Chamber 7: Progress Barriers

First up, you're in the main room. See that block? Push it down through the hard light barrier. Follow it all the way to the bottom floor. Keep an eye out for the teleporter beneath the '1' on the wall – don't fall in! Now, push that block onto the floor switch on the right. This will open all the doors marked with a '2'.

Head up the left side until you can jump across to the door on the right, the one with the '2' next to it. Step inside. You'll see these moving squares casting shadows on your left, and switches above you to control them. This is the tricky part. You need to time your switch presses to cover about 95% of the floor in shadow. Here's the breakdown: Press the first switch when the lowest square's shadow hits the left side. Then, hit the top-left switch when the middle square's shadow is just under the right security camera, covering the right side. Finally, stop the top square when it's directly under the middle camera, casting a shadow straight down.

Once the floor is sufficiently shadowed, hop through the teleporter. Cross over to the other side, run to the terminal, and hack it. After that, head back down to the central room where you left the block. Push this block over to the far-left switch. Now, jump over the single teleporter on the ground and enter the right-hand entrance.

In this new area, jump over the floor teleporters to reach the block. Your mission here is to guide this block through a series of teleporters. Start by pushing it into the first one. Follow it through. Next, push it into the subsequent teleporter, but be careful to fall straight down. Then, push the block into the teleporter on the left, followed by the one on the right, and finally, guide it into the teleporters on the wall.

You'll reappear in the main central room. Push the block onto the lonely teleporter right there. Jump across to the other side and push the block through to the final room containing the terminal. Once the block is sitting on the floor switch, jump up. Oh, and if you haven't grabbed the **[Helix]** yet, now's the time! It's super easy to find in this area.

With the terminal hacked, drop down, then drop down again to the block on the floor switch. Reset the block onto the middle switch. Now, rescale the tall room and exit through the door. You've done it!
