Navigate Portal Reloaded's challenging laser puzzles. This guide provides step-by-step walkthroughs for Test Chambers 13, 14, and 15, detailing laser redirection and time portal mechanics.

This section covers the use of lasers and time portals to solve puzzles in Portal Reloaded. We will go through Test Chambers 13, 14, and 15.

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 the laser into the future. You may take some damage to travel into the future. Once in the future, rearrange the portals so the laser goes directly into the target. This will allow you to exit the test chamber.

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 this to reflect the laser into the next two nodes. Travel to the future.

In 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 into the present via the time portal. Position the present reflector cube to hit all three nodes. If it doesn't, adjust it. You may need to travel back to the future to retrieve the future reflector cube again if you moved it.

Finally, place the future reflector cube at the end of the nodes to reflect the laser into the receiver, completing the chamber.

Test Chamber 15

This chamber involves multiple steps and frequent use of time portals. 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. Once on the other side, use another time portal to return to the present.

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 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 near the switch. Stand on the platform and place a time portal behind the node to raise the platform further, allowing you to summon a reflector cube.

Place the reflector cube on the lip above the second receiver. Travel to the future by placing your time portal conveniently. Retrieve the future reflector cube and return to the present via a time portal placed within the laser room. Position this cube to reflect the laser into the second receiver through the node.

Now, you need to reach the other side of the particle field without passing through it. Use an existing portal on the other side or a time portal to bypass it. Once in the present on the other side, 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 test chamber.
