  18. 18
    Go down the stairs, past the explosive barrel, and through the next door into 707 Factory Sewer.
  19. 19
    In the sewer, face either two Hunter Betas or seven Worms.
  20. 20
    Jump into the waterway, move right, then head for an alcove on the left wall and climb to dry ground. Follow the hallway to the next door.

    Behind the cabinet, stand in front of the testing machine on the far left and use the WATER SAMPLE to start the water testing puzzle.
  28. 28
    The puzzle requires adjusting A, B, and C wave ranges to match the water sample's total range. Adjust the red, yellow, and blue cells so their combined column height matches the white columns.
  29. 29
    Example Solution for COMBINATION 1: A: Left once, B: Left twice, C: Right twice.

    Example Solution for COMBINATION 2: A: Right once, B: Right 3x, C: Left 4x.
