0x10c

0x10c is an unreleased game that was being developed by Notch and Mojang during 2012 and 2013 as a followup to Minecraft. It has since been cancelled, and at present it seems unlikely that Notch, or anyone currently working at Mojang, will resume its development.

"0x" is a prefix used in several programming languages, to indicate a hexadecimal number. "0x10c" (ten to the C power) is a hexadecimal number equivalent to 1612 in decimal, which equals 281,474,976,710,656, which was the number of years that had passed since 1988 in the game's story.

Announcement
In March 2011, Notch was asked in an interview if Mojang had any plans for another game, and Notch expressed his desire to create an "extremely nerdy" space trading simulator. Later, in December 2011, Notch announced he would be stepping down as lead developer of Minecraft, and that he would begin working on another project. Carl Manneh said in an interview with Edge Online that Mojang was committed to supporting a new project that Notch was developing. In March 2012, he revealed that there were three different projects he was working on, but he had yet to decide which one he was committed to. On March 13th, he announced he would begin prototyping a space game, and on March 21st, in an interview with PC Gamer magazine, he announced that he was working on a space-themed game that was inspired by the television show Firefly and the video game Elite.

On April Fools' Day 2012, instead of a typical Minecraft April Fools joke, as was the case the prior year and every year since, Mojang launched a satirical website for a space game entitled Mars Effect, citing a lawsuit with Bethesda regarding the title of the Mojang game Scrolls as an inspiration. However, the gameplay elements remained true, and on April 4, 2012, Mojang revealed it as an actual space sandbox title, ''0x10c.

The game's backstory, as told by Notch on the website, was this:

The game was to feature:
 * Hard science fiction
 * Lots of engineering
 * Fully working computer system
 * Space battles against the AI or other players
 * Abandoned ships full of loot
 * Duct tape
 * Seamlessly landing on planets
 * Advanced economy system
 * Random encounters
 * Mining, trading, and looting
 * Single and multi player connected via the multiverse

Of particular interest was the in-game computer, the DCPU-16. This was a fully functioning emulated 16 bit CPU that could be used to control your entire ship, or just to play games on while waiting for a large mining operation to finish. Full specifications of the CPU were released soon after the game's announcement, so the more programatically advanced of the playerbase could get a head start. These specifications, along with the specifications for several pieces of in-game hardware that would have been able to interface with the DCPU-16, can be found here.

Development
Soon after the announcement of 0x10c, Notch began posting on Twitter about his plans for the game, and began putting images of the prototype versions on his website. A forums, subreddit , wiki , and numerous other fan-made websites were created, and Notch began communicating with fans about the game on the subreddit as well.

On April 16, 2012, Notch posted an image on the 0x10c website containing a puzzle. When decoded, it revealed the word “Montauk”, which was the password to get into another page on the website, which contained 99 codes which could each be redeemed once on the Mojang website to add 0x10c to the user’s Mojang account, which would have allowed them to play it as soon as the game was eventually released. 0x10c remained part of these user’s Mojang accounts until it was eventually removed from the Mojang account system in 2020.

On May 2, 2012, Notch launched an ARG to promote the game. A secret page on the 0x10c website read “insufficient power” along with a power percentage. The more people visited this page, the higher the power percentage became until eventually reaching 100%, whereupon a large amount of garbled code was revealed, which the community determined represented radio signals from a pulsar. Discrepancies in the repeating pulsar signals were eventually decoded and revealed to be garbled text taken from Isaac Asimov’s short story The Last Question, which, like 0x10c, also takes place in the extremely distant future of the universe.

Notch later began livestreaming himself coding 0x10c on Twitch. One of the results of this was viewers were able to copy significant amounts of the code and create a reverse-engineered version of the game. Notch asked that this not be publicly released, as the game was not yet close to a state he felt comfortable releasing. However, a prototype version of the game was accidentally leaked anyway, when Notch uploaded it to a private page on his website but forgot to disallow users from viewing all the site's files. This prototype, featuring a dark room with a computer, can be found here.

Originally, Notch intended for the art style of 0x10c to be mostly textureless, citing the 1993 game Frontier as inspiration. However, he later changed his mind, and Jonatan Pöljö, also known as Eldrone, was hired as an artist for the game, and created most of the textures and models seen in the later footage. According to Eldrone:

Progress continued, and eventually Notch released several videos on Youtube and the 0x10c website showcasing the progress he had made,  Including two physics test videos, an art test video and a multiplayer test video. Eventually, a semi-playable version, featuring a fully modeled and textured spacecraft with an interior and exterior, functional multiplayer and PVP, and the basics of the in-game computer systems, was created, and Notch livestreamed himself battling other Mojang employees onboard the ship.

