Master Portal 2's Test Chamber 5 with this step-by-step guide. Learn how to use portals and lasers with a friend to overcome the spiked barricades and reach the exit.

Alright, let's tackle Test Chamber 5 in Portal 2 co-op. This one's all about coordinating with your partner to navigate some tricky laser and spike mechanics.

Walkthrough
  1. 1
    Player 1: First up, look towards the center wall of the room. You'll see two platforms. Your job is to place portals strategically. Put your first portal on the lower half of the wall near the left-hand platform, and your second portal on the lower half of the wall near the right-hand platform. This sets up the initial movement.
  2. 2
    Player 2: Now, head to the middle of the room and grab that Displacement Cube. You need to aim the laser beam it emits into the receptor on the left side of the room. Doing this will raise a spiked barricade, creating a new path.
  3. 3
    Player 1: Once the spikes are high enough, hop onto the platform that just rose. Then, have Player 2 switch the laser's target. They need to aim it at the receptor on the wall right next to you. This action will cause your platform to lower while the spikes rise even higher.
  4. 4
    Player 2: With Player 1 safely on their platform, rotate the laser beam to your right. Line it up with the receptor on that side. This will make Player 1's platform drop further as the spikes go up.
  5. 5
    Player 1: Now, you'll need to carefully jump into the spiked barricade. Keep doing this until you've created enough space to get through. Once you've cleared the spikes, jump over the laser beam and place your exit portal on the wall just to the left of the actual exit door. This is crucial for Player 2 to join you.
  6. 6
    Player 2: With Player 1's exit portal set, step through the first portal you placed earlier. You'll emerge from Player 1's exit portal right next to them, and you'll have completed the chamber!
Tips
  • Communication is key here! Make sure you and your partner are talking through each step, especially when switching the laser targets.
  • Don't rush the spiked barricade part. It's better to take a moment to create the right amount of space than to get hit and have to reset.
  • The timing for switching the laser can be a little finicky. If Player 1's platform doesn't move as expected, have Player 2 try readjusting the laser's aim slightly.
