}}

{{Show achievement|Portal 2|Smash TV|Hard
| Half way throughout Test Chamber 21 you will be interrupted by Wheatley, who will offer you an escape route. The achievement will be obtained as soon as you begin your escape.}}

{{Show achievement|Portal 2|Stalemate Associate| Easy
 
| Upon facing GLaDOS for the second time, you will be asked to place Wheatley in an Aperture Science Core Transfer Receptacle. After a disagreement between Wheatley and GLaDOS on whether the process should go ahead, you will be asked as a Stalemate Associate to press the Stalemate Associate Button. Doing so will reward you the achievement
* '''[[Portal 2 Chapter 8 Test Chamber 1|Test Chamber 1]]''': Lift up a box using the funnel (make sure you are on the lower section) and, using its now gained height, fling it at Wheatley.
* '''Test Chamber 2''': Do basically the same thing from Test Chamber 1.
* '''Test Chamber 3''': The same as Test Chambers 1 and 2, but make sure you are in the first section of the chamber.
* '''Test Chamber 4''': Pick up the turret behind the button and aim it at Wheatley. It will not shoot until you let go, setting it upright.
* '''Test Chamber 5''': There are two monitors in this chamber. They both are smashed by lifting a box in a funnel and flinging it, but the exit portals are in two different locations. The first is on the wall in which the funnel is being projected on, around the center (This will take experimentation.) The second is on the very right of the angled surface that you go through on your way to the exit.
* '''Test Chamber 6''': Launch yourself on the Aerial Faith Plate.
* '''Test Chamber 11''': Burn him with the Discouragement beam and the Redirection cube. you will need to use the box to get the beam on a portal conductive surface, then use portals to get the beam to hit Wheatley.
* '''Test Chamber 12''': When you are in the place where you would normally use the cube to open the door, burn the monitor.
* '''Test Chamber 15''': Do the same thing as Test Chambers 1, 2, and 3.
* '''Test Chamber 16''': (Tip: this is extremely hard to get in one try. Save at every point noted with F6.) Do the test normally, however at the part where you coat turrets in [[Repulsion Gel]] (save before this) You must only coat '''two''' of the turrets, leaving one alive. (save now as well) Then, using one of the portal surfaces on each side of the turret platform, jump on the platform while pressing the crouch button to avoid bouncing on gel. Grab the one remaining turret, and use it to shoot Wheatley and earn the achievement.
 
There is still one more monitor in the penultimate map [[Portal 2 Chapter 9 Morton's Fork|Morton's Fork]], but it does not count as one in this achievement. You have to destroy '''all the 11 monitors above''' to unlock the achievement. While Wheatley is informing you of your death option, place one portal underneath the Pneumatic Diversity Vent where the bombs come out. Put the other portal on the wall to your left facing Wheatley's TV. When you press the button, the bombs should fly through and destroy the TV, causing Wheatley to immediately stop talking ("All right, I'll take that as a no, then.") and leave.

{{Show achievement|Portal 2|Tater Tote|Easy
{{Show achievement|Portal 2|Portal Conservation Society|Hard
| Near the end of Chapter 6 you will reunite with GLaDOS in her potato form. Simply pick her up to receive the achievement.
| This achievement takes place on [[Portal 2 Co-op Course 3 Chamber 3]], and is possible to obtain with only one set of portals. Place one portal at the receiving end of the Hard Light Bridge, then place the other portal on a nearby wall. Enter the portal on the wall and walk over to the bridge emitter. Move on the emitter so that you can see the white surface of the overhead panels, then fire a portal so that the Hard Light Bridge runs under the Vital Apparatus Vent. Press the button in the center of the wall by the Light Bridge and have your partner catch the ball that drops out of the vent. Place the ball on the receptacle and proceed into the next part of the chamber. Fire a portal at the receiving end of the Hard Light Bridge, then line up the second portal on the ceiling so that using the Aerial Faith Plate bounces you off the vertical light bridge and into the exit area. To reset, use {{code|changelevel mp_coop_catapult_wall_intro}}.
}}
}}
{{Show achievement|Portal 2|Vertically Unchallenged|Medium
{{Show achievement|Portal 2|Still Alive|Very Hard
| This achievement will be awarded after a series of Repulsion Gel based tests during Chapter 6.
| Get through the excursion funnels course in one run... with no deaths. Watch out for test chambers:
* '''3''' Voice chat, the timer, and a clear understanding of the course/practice are highly recommended.
* '''6''' Make sure you do not make a very common mistake. Do not go into the spikes at the end of the excursion funnel/practice.
* '''8''' This is a trust test so do not fool around. It's easy if you try/practice.
* '''9''' Do not shoot the wrong portal whether you are doing the Hard Light shields or the funnels... practice. Also, don't try to get Party of Three (see above).
 
