Disrupt Weapons (Cayo Perico)

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

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, then use it to reflect the laser into the next two nodes. Travel to the future. Use portals to bring a laser into the present through the time portal, ensuring it goes through the node. Pick up the reflector cube from the future and bring it to the present through the time portal. Ensure the present reflector cube hits all three nodes; adjust as needed. If you moved the future reflector cube, you may need to travel back to the future to retrieve it and bring it to the present again. Finally, place the future reflector cube at the end of the nodes so it reflects the laser into the receiver to complete the chamber.

Test Chamber 15: Start by going through the particle field to the left. Shoot a portal where the laser hits the wall and place a time portal on the other wall. Travel through the time portal to move into 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 above the laser room so the laser hits the first receiver. Travel back to the future and place a portal on the small wall in the laser room to shoot at the receiver. Return to the present; the laser should still be hitting the first receiver, powering up an elevating platform. Stand on the platform and shoot a time portal behind the node to raise the platform further, allowing you to summon a reflector cube. Place this reflector cube on the small lip above the second receiver. Travel into the future. Pick up the future reflector cube and run into the laser room. Place another time portal in the laser room to bring the future reflector cube into the present. Position it to reflect the laser to the second receiver through the node. Now, get to the other side of the particle field without going through it (use a portal or time portal). You need to be in the present on the other side. 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 chamber.
