You could simply ask one of your friends to create a second PSN account once the network is online again. In return, you could of course create a new account for them, so they can get the trophy, too.

    Looks like a good guide for most achievements; however, I only really need Still Alive now and an actual strategy wouldv'e been nice.
  • philipshaw - April 28, 2011 10:10 a.m.

    Thanks for this, missed some of the trophies on my first playthorugh but I will be sure not miss them now
  • ChiChiRocket - April 28, 2011 5:44 a.m.

    This damn PSN issue is quickly closing my window for Professor Portal, as more of my curious friends are starting to rent the game.
  • ejabno - April 28, 2011 3:18 a.m.

    Whoever did the one where you have to break all the test monitors could have used the fling method at the very first monitor. Also, he's soooo slow.
  • WeinerlessSteve - April 28, 2011 3:07 a.m.

    Thanks for the pointers!