Practice on all of these stages! That cannot be stressed enough! If you mess up, you can save a little bit of time by having the host type {{code|changelevel mp_coop_tbeam_redirect}} in the developer console to reload the first map instead of going back to the hub.

}}
{{Show achievement|Portal 2|Stranger Than Friction|Medium
{{Show achievement|Portal 2|Professor Portal|N/A
| Identical to how Vertically Unchallenged worked, you will need to complete a series of Propulsion Gel based tests during Chapter 7.  
| Find random partners online, and immediately leave the game if you do not see the opening film. When you find a beginner, exit the game, friend them, and invite them. This will take a long time depending on how lucky you are. Alternatively, this achievement can be very easy if you already have friends on Steam who have ''Portal 2'', but haven't done co-op mode yet.

In one of the many times you and your partner are floating through a funnel, if you look straight to your left, (on the same wall where your partner shoots Hard Light Bridges) you will see a portal conductive surface that you would not normally pay attention to. Shoot a portal there so that the funnel is coming out of it and you float through the funnel. If you look to your left you will see a companion cube behind doors that will open. You will then hit a spike wall and die, so don't try this while attempting Still Alive. To restart, use changelevel mp_coop_tbeam_end.
Final Transmission
Final Transmission
Find the hidden signal in one of the Rat Man's dens
Difficulty: Medium
How to obtain: When at the switch near the exit of Chapter 2 Test Chamber 6, hit the switch and wait for all the trash to fall. Retrieve the radio from wherever it landed and go back to the switch. On the left wall at the opposite end of the chamber, there will be a portal-able surface; remember where this is. Portal back to the start of the chamber with the radio. Place a portal on the portalable-surface mentioned earlier and the other portal on the portalable surface the Aerial Faith Plates will throw you into, jump on the Aerial Faith Plates, and you will fly into one of Rattman's Dens—taking the radio in here will get you this achievement. This achievement is a direct follow-up to the Transmission Received achievement from the first game.

Difficulty: Medium
How to obtain: There are two sets of three vitrified doors in Chapter 6. The first set is on a catwalk opposite the entrance to Pump Station Alpha; exit the lift and turn to the seven-o'-clock position. The second set is in the room above the control room where you find potato GLaDOS. Walk into the room from the top catwalk. Jump on the furniture in the back-left corner and go through the doors.

Schrodinger's Catch
Catch a blue-painted box before it touches the ground
Difficulty: Medium
How to obtain: On Chapter 6, Enrichment Sphere 3 save the game before dropping Repulsion Gel on the cube. Release the gel and try and catch the cube; if it hits the ground, load the earlier save. An alternate method of obtaining this achievement is to drop a little bit of Repulsion Gel on the cube, and then before it breaks out of the glass, drop water on it to stop the bouncing. Simply walk up to the cube and pick it up without touching the ground to get the achievement.

