Navigate Test Chambers 13, 14, and 15 in Portal Reloaded. Learn how to use lasers, time portals, and reflector cubes to solve complex puzzles and advance through the game.

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

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 move it into the future. You may take some damage from the laser to travel into the future. Once in the future, rearrange the portals so the laser directly hits the target. Proceed through the door.

Test Chamber 14

First, travel to the present using a time portal. Summon a reflector cube and position it in the present as indicated. Use a portal to bring a laser through the first node, then use this to reflect the laser into the next two nodes. Travel to the future.

In the future, use portals to direct 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 into the present via a time portal. Adjust the reflector cube in the present to ensure the laser hits all three nodes. If necessary, return to the future to retrieve the cube again.

Finally, position 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 reach the future, bypassing the particle field. Head to the other side of the room and use another time portal to return to the present, now on the other side of the particle field.

Place a new portal on the upper wall so the laser hits the first receiver. Travel back to the future and place a portal on the small wall in the laser room to aim at the receiver. Return to the present. The laser should now be hitting the first receiver, powering an elevating platform. Stand on this platform and place a time portal behind the node to raise the platform further.

This will allow you to 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 back to the present using a time portal within the laser room. Position it to reflect the laser into the second receiver.

To proceed, you need to reach the other side of the particle field without passing through it. Use an existing portal or a time portal to get to the present on the other side. 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.
