The Verses — LASERS Walkthrough

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. You may take some damage to travel into the future. Once in the future, rearrange portals without affecting the present. Position portals so the laser goes directly into the target to complete the chamber.

Test Chamber 14: First, travel to the present using a time portal. Summon a reflector cube and position it in the present as shown. Use a portal to bring a laser through the first node and reflect it into the next two nodes. Then, 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 via a time portal. Adjust the present reflector cube to hit all three nodes. If needed, return to the future to retrieve the future reflector cube again and bring it 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: 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 reach the future, bypassing the particle field. Head 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. Place a new portal on the upper wall to direct the laser to the first receiver. Travel back to the future and place a portal in the laser room to shoot at the receiver. Return to the present. An elevating platform near the switch will power up. 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 pick up the future reflector cube. Bring it back to the present by placing a time portal in the laser room. Position the cube 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 in the present on the other side, climb the stairs and place a portal on the upper wall to hit the third receiver. Finally, move the reflector cube onto the switch to complete the test chamber.