Complete Test Chamber 10 in 70 seconds
Difficulty: Hard
How to obtain: Self-explanatory. Keep practicing the puzzle until you are confident at the sequence of puzzle elements and how to maneuver quickly to each one. You can do this in Challenge Mode for easy restarts (and to be on the leaderboard), or use changelevel sp_a2_ricochet. The achievement's timer starts as soon as you enter the test chamber, not the moment the map loads.
Smash TV
Smash TV
Break 11 test chamber monitors
Difficulty: Hard
How to obtain: In these test chambers in chapter 8, Wheatley's TV monitors are able to be smashed in the following ways:
  • Test Chamber 1: Lift up a box using the funnel (make sure you are on the lower section) and, using its now gained height, fling it at Wheatley.
  • Test Chamber 2: Do basically the same thing from Test Chamber 1.
  • Test Chamber 3: The same as Test Chambers 1 and 2, but make sure you are in the first section of the chamber.
  • Test Chamber 4: Pick up the turret behind the button and aim it at Wheatley. It will not shoot until you let go, setting it upright.
  • Test Chamber 5: There are two monitors in this chamber. They both are smashed by lifting a box in a funnel and flinging it, but the exit portals are in two different locations. The first is on the wall in which the funnel is being projected on, around the center (This will take experimentation.) The second is on the very right of the angled surface that you go through on your way to the exit.
  • Test Chamber 6: Launch yourself on the Aerial Faith Plate.
  • Test Chamber 11: Burn him with the Discouragement beam and the Redirection cube. you will need to use the box to get the beam on a portal conductive surface, then use portals to get the beam to hit Wheatley.
  • Test Chamber 12: When you are in the place where you would normally use the cube to open the door, burn the monitor.
  • Test Chamber 15: Do the same thing as Test Chambers 1, 2, and 3.
  • Test Chamber 16: (Tip: this is extremely hard to get in one try. Save at every point noted with F6.) Do the test normally, however at the part where you coat turrets in Repulsion Gel (save before this) You must only coat two of the turrets, leaving one alive. (save now as well) Then, using one of the portal surfaces on each side of the turret platform, jump on the platform while pressing the crouch button to avoid bouncing on gel. Grab the one remaining turret, and use it to shoot Wheatley and earn the achievement.

There is still one more monitor in the penultimate map Morton's Fork, but it does not count as one in this achievement. You have to destroy all the 11 monitors above to unlock the achievement. While Wheatley is informing you of your death option, place one portal underneath the Pneumatic Diversity Vent where the bombs come out. Put the other portal on the wall to your left facing Wheatley's TV. When you press the button, the bombs should fly through and destroy the TV, causing Wheatley to immediately stop talking ("All right, I'll take that as a no, then.") and leave.

Complete Chamber 3 in the Hard-Light Surfaces co-op course using only 5 total portal placements
Difficulty: Hard
How to obtain: This achievement takes place on Portal 2 Co-op Course 3 Chamber 3, and is possible to obtain with only one set of portals. Place one portal at the receiving end of the Hard Light Bridge, then place the other portal on a nearby wall. Enter the portal on the wall and walk over to the bridge emitter. Move on the emitter so that you can see the white surface of the overhead panels, then fire a portal so that the Hard Light Bridge runs under the Vital Apparatus Vent. Press the button in the center of the wall by the Light Bridge and have your partner catch the ball that drops out of the vent. Place the ball on the receptacle and proceed into the next part of the chamber. Fire a portal at the receiving end of the Hard Light Bridge, then line up the second portal on the ceiling so that using the Aerial Faith Plate bounces you off the vertical light bridge and into the exit area. To reset, use changelevel mp_coop_catapult_wall_intro.
Still Alive
Still Alive
Complete Course 4 with neither you nor your co-op partner dying
Difficulty: Very Hard
How to obtain: Get through the excursion funnels course in one run... with no deaths. Watch out for test chambers:
  • 3 Voice chat, the timer, and a clear understanding of the course/practice are highly recommended.
  • 6 Make sure you do not make a very common mistake. Do not go into the spikes at the end of the excursion funnel/practice.
  • 8 This is a trust test so do not fool around. It's easy if you try/practice.
  • 9 Do not shoot the wrong portal whether you are doing the Hard Light shields or the funnels... practice. Also, don't try to get Party of Three (see above).

Practice on all of these stages! That cannot be stressed enough! If you mess up, you can save a little bit of time by having the host type changelevel mp_coop_tbeam_redirect in the developer console to reload the first map instead of going back to the hub.

After completing co-op, complete Calibration Course online with a friend who hasn’t played before
Difficulty: N/A
How to obtain: Find random partners online, and immediately leave the game if you do not see the opening film. When you find a beginner, exit the game, friend them, and invite them. This will take a long time depending on how lucky you are. Alternatively, this achievement can be very easy if you already have friends on Steam who have Portal 2, but haven't done co-op mode yet.