Later, Eldrone released a "Facebuilder" demo as a preview of the game's player customization system, created in Unity. This can be found here.

0x10c was planned to require its players to pay a monthly subscription fee in order to access the global multiplayer server that was planned to exist, due to the computational cost of simulating the trajectories and onboard systems of all the player's ships, even when the players piloting those ships weren't logged in. A recurring fee would not have been required to play singleplayer, and it's likely there would have been the option to play on smaller, privately hosted servers for free, as in Minecraft. The initial cost of buying the game was planned to start out small and increase as the game was developed, similarly to how Minecraft's price increased during the first few years of its development.

Cancellation
0x10c was eventually put on hold in April of 2013 because Notch had found creative blocks. However, at the time, he was still interested in expanding the development staff to push the game toward release.

Eventually, on August 13, 2013, Notch announced in a Team Fortress 2 livestream that 0x10c was indefinitely shelved, but Notch added that it could be made in the future if another Mojang employee was interested in developing it.

On August 19th, Notch wrote on his blog "The Word of Notch" about his reasons for the game's cancellation:

He then expressed his desire to not become "another under delivering visionary game developer", and said he would instead focus on making "smaller games that can fail" in the future. Regarding 0x10c, he said that "I want to play this game so much, but I am not the right person to make it. Not any more. I’m convinced a new team with less public interest can make a vastly superior game than what I would make."

On September 15, 2014, following Mojang's acquisition by Microsoft and Notch's departure from the company, the soundtrack for 0x10c was released by Daniel Rosenfeld. . He stated:

Eldrone would later release images of additional art assets created for 0x10c on his twitter and website.

Mentioned features
Many specific features were mentioned as being planned for 0x10c. These include:

Mentioned on the website

 * Generators. Each ship would have a generator capable of producing a fixed wattage, and everything you would connect to it would drain wattage.
 * Cloaking fields. These would have required almost all the power from the generator, forcing you to turn off all computers and dim all lights in order to successfully cloak.
 * The DCPU-16: a fully functioning emulated 16 bit CPU that could be used to control your entire ship, or just to play games on while waiting for a large mining operation to finish.
 * Clocks.
 * 1.44 megabyte 3½ inch floppy discs and floppy drives.
 * Keyboards.
 * The LEM1802 (Low Energy Monitor): a 128x96 pixel 16-color CRT monitor.
 * The SPC2000 (Suspension Chamber): a deep sleep cell containing a ZEF882 Time Dilation Field Generator.
 * The SPED-3 (Suspended Particle Exciter Display): a device that creates line-based holographic images.

Mentioned in interviews

 * Cooling systems and fires.
 * Crashing into planets and having to scavenge for parts to repair your ship.
 * Landing gear, which may break if a ship lands too hard.
 * Crashing into asteroids would damage onboard systems.
 * Devices could be overclocked, which may cause them to catch fire.
 * You would be able to use other people’s programs on your ship’s computer by using floppy discs.
 * Gravity generators. When a ship’s gravity generator is unpowered, objects inside the ship would be subject to the same physical forces as the ship itself.
 * Wires and other attachments that hang from the ceiling.
 * Automated turrets.
 * Refrigerators.
 * Laser guns.
 * A ship editor. Players would first build the external part, and then go into a room mode with a cutaway view of the ship, in which players would be able to carve out rooms with custom dimensions.
 * Specialized rooms such as medical bays.
 * Hull breaches, which would cause air to leak out.
 * A monthly subscription fee would have been required to access a global multiplayer server called the multiverse, due to the computational cost of simulating the trajectories and computers of all the player's ships, even when the players piloting those ships weren't logged in.
 * Each player would only be able to have one generator at a time, but multiple players would be able to place their generators on a single ship to give it more power, encouraging cooperation between players.
 * Sensors.
 * 3D printers.
 * Devices would have their own inventory, into which interior components could be placed. The devices themselves would be craftable from various materials using 3D printers, but the interior components would have to be scavenged from abandoned ships. Each of these components would come in many variants with different attributes.
 * Mining for gold and other metals. Terrain was not planned to be modifiable, in order to reduce world file sizes.
 * A leveling system in which players would level up in specialized skills. Dying would reset the player’s levels.
 * Players would keep their ships after respawning.
 * VR support.
 * Wires running electricity from the generator to other devices.

