#Portal 1 test chamber 18 series#

This testchamber's not over, yet! In the next room, note a pair of lift platforms that'll carry you to a pair of side rooms that overlook the main room with the bouncing energy pellet. At your leisure, pass through an orange portal to reach the room at the end of the moving platform hall. Step through the portal, onto the platform, and quickly look right to fire a blue portal into the room at the end of the hall. Allow the moving platform to move you back to the main room where you can again peek through the orange portal and wait for another moving platform. Immediately look left and fire your blue portal onto the wall at the end of the hall, again just below the arrow that points around the blind corner. Quickly warp through the portals to stand on the incoming platform. Place an orange portal on a nearby wall and peek through to spot an incoming moving platform. Look down the hall and fire a blue portal onto the wall, directly below the arrow that points around the corner.

#Portal 1 test chamber 18 series#

To the right is a long hall with a series of moving platforms that are now activated by the energy pellet receptor you just triggered. Perform a momentum jump just like before to jump back over the barrier in the center of the room. Through this miraculous series of events, the energy pellet will be guided into the pellet receptor at the other end of the room. The energy pellet will bounce off of the angled wall panel to the left, ricochet into the blue portal, come out the orange portal and then ricochet off of the angled wall panel on the right. Now place the orange portal on the black pock mark we mentioned earlier-it should be directly opposite the blue portal. Since that sentence obviously makes no sense, check out the screenshots we've taken. On the wall to the right, place a blue portal on the same spot of the opposite wall. First, note the black pock mark on the wall to the left that represents the second bounce of the energy pellet. This next portion of the room has a couple of angled wall panels, one of which is currently deflected the high energy pellet that bounces across the long room. The momentum will launch you over the barrier. Drop through the orange portal to fall out of the blue portal above, then guide yourself back into the orange portal as you fall. Simply launch a blue portal onto the wall panel far overhead, then place an orange portal on the ground beneath it. You'll use another momentum jump to get over the barrier, but this one is much simpler than the jump you just made. Once over the barrier, you're met with another barrier and a large incandescent particle field. You'll warp again to the blue portal placed on the wall panel and, with your increased momentum, will have the energy need to launch over the barrier. As you fall towards the ground just in front of the incandescent particle field, fire another orange portal on the ground directly below you. However, this momentum alone is not enough to get you over the barrier. Drop into the pit and into the portal to build momentum that'll carry through as you launch out the blue portal you placed earlier. In the side room is a small pit into which you can fire an orange portal. Look for a set of stairs along the left wall that lead to a side room. The floor directly below that wall panel will not take an orange portal, so you'll need to find somewhere else to build momentum. First, place a blue portal on the wall panel that's jutting out near the ceiling. Here you'll need to make another momentum jump to get through the incandescent particle field at the far end of the room. The receptor activates a platform in the room that'll take you to a third part of the testchamber. The pellet should warp through the wall and come out of the ceiling the enter the receptor. Place the blue portal on the ceiling above the pellet receptor, using the faint red light as a guide for the placement. Quickly pass through the incandescent particle field to stand next to the receptor and fire an orange portal onto the black mark on the wall that shows where the energy pellet hits. Wait for the energy pellet to warp its way to the half of the room with the pellet receptor. The placement of the blue portal should warp the high energy pellet and send it through the incandescent particle field that houses the pellet receptor. With the first portal placed, shoot a blue portal onto the same wall, five tiles over (to the left). First, fire an orange portal onto the wall that the energy pellet is bouncing against (place the portal directly on top of the black mark on the wall). Continue into the next portion of the testchamber where you'll find two incandescent particle fields that separate a high energy pellet dispenser and the pellet receptor.
