Detailed walkthrough for Portal Reloaded's Test Chambers 13, 14, and 15, focusing on using lasers, time portals, and reflector cubes to solve puzzles.

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

Test Chamber 13: Place portals as shown to redirect the laser. Use a time portal to move the laser into the future, then rearrange present portals to direct the laser into the target. Travel through the time portal to reach the exit.

Test Chamber 14: Start by taking a time portal to the present. Summon a reflector cube and position it to redirect the laser through the first node. Travel to the future. Use portals to bring a laser into the present through the time portal, ensuring it hits the node. Retrieve the future reflector cube and bring it to the present. Adjust the present reflector cube to hit all three nodes. Return to the future to move the future reflector cube to the present. Position the present reflector cube to reflect the laser into the receiver, completing the chamber.

Test Chamber 15: Go 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 bypass the particle field in the future. Return to the present using another time portal to be on the other side of the field. Place a portal to direct the laser to the first receiver. Travel to the future, place a portal to shoot the receiver. Return to the present; the laser should power an elevating platform. Stand on it and place a time portal behind the node to raise the platform further, allowing you to summon a reflector cube. Place this cube to hit the second receiver. Travel to the future, retrieve the future reflector cube, and bring it to the present via a time portal. Position it to reflect the laser into the second receiver through the node. To reach the other side of the particle field, use a portal or time portal. On the other side, climb the stairs and use a portal to hit the third receiver. Move the reflector cube onto the switch to complete the chamber.