Mentioned on reddit

 * Lighting was planned to be more complex than in minecraft, which was because Minecraft focused on many blocks and polygons that could all change at any time, whereas 0x10c focused on modern lighting with very few polygons that rarely changed. For example, computer monitors would illuminate their surroundings with the same colors being displayed on the screen.
 * Asteroids and planets were “icosahedrons (20 sided dice) fed to a make-surface-from-arbitrary-triangle-mesh code that subdivides, colorizes and offsets the polygons based off various parameters tweaked per body type”. There may also have been “orbitals and halo worlds” with planetary terrain on their interiors.
 * Space was to be very dark, with most surviving stars being fairly dim and small. Ships would have sometimes gone dark for various reasons such as power failures, technical problems, and trying to avoid visual detection through windows.
 * Players would have been able to map controller inputs to ingame hardware.
 * Batteries, which would store power produced by generators.
 * Generators would not have required fuel.
 * Rotation-produced artificial gravity would have been possible, as well as using magnetic boots to walk on surfaces in zero-gravity.
 * Spacecraft would be “smaller than the nostromo, larger than a tie fighter.”
 * Smaller ships could be docked inside of and launched from larger ships.
 * The DCPU-16 would still function while on fire, but slower and with the RAM changing randomly.
 * Robots.
 * Food and mess halls. Oxygen would “magically last forever”, unless there was a hull breach.
 * There would be a player-driven economy system, and building ships and space stations would cost resources. Singleplayer would have optional cheats.
 * Planets would be big enough that 32 players on a planet would “pretty much never see each other”
 * Generators would explode when destroyed. Weapons would consume power or ammunition when fired.
 * Doors into space could be opened to put out fires. If doors stopped working, you would need to manually open them by either using blowtorch or hacking into them.
 * Things such as guns, refrigerators, computers, and shield generators would have an inventory with specific slots. Rifles and fridges, for example, would both be able to use cooling units, so players would have to choose whether to put their “titanium extravagant alien cooling unit” in their fridge to save generator power, or in their gauss sniper rifle to save cooldown time.
 * Laser guns, which would cause the target to heat up before taking damage.
 * If your generator was intact, you would be able to respawn in a sleep chamber powered by the generator. If your generator wasn't intact, a friend would need to revive you, or you would have to wait for everyone to die to respawn the ship.
 * Clicking a keyboard or a monitor would lock input, turn your view towards the connected monitor, and slightly zoom in. Escape would exit.
 * The ingame computers would crash if their interrupt queue was overflowed, if a specific undocumented code was called, or if the box was physically harmed. When it crashed, it would go into a state where sequential areas of ram would get overwritten with random noise, and the opcodes would take a lot longer to process. Since the monitor was memory mapped, it would blindly display this garbage data.
 * The game and the ingame computers would both run at 60 ticks per second.
 * Music would take a long time to build up, and there would be a lot of ambient sound effects.
 * Private multiplayer servers would be free to use, have IP-based and LAN options, and could be run on older versions.
 * The number of stars would be “large enough to feel large, but small enough so that players could map them all if they wanted to.”
 * Star positions would be static, but planets would orbit and spin.
 * While inside a ship, players would always be oriented upright, even in zero-gravity. Outside ships, players would be able to rotate freely in any direction.
 * Everything’s position would be measured relative to the center of the player’s current ship, with the rest of the universe moving around it from the ship’s point of view.
 * Using the ship editor, you would be able to make convex rooms with 45 degree walls, to keep it simple to use, and to encourage the use of multiple rooms. Rooms could have variable height and be placed on different heights.
 * The ship editor would create a more or less empty frame of a ship, and you would then have to place panels and other things manually in the actual game.

Trivia

 * According to Notch, the game’s name was “intentionally bad” as a marketing experiment to see if Mojang could get away with naming their next game “pretty much anything”.
 * “Mackapar Media”, a fictional company that produced some of the in-game hardware, was the company credited on Mojang's Pig Tales website, and is also mentioned in a video advertising the original Lego Minecraft set.
 * Another word for the number represented by the hexadecimal value “0x10c” is “Trillek”.
