Getaway Vehicles

Test Chamber 13: Place portals as shown to redirect a laser with a time portal into the future. Travel through the time portal, then rearrange present portals to direct the laser into the target, allowing you to exit.

Test Chamber 14: Travel to the present and summon a reflector cube. Position it to redirect a laser through nodes. Travel to the future, use portals to bring a laser into the present through a time portal. Retrieve the future reflector cube, bring it to the present, and position it to hit all three nodes. Travel back to the future, then to the present. Position the future reflector cube to reflect the laser into the receiver to complete the chamber.

Test Chamber 15: Start by going through a 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 bypass the particle field. Return to the present using another time portal. Place a new portal on the upper wall to direct the laser to the first receiver. Travel to the future, place a portal on a small wall in the laser room to shoot the receiver. Return to the present. Use the elevating platform to reach a higher position. Place a time portal behind a 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, retrieve the future reflector cube, and bring it back to the present via a time portal in the laser room. Position it to reflect the laser through the node into the second receiver. To bypass the particle field, use a portal on the other side or a time portal. Reach 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. Finally, move the reflector cube onto the switch to complete the chamber.
