You can only blow the whistle once the trophies are all collected.
I pocketed the whistle and opened the sack on the kitchen table. I saw a clove of garlic inside, and I added it to my inventory. Then I ran west, into the living room. The floor was covered with a large Oriental rug. Antique furniture, the kind I’d seen in films from the 1940s, was positioned around the room. A wooden door with odd characters carved into its surface was set into the west wall. And against the opposite wall there was a beautiful glass trophy case. It was empty. A battery-powered lantern sat on top of the case, and a shining sword was mounted on the wall directly above it.
I took the sword and the lantern, then rolled up the Oriental rug, uncovering the trapdoor I already knew was hidden underneath. I opened it, revealing a staircase that led down into a darkened cellar.
I turned on the lamp. As I descended the staircase, my sword began to glow.
I continued to refer to the Zork notes in my grail diary, which reminded me exactly how to make my way through the game’s labyrinth of rooms, passageways, and puzzles. I collected all nineteen of the game’s treasures as I went, returning repeatedly to the living room in the white house to place them in the trophy case, a few at a time. Along the way, I had to do battle with several NPCs: a troll, a Cyclops, and a really annoying thief. As for the legendary grue, lurking in the dark, waiting to dine on my flesh—I simply avoided him.
Aside from the Cap’n Crunch whistle hidden in the kitchen, I found no surprises or deviations from the original game. To solve this immersive three-dimensional version of Zork, I simply had to perform the exact same actions required to solve the original text-based game. By running at top speed and by never stopping to sightsee or second-guess myself, I managed to complete the game in twenty-two minutes.
Shortly after I collected the last of the game’s nineteen treasures, a tiny brass bauble, a notice flashed in my display informing me that the Vonnegut had arrived outside. The autopilot had just landed the ship in the field to the west of the white house. Its cloaking device was still engaged and its shields were up. If the Sixers were already here, in orbit around the planet, I was hoping they hadn’t spotted my ship.
I ran back to the living room of the white house one last time and placed the final treasure inside the trophy case. Just as in the original game, a map appeared inside the case, directing me to a hidden barrow that marked the end of the game. But I wasn’t concerned with the map or with finishing the game. All of the “trophies” were now “collected” in the case, so I took out the Cap’n Crunch whistle. It had three holes across the top, and I covered the third one to generate the 2600-hertz tone that had made this whistle famous in the annals of hacker history. Then I blew one clear, shrill note.
The whistle transformed into a small key, and my score on the scoreboard increased by 18,000 points.
I was back in second place, a mere 1,000 points ahead of Aech.
A second later, the entire Zork simulation reset itself. The nineteen items in the trophy case vanished, returning to their original locations, and the rest of the house and the game’s playing field returned to the same state in which I’d found them.
As I stared at the key in the palm of my hand, I felt a brief jolt of panic. The key was silver, not the milky green color of jade. But when I turned the key over and examined it more closely, I saw that it actually appeared to be wrapped in silver foil, like a stick of gum or a bar of chocolate. I carefully peeled the wrapper away, and a key made of polished green stone was revealed inside.
The Jade Key.
And just like the Copper Key, I saw that it had a clue etched into its surface:
Continue your quest by taking the test
I reread it several times, but had no immediate revelations as to its meaning, so I placed the key in my inventory, then examined the wrapper. It was silver foil on one side and white paper on the other. I didn’t see any markings on either side.
Just then, I heard the muffled roar of approaching spacecraft and knew it must be the Sixers. It sounded like they were here in force.
I pocketed the wrapper and ran out of the house. Overhead, thousands of Sixer gunships filled the sky like an angry swarm of metal wasps. The ships were separating into small groups as they descended, heading off in different directions, as if to blanket the entire surface of the planet.
