Swap

"Swap" is the fifteenth and last Test Chamber of Chapter 2 taking place in Test Track 09. It contains 2 Slimeballs and 3 Levers. The soundtrack playing in this chamber is "Final Concentration", the sixteenth song of the album.

## Description

This final chamber is split into a couple of sections that all need to be solved one after the other in the right order to grant access to the finish. As expected, it utilizes all Mechanics the Chapter has to offer as one united challenge.

## Solution

To start off, stand on the pressure plate to your left, then shoot at the now activated attraction pad on the platform in front. Step on the pressure plate there and shoot your arrow through the Death Field at the pad.

Go into the hallway to the right and enter the room to the left. Stand on the pressure plate and aim at the attraction pad on the ceiling and time the shoot so you'll land on the moving scaffold as it is travelling towards the left, then quickly turn around and shoot the pressure plate to prevent getting vaporized. Collect the lever from the chest and jump back down.

Next, go to the room on the opposite side of the hallway and place your lever on the wall. Wait for the countdown to finish and the doors to fully toggle, then destroy it again. Quickly shoot your arrow at the attraction pad on the ceiling on the right side before the door closes, then shoot over on the floor of the other side.

In this part of the outside are, shoot over to the opposite side out front, then turn around and shoot yourself to the top pad in front of you, then into the room up top, where you collect your Slimeball. Shoot your arrow at the bottom pad and then use it to disable the Death Field.

Make your way through the hallway and open the door at its end, then navigate the Attraction pads to the roofed pressure plate and press it down to open the door with your Slimeball. Return to the previous platform and shoot yourself to the pad above the now open door, where you collect your second Slimeball.

Make your way back along the pads and collect your Slimeball, then return towards the starting area. Drop your Slimeballs through the Death Field, then turn the roundabout and collect them from below to bring them past the Anti-Science Field. At the door below said particle field, use one of your Slimeballs to activate one of the pressure plates in the walls, and your arrow to activate the other. Go inside and retract your arrow and do the same with the next set of plates. Collect your Lever from the chest, take your Slimeballs and leave the room.

Use the togglable Attractor Pads to get to the hallway again, then make your way to the right room and follow the same procedure as before to get to the outside area. **WARNING!** As the sign warns you, pay attention to the Anti-Science Field around the corner and instead of losing your Slimeballs to it, shoot your arrow at the attraction pad on the opposite side. From there, turn around and shoot up to the top right ledge. There, use both your Slimeballs to open the door to collect your third lever. Recollect your Slimeballs and leave the area by shooting at the bottom pad and deactivating the Death Field with your arrow again.

Now, make your way to the end of the hallway and open the door with a lever and like before, navigate along the pads again and use Slimeball #2 to open the door, then make your way through the door and recollect the second Slimeball by pressing the button again. Use your two levers and two Slimeballs and your arrow to open the Exit Door. Chamber solved, Chapter complete!
