Complete walkthrough for Portal Reloaded's Test Chambers 13, 14, and 15, focusing on advanced laser manipulation and time portal mechanics to solve complex puzzles.

This guide covers Test Chambers 13, 14, and 15 of Portal Reloaded, focusing on the strategic use of lasers, portals, and time portals to solve the puzzles.

Test Chamber 13

Start by placing portals as shown in the image. Use a portal to redirect the laser sideways, and a time portal to send it into the future. You may take some damage from the laser to travel into the future. Once in the future, rearrange the portals without affecting the present. Position them so the laser directly hits the target, then proceed through the door.

Test Chamber 14

First, travel to the present using a time portal. Summon a reflector cube from the central switch and position it in the present as indicated. Use a portal to direct 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 designated node. Retrieve the reflector cube from the future and bring it to the present via the time portal. Ensure the present reflector cube hits all three nodes; adjust its position if necessary. Return to the future if you moved the cube. Place the future reflector cube at the end of the nodes to reflect the laser into the receiver, completing the chamber.

Test Chamber 15

Begin by passing 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. Proceed to the other side of the room and use another time portal to return to the present, now on the other side of the field. Place a new portal on the upper wall above the laser room so the laser hits the first receiver. Travel back to the future and place a portal in the laser room to direct the laser at the receiver. Return to the present. The laser should still be hitting the first receiver, powering an elevating platform. Stand on the platform and place a time portal behind the node. This will raise the platform, allowing you to summon a reflector cube. Place this cube on the lip above the second receiver. Travel to the future and bring the future reflector cube into the laser room in the present using a time portal. Position it to reflect the laser into the second receiver through the node. To proceed without crossing the particle field, use a portal on the other side or a time portal. You need to be in 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. Finally, move the reflector cube onto the switch to complete the test chamber.
