Resource Management — LASERS Guide

Detailed walkthrough for Portal Reloaded's Laser challenges in Test Chambers 13, 14, and 15. Learn to manipulate lasers with time portals and reflector cubes to solve complex puzzles.

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

Test Chamber 13

1. Place portals as shown in the image to redirect the laser.
2. Use a time portal to move the laser into the future.
3. Enter the time portal to advance. You may take some damage from the laser.
4. Once in the future, rearrange portals without affecting the present.
5. Position portals so the laser directly hits the target.
6. Proceed through the exit door.

Test Chamber 14

1. Travel to the present using a time portal.
2. Summon a reflector cube from the central switch and position it in the present as shown.
3. Use a portal to direct a laser through the first node, then use the reflector cube to guide it through the next two nodes.
4. Travel to the future.
5. Use portals to bring a laser into the present through the time portal, ensuring it passes through the node.
6. Retrieve the reflector cube from the future and bring it to the present via a time portal.
7. Ensure the reflector cube in the present hits all three nodes; adjust as necessary.
8. If the future reflector cube was moved, travel back to the future to retrieve it.
9. Place the future reflector cube at the end of the nodes to reflect the laser into the receiver, completing the chamber.

Test Chamber 15

1. Pass through the particle field on the left.
2. Place a portal where the laser hits the wall and a time portal on the opposite wall.
3. Travel through the time portal to the future to bypass the particle field.
4. Proceed 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.
5. Place a portal on the upper wall so the laser hits the first receiver.
6. Travel to the future and place a portal on the small wall in the laser room to shoot the receiver.
7. Return to the present; the laser should be hitting the first receiver, powering an elevating platform.
8. Stand on the platform and place a time portal behind the node to raise the platform further.
9. Summon a reflector cube and place it on the lip above the second receiver.
10. Travel to the future.
11. Retrieve the future reflector cube and run into the laser room.
12. Place a time portal in the laser room to bring the future reflector cube to the present.
13. Position the cube to reflect the laser into the second receiver through the node.
14. To bypass the particle field again, use an existing portal or a time portal. You need to be in the present on the other side of the field.
15. Climb the stairs and place a portal on the upper wall to hit the third receiver.
16. Move the reflector cube onto the switch to complete the chamber.
