Laser Drills

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

This guide covers the laser-focused test chambers in Portal Reloaded, specifically Test Chambers 13, 14, and 15. We'll detail the steps required to solve each chamber using portals, time portals, and reflector cubes.

Test Chamber 13:

1. Place portals as shown in the image.
2. Use a portal to move the laser sideways and a time portal to send it into the future. You may take damage from the laser to travel into the future.
3. Once in the future, rearrange portals without affecting the present.
4. Position portals so the laser goes directly into the target to open the exit door.

Test Chamber 14:

1. Start by taking a time portal to the present.
2. Summon a reflector cube from the switch in the center and position it in the present as shown.
3. Use a portal to bring a laser through the first node, then use it to reflect the laser into the next two nodes.
4. Travel to the future.
5. Use portals as shown 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. If you moved the future cube, return to the future to retrieve it again.
8. 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 to 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 new portal on the upper wall so the laser hits the first receiver.
6. Travel back to the future and place a portal on the small wall in the laser room to aim at 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. Pick up the future reflector cube and run into the laser room.
11. Place a time portal in the laser room to bring the future reflector cube to the present. Position it to reflect the laser into the second receiver through the node.
12. Ensure you are in the present on the other side of the particle field. Climb the stairs and use a portal on the upper wall to hit the third receiver.
13. Move the reflector cube onto the switch to complete the test chamber.
