Understanding the Level Layout


Before you begin playing Chapter 7 of Portal 2, it is important to understand the layout of the level. This will give you a better idea of what to expect and help you navigate through the puzzles more efficiently. In this guide, we will break down the different areas of the level so you can be fully prepared for what lies ahead.

Main Chamber

The main chamber of Chapter 7 is where you first start off. This area is quite large and contains multiple platforms, staircases, and a variety of buttons and switches. You’ll need to use these different elements to navigate your way through the level and eventually reach the exit. It’s important to take your time to explore the different areas of the main chamber as you may find hidden items that can be useful later on.

Wheatley’s Lair

This area of the level is where you’ll encounter Wheatley, the robotic personality core. Wheatley’s lair consists of various rooms and corridors that are filled with obstacles and hazards. You’ll need to use your puzzle-solving skills to get through this area in one piece. Be prepared to jump over obstacles, dodge lasers, and use your portal gun to create new pathways.

Final Chamber

The final chamber is where you’ll face off against GLaDOS, the main antagonist of Portal 2. This area includes a series of challenging puzzles that require fast reactions and quick thinking. It’s important to take your time and carefully plan out each move as one wrong step could mean instant death. Be sure to use your portal gun wisely and remember that timing is key.


By understanding the layout of Chapter 7, you’ll be able to navigate through the level more efficiently and effectively. Remember to take your time and explore each area thoroughly. With a little patience and some clever puzzle-solving skills, you’ll be able to triumph over GLaDOS and complete the chapter in no time!

Analyzing the Puzzle Mechanics

The Reunion contains some challenging puzzle mechanics that require careful observation and strategic thinking. The most prominent puzzle mechanics in this chapter are:

  • The Excursion Funnel
  • The Thermal Discouragement Beam
  • The Aerial Faith Plate

The Excursion Funnel allows players to move through the air and control their trajectory. Learning to use the velocity generated by the funnel to reach specific areas is critical to solving some of the puzzles in this chapter.

The Thermal Discouragement Beam is a laser beam that deflects off of certain surfaces and destroys certain objects, such as turrets or cubes. There are several puzzles that require players to use the laser beam in creative ways to solve them.

The Aerial Faith Plate is a device that launches players into the air. It’s essential in some puzzles where players need to reach high platforms to proceed. However, it can be tough to control the landing, making players vulnerable to falling into hazards or missing the target.

Understanding how all these puzzle mechanics interact and working out how to use them together is essential to completing The Reunion puzzles. Keep practicing and experimenting to master these mechanics, and you will eventually overcome these challenging puzzles.

Solving the First Half of the Level

The Reunion is one of the most challenging levels in Portal 2, but with some patience and practice, you can easily master it. The first half of the level consists of a series of puzzles that require careful planning and precise timing.

The First Puzzle:

The first puzzle involves redirecting lasers using cubes and portals. You will need to use your cube to block the laser, and then redirect it to hit the receptor. Keep in mind that the laser can only pass through portals, not cubes.

Tip: Look for the white wall where you can shoot your portals. This wall is located next to the laser emitter. Also, remember that you can carry the cubes across the orange goo without falling.

The Second Puzzle:

The second puzzle requires you to use two cubes to activate two buttons simultaneously. To do this, place one cube on the button and use the other cube to redirect the laser towards the second button.

  • Place one cube on the button
  • Use portals to collect the other cube
  • Use the second cube to block the laser and redirect it to the second button

Tip: Use your portals to transport the cubes and avoid the orange goo. Also, make sure to time your movements carefully to avoid getting hit by the laser.

Mastering the Second Half of the Level

After successfully navigating through the first half of Chapter 7, it’s time to focus on the second half. Here are some tips to help you master it:

  • Utilize the Tractor Beam: In the second half of the level, you will need to use the tractor beam to move cubes and turrets around. Make sure to fully understand how the tractor beam works and how to control it properly.
  • Position the Turrets Carefully: When using the tractor beam to move turrets, make sure to position them in a way that they won’t block your path later on. You don’t want to accidentally walk into the line of fire.
  • Use the Aerial Faith Plate: Once you have moved the turrets out of the way, use the aerial faith plate to launch yourself across the gap. Make sure to time your jump properly so you don’t end up falling into the toxic goo.
  • Watch out for the Crushers: The second half of Chapter 7 also features some crushers that can crush you if you’re not careful. Make sure to keep an eye out for their timing and move quickly to avoid them.
  • Take Advantage of the Excursion Funnels: The excursion funnels in this level can be extremely helpful in navigating past obstacles and reaching new areas. Make sure to experiment with them to see how they can help you.

By following these tips and mastering the second half of the level, you’ll be well on your way to completing Chapter 7 of Portal 2. Good luck!
