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 mechanics.

Test Chamber 13: Place portals as shown in the image to redirect the laser. Use a time portal to move the laser into the future. Once in the future, rearrange portals to direct the laser into the target. You may need to take some damage from the laser to travel through the time portal.

Test Chamber 14: Begin by taking a time portal to the present. Summon a reflector cube and position it in the designated area. Use a portal to guide 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. Position the present reflector cube to hit all three nodes. If necessary, return to the future to retrieve the future reflector cube and bring it back to the present. 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 frequent use of time portals. 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 the future to bypass the particle field. On the other side, use another time portal to return to the present. Place a new portal on the upper wall so the laser hits the first receiver. Travel to the future and place a portal in the laser room to direct the laser at the receiver. Return to the present. The laser should now 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 on the lip above the second receiver. Travel to the future and bring the future reflector cube back to the present via a time portal in the laser room. Position it to reflect the laser to the second receiver through the node. To reach the other side of the particle field without passing through it, use a 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.
