The beginning of chapter 7 has a Yellow Cube problem. First, pick up the Yellow Cube and use it to open the door. When the door opens you throw away the Yellow Cube, as it is no longer needed.

Move forward, go around the left side, and jump across three times. Pick up the Blue Cube, then jump back to the main area. Place the Blue Cube into the Blue Cube Slot. After that, grab the Green Cube, go through the tunnel, and place it into the Green Cube Slot.

Now return to the Blue Cube, pick it up again, and cross the bridge. Place the Blue Cube into the charging slot. Once it is charged, take it out and put it back into the Blue Cube Slot. Continue down the path until you reach a pedestal with a button.

Go down and scan the bridge. The scan shows that the bridge needs Seven Power Pips. To solve this, place the third Cube in the center. When the doors open, take the Cube and put it into the charging slot. After it charges, remove it and place it back in the center.

Next, go to the Branch Portal and activate a branch. Press the pedestals on the left end, then head upward. The bridge should now activate. Cross the bridge, go through the Portal, and continue up the path.
