Schizm Hints

What am I supposed to do with the two machines inside the tunnel?

  • 1 of 25: There are two machines located inside the tunnel.  They are opposite each other, and are identical (both in appearance, and in how they work).
  • 2 of 25: The machines are going to be used to send gas to an airship located elsewhere.  Your job is to find the correct gas to mobilize the airship.
  • 3 of 25: Look around you -- not only at the machine against the wall.
  • 4 of 25: Notice the button in the middle, and the arrow located on that button.
  • 5 of 25: What happens when you press that button?
  • 6 of 25: Have you activated any of the 10 levers before pressing the button?
  • 7 of 25: Notice what happens on the adjacent meter after you press the center button.
  • 8 of 25: Pressing the center button lets you read the meter that's to the side of the levers.  The meter is reading the amount of gas that you dispensed when you pressed the levers.
  • 9 of 25: You should have encountered an apparition of Dr. Bremmer, somewhere in the vicinity of the machines, who will give you a clue as to what you need to do.  The image appears randomly, so it's not always possible to see the image right away.
  • 10 of 25: Dr. Bremmer said "One gas ... two times stronger than the others..."
  • 11 of 25: Each lever dispenses a different gas.  All are the same strength, except one -- which is twice the strength of the others.
  • 12 of 25: You'll need to determine which lever corresponds to the stronger gas.  Only the stronger gas will properly inflate the airship.
  • 13 of 25: After you read the meter, you only get one chance to press the correct lever -- the lever you press *now* (i.e., after reading the meter) determine which gas fills the airship.  (The levers you pressed before reading the meter only fill up the meter itself, and not the airship.)  The machine resets to a new value each time you try to inflate the airship and each time you leave the puzzle and reapproach it!   This means that a different lever will produce the stronger gas each time you try this puzzle.
  • 14 of 25: If you pressed each lever once, then pushed the arrow button in the center and read the meter, the meter would have counted 11 units of gas -- nine that are regular strength and one that is double, or 9+2=11.  But that doesn't tell you which specific lever dispensed the stronger gas.
  • 15 of 25: How can you determine, with only one reading, which of the ten levers releases the stronger gas?
  • 16 of 25: You need to find a pattern in how your press the 10 levers to help you uniquely identify each of the 10 levers.
  • 17 of 25: Dispensing a different amount of gas from each lever should help.
  • 18 of 25: After approaching the machine, start with any one of the levers, and click it once.  Then click the next lever (working in a pattern, such as clockwise) twice, to dispense that gas twice.  Move to the third lever, and click it three times, and so on.
  • 19 of 25: When you have done this with all ten levers, click the center button to read the meter.  What will the meter tell you?
  • 20 of 25: If you add up how many times you have pushed each of the ten levers, you will find that you've pushed the levers a total of 55 times (1+2+3+4+5+6+7+8+9+10). 
  • 21 of 25: However, that won't be your result on the meter.  Remember, one gas is twice as strong -- so you'll have an answer greater than 55.
  • 22 of 25: Since you made a total of 55 pushes, and only one of the ten paddles dispenses a double dose of gas, the difference between what the meter reads and 55 will tell you which lever dispenses the double dose of gas.
  • 23 of 25: If, for example, the meter reads 63, subtract 55 from that number to get 8.  So in that example, we know that the gas that is twice as strong was dispensed by the lever that was pushed 8 times -- and the 8th lever is therefore the correct one to push.
  • 24 of 25: Turn back to the gas collector, and press the correct lever once.  You should see a cut scene of the airship beginning to rise.
  • 25 of 25: You will now need to release the other half of the gas needed for the airship by performing the same steps on the second gas collector (directly behind you).
