Navigate Test Chambers 13, 14, and 15 in Portal Reloaded using lasers, time portals, and reflector cubes. This guide details the steps to solve each chamber and progress.
Walkthrough
- 1Test Chamber 13: Place portals as shown in the image to redirect the laser. Use a time portal to move the laser into the future. Travel through the time portal, potentially taking some damage. Rearrange portals in the future to direct the laser into the target, then exit through the door.
- 2Test Chamber 14: Travel to the present using a time portal. Summon a reflector cube and position it as shown. Use a portal to bring a laser through the first node, then reflect it into the next two nodes. Travel to the future. Use portals to bring a laser into the present through the time portal, ensuring it passes through the node. Retrieve the reflector cube from the future and bring it to the present. Position the present reflector cube to hit all three nodes. Adjust as needed. Travel back to the future to retrieve the future reflector cube and bring it to the present via a time portal. Position this cube to reflect the laser into the receiver, completing the chamber.
- 3Test Chamber 15: Go through the particle field to the left. Place a portal where the laser hits the wall and a time portal on the opposite wall. Travel through the time portal to the future to bypass the particle field. Return to the present using another time portal on the other side. Place a portal on the upper wall to direct the laser to the first receiver. Travel to the future and place a portal on the small wall in the laser room to shoot the receiver. Return to the present. The laser should power an elevating platform. Stand on it and shoot a time portal behind the node to raise the platform further and summon a reflector cube. Place this cube on the lip above the second receiver. Travel to the future. Retrieve the future reflector cube and bring it to the present via a time portal in the laser room. Position it to reflect the laser into the second receiver through the node. To bypass the particle field, use a portal on the other side or a time portal. Reach the present on the other side of the particle field. Climb the stairs and use a portal on the upper wall to hit the third receiver. Move the reflector cube onto the switch to complete the chamber.
