Navigate Test Chambers 13, 14, and 15 in Portal Reloaded, mastering the use of 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 strategic use of lasers, time portals, and reflector cubes.

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 goes directly into the target to complete the chamber.

Test Chamber 14

Begin by traveling to the present using a time portal. Summon a reflector cube and position it in the present as shown. Use a portal to direct a laser through the first node, then use the reflector cube to guide 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 via a time portal. Adjust the reflector cube in the present to ensure it hits all three nodes. If necessary, return to the future to retrieve the cube again. Finally, position the future reflector cube to reflect the laser into the receiver, completing the chamber.

Test Chamber 15

This chamber requires frequent use of time portals. First, pass 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 above the laser room so the laser hits the first receiver. Return 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 power an elevating platform. Stand on the platform and place a time portal behind the node to raise it further, allowing you to summon a reflector cube. Place this cube on the lip above the second receiver. Travel to the future and retrieve the future reflector cube. Bring it back to the present by placing a time portal in the laser room. Position the cube to reflect the laser into the second receiver through the node. To reach the other side of the particle field without going through it, use an existing portal or a time portal. Once on the other side in the present, 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.
