  def central_corridor()
    puts <<-CENTRAL_DESCRIPTION
    The Gothons of Planet Percal #25 have invaded your ship and destroyed
    your entire crew.  You are the last surviving member and your last
    mission is to get the neutron destruct bomb from the Weapons Armory,
    put it in the bridge, and blow the ship up after getting into an
    escape pod. 

    You're running down the central corridor to the Weapons Armory when
    a Gothon jumps out, red scaly skin, dark grimy teeth, and evil clown costume
    flowing around his hate filled body. He's blocking the door to the
    Armory and about to pull a weapon to blast you.
    CENTRAL_DESCRIPTION
    prompt()
    action = gets.chomp()

    if action == "shoot"
      puts <<-SHOT_DOWN
      Quick on the draw you yank out your blaster and fire it at the Gothon.
      His clown costume is flowing and moving around his body, which throws
      off your aim.  Your laser hits his costume but misses him entirely.  This
      completely ruins his brand new costume his mother bought him, which
      makes him fly into an insane rage and blast you repeatedly in the face until
      you are dead. Then he eats you.
      SHOT_DOWN
      return :death

    elsif action == "dodge"
      puts <<-STOMPED
      Like a world class boxer you dodge, weave, slip and slide right
      as the Gothon's blaster cranks a laser past your head.
      In the middle of your artful dodge your foot slips and you
      bang your head on the metal wall and pass out.
      You wake up shortly after only to die as the Gothon stomps on
      your head and eats you.
      STOMPED
      return :death

    elsif action == "tell a joke"
      puts <<-JOKEY
      Lucky for you they made you learn Gothon insults in the academy.
      You tell the one Gothon joke you know:
      Lbhe zbgure vf fb sng, jura fur fvgf nebhaq gur ubhfr, fur fvgf nebhaq gur ubhfr.
      The Gothon stops, tries not to laugh, then busts out laughing and can't move.
      While he's laughing you run up and shoot him square in the head
      putting him down, then jump through the Weapon Armory door.
      JOKEY
      return :laser_armory

    else
      puts "DOES NOT COMPUTE!"

  end

  def laser_armory()
    puts <<-LASER_DESCRIPTION
    You do a dive roll into the Weapon Armory, crouch and scan the room
    for more Gothons that might be hiding.  It's dead quiet, too quiet.
    You stand up and run to the far side of the room and find the
    neutron bomb in its container.  There's a keypad lock on the box
    and you need the code to get the bomb out.  If you get the code
    wrong 10 times then the lock closes forever and you can't
    get the bomb.  The code is 3 digits.
    LASER_DESCRIPTION
    code = "%s%s%s" % [rand(9)+1, rand(9)+1, rand(9)+1]
    print "[keypad]> "
    guess = gets.chomp()
    guesses = 0

    if guess == "reset"
      puts <<-RESET_DESCRIPTION
      You hear a soft click as the neutron bomb's container
      opens, revealing the bomb inside. You're not quite sure
      how you did it, but you just hacked the Gibson.
      RESET_DESCRIPTION
      return :bridge_access

      while guess != code and guesses < 10

        print "[keypad]> "
        guess = gets.chomp()
      end
    end

    if guess == code
      puts <<-CODE_DESCRIPTION
      The container clicks open and the seal breaks, releasing a cloud of gas.
      You grab the neutron bomb and run as fast as you can to the
      bridge where you must place the bomb in the right spot.
      CODE_DESCRIPTION
      return :bridge_access
    else
      puts <<-FAILURE_DESCRIPTION
      The lock buzzes one last time and then you hear a sickening
      melting sound as the mechanism is fused together.
      You decide to sit there, and finally the Gothons blow up the
      ship from their ship and you die.
      FAILURE_DESCRIPTION
      return :death
    end
  end

  def bridge_access()
    puts <<-BRIDGE_ACCESS
    You round the corner, ready to make your way to the bridge and to the escape
    pods that lie beyond. Unfortunately, you see a huge pile of debris blocking 
    your way. Luckily, you can see a panel that covers a maintenance tunnel is
    slightly askew. The tunnel appears to be unoccupied, but you can never tell
    with Gothons. You could also try to make your way over the pile of debris.
    Or you could wait here for the cleaning service to come and clear the trash
    out of your way.
    BRIDGE_ACCESS
    prompt()
    action = gets.chomp()

