Navigate Test Chambers 13, 14, and 15 in Portal Reloaded by mastering laser redirection and time portals. Follow this guide to solve complex puzzles with LASERS.

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

Test Chamber 13

Place portals as shown in the image. Use a portal to move 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 so the laser hits the target. Then, head through the door.

Test Chamber 14

First, travel to the present using a time portal. Summon a reflector cube from the switch in the center and position it in the present as shown. Use a portal to bring a laser through the first node, then use the reflector cube to direct 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. Adjust the present reflector cube so it hits all three nodes. If necessary, return to the future to retrieve the future reflector cube again.

Finally, place the future reflector cube to reflect the laser into the receiver, completing the chamber.

Test Chamber 15

Start by going 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. 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 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 the platform and place a time portal behind the node to raise it further.

This will allow you to summon a reflector cube. Place this cube on the lip above the second receiver. Travel to the future. Pick up the future reflector cube and return to the present by placing a time portal in the laser room. Position this cube to reflect the laser into the second receiver through the node.

Now, 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.
