Navigate Test Chambers 13, 14, and 15 in Portal Reloaded. Learn how to manipulate lasers and time portals 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 and time portals to solve puzzles.

Test Chamber 13: Begin by placing 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 portals 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 and position it in the present as indicated. Use a portal to direct a laser through the first node, then use this beam to reflect the laser 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. Adjust the present reflector cube to hit all three nodes. If necessary, return to the future to retrieve the future reflector cube again and bring it to the present. Finally, position the future reflector cube to reflect the laser into the receiver, completing the chamber.

Test Chamber 15: Start 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. Proceed to the other side of the room and use another time portal to return to the present, now on the far side of the particle 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 on the small wall in the laser room to aim at the receiver. Return to the present. The laser should now be hitting the upper receiver, powering 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. Retrieve the future reflector cube and bring it 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, use a portal or a time portal to bypass it, ensuring you are 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.
