Obtaining Portal 2 achievements: Difference between revisions

| In Test Chamber 06 of Chapter 2, stand at the switch and place one portal on the right-hand sloped surface. Place the other portal on the panel above the button and press the switch twice. Alternatively, press the switch in Wheatley's very first test chamber.

| During the third chapter, Test Chamber 12 will introduce the new Hard Light Bridge. Similar to the Undiscouraged achievement, you will need to complete this introductory chamber to obtain the achievement.

| In the final area of the excursion funnel section of co-op mode, you will be outside the official testing track. 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.

| When at the switch near the exit of [[Portal 2 Chapter 2 Test Chamber 6|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.

| There are three sets of three {{W|vitrification|vitrified}} doors in Chapter 6. The first set is on the upper catwalk in the lake area, immediately after the hatch. The second set is on a catwalk opposite the entrance to Pump Station Alpha; exit the lift and turn to the seven-o'-clock position. The third 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.

| In the area within this test that gives this achievement its difficulty, timing is everything. Make sure you and your partner know what you're doing before attempting this. If you lose one box, have the host type {{code|changelevel mp_coop_multifling_1}}in the developer console to reload the map.

| Self-explanatory, but make sure you and your partner know what you're doing. If you mess up, have the host (Atlas) reload the map by typing {{code|changelevel mp_coop_paint_red_racer}}in the developer console.

| Self-explanatory. Keep practicing the puzzle until you are confident at the sequence of puzzle elements and how to maneuver quickly to each one.

| In these test chambers, Wheatley's TV monitors are able to be smashed in the following ways: (this must be done in one run.)

* '''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 16''': (Tip: this is extremely hard to get in one try. Save at every point noted.) 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.

* '''Morton's Fork''': If you miss a TV, there is still one more chance in the penultimate map. 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.  

| 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.

| 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.