    if action == "enter tunnel"
      puts <<-TUNNEL_DESCRIPTION
      The access tunnel is dark, but you manage to make your way through. 
      Luckily, it seems those unsettling noises were just the ship coming
      apart, and not a hungry alien in a hideous clown costume ready to
      leap out and tear you to shreds.
      TUNNEL_DESCRIPTION
      return :the_bridge

    elsif action == "climb debris"
      puts <<-DEBRIS_DESCRIPTION
      You bravely begin to climb the mountain of rubble, but about halfway
      up, you slip and fall. You narrowly miss impaling yourself on a bit of
      rebar. Breathing a sigh of relief, you realize you've got bigger problems.
      The rubble shifts beneath you, effectively crushing your lower body.
      You've got no choice but to wait for the sweet release of death.
      DEBRIS_DESCRIPTION
      return :death

    elsif action == "wait here"
      puts <<-WAIT_DESCRIPTION
      You realize I was kidding, right?
      Leaning up against the wall, you wait for the cleaning crew to arrive.
      Fortunately, you don't have to wait long as a team of Gothons are along
      momentarily and blast you into vapor.
      WAIT_DESCRIPTION
      return :death

    else 
      puts "DOES NOT COMPUTE!"
      return :bridge_access
    end
  end

  def the_bridge()
    puts <<-BRIDGE_DESCRIPTION
    You burst onto the Bridge with the neutron destruction bomb
    under your arm and surprise 5 Gothons who are trying to
    take control of the ship. Each of them has an even uglier
    clown costume than the last. They haven't pulled their
    weapons out yet, as they see the active bomb under your
    arm and don't want to set it off.
    BRIDGE_DESCRIPTION
    prompt()
    action = gets.chomp()

    if action == "throw the bomb"
      puts <<-THROW_DESCRIPTION
      In a panic, you throw the bomb at the group of Gothons
      and make a leap for the door. Right as you drop it, a
      Gothon shoots you right in the back, killing you.
      As you die you see another Gothon frantically try to disarm
      the bomb. You die knowing they will probably blow up when
      it goes off.
      THROW_DESCRIPTION
      return :death

    elsif action == "slowly place the bomb"
      puts <<-PLACE_DESCRIPTION
      You point your blaster at the bomb under your arm
      and the Gothons put their hands up and start to sweat.
      You inch backward to the door, open and then carefully
      place the bomb on the floor, pointing your blaster at it.
      You then jump back through the door, punch the close button
      and blast the lock so the Gothons can't get out.
      Now that the bomb is placed, you run to the escape pod to
      get off this tin can.
      PLACE_DESCRIPTION
      return :escape_pod
    else 
      puts "DOES NOT COMPUTE!"
      return :the_bridge
    end
  end

  def escape_pod()
    puts <<-ESCAPE_POD_DESCRIPTION
    You rush through the ship desperately trying to make it to
    the escape pod before the whole ship explodes. It seems like
    hardly any Gothons are on the ship, so your run is clear of
    interference. You get to the chamber with the escape pods, and
    now need to pick one to take. Some of them could be damaged
    but you don't have time to look. There are 5 pods, which one
    do you take?
    ESCAPE_POD_DESCRIPTION
    good_pod = rand(5)+1
    print "[pod# #]>"
    guess = gets.chomp()

    if guess == "the correct pod"
      puts <<-CORRECT_DESCRIPTION
      Trusting to instinct, you hop into the pod directly across
      the room. Slamming the eject button as soon as the hatch closes,
      you quickly leave the ship behind. In the distance, you watch
      as it explodes into a fiery supernova. Thankfully, the blast
      is too far away to affect your escape pod.
      Congratulations! You won!
      CORRECT_DESCRIPTION
      Process.exit()
    elsif guess.to_i != good_pod
      puts  
      puts <<-BAD_POD
      "You jump into escape pod #{guess.to_i} and hit the eject button.
      The pod escapes out into the void of space, then
      implodes as the hull ruptures, crushing your body
      into a jelly."
      BAD_POD
      return :death
    else
      puts <<-GOOD_POD
      You jump into pod #{guess.to_i} and hit the eject button.
      The pod easily slides out into space, heading to
      the planet below. As it flies to the planet, you look
      back and see your ship implode, then explode like a
      bright star, taking out the Gothon ship at the same time.
      You won!"
