Horror Elements & Survival Tips

Navigate the challenging 'Lasers' chapter of Portal Reloaded. Learn essential strategies and tips for using lasers, time portals, and reflector cubes to overcome test chambers.

This guide covers Test Chambers 13, 14, and 15 of Portal Reloaded, focusing on the strategic use of lasers, time portals, and reflector cubes. Learn how to manipulate time and redirect beams to solve complex puzzles and progress through the game.

Test Chamber 13: Place portals as shown to use a portal to move the laser sideways and a time portal to send it into the future. You can take some laser damage to travel into the future. Once in the future, rearrange portals so the laser hits the target, then exit through the door.

Test Chamber 14: Travel to the present via a time portal. Summon a reflector cube and position it as shown. Use a portal to direct a laser through the first node, then use the reflector cube to guide 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. Adjust the present reflector cube to hit all three nodes. If necessary, return to the future to retrieve the cube again. Finally, position the future reflector cube to direct the laser into the receiver, completing the chamber.

Test Chamber 15: Pass 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. Return to the present using another time portal to be on the other side of the field. Place a portal on the upper wall to direct the laser to the first receiver. Travel to the future and place a portal on the small wall in the laser room to hit the receiver. Return to the present; the laser should now power an elevating platform. Stand on the platform and place a time portal behind the node to raise it, 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 back to the present using a time portal in the laser room. 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 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.
