Roadbose

Template:Infobox Player Roadbose (also known as RoadMC2, GaMesFanTaSy, Roadkiller, TheRealZust, Super Pizza, or roadjunior) is a mysterious Korean player and hacker in Geometry Dash. He became famous for his hacked level ICE Carbon Diablo X and for creating brutally hard and impossible levels. He has been around since Update 1.3. He got the impression that he is hated, thus quit in early 1.9. Some people have impersonated him since then, but he still hates the game and has deleted everything on his Naver account. He returned to the game in early 2025 under the name roadjunior and began finishing some of his old unfinished levels.

Levels

Unrated levels

• Heaven And Hell - An infamous 1.4 former-impossible level that features several straight-flying sections and two-block-wide blue orb spam corridors. It used to have a secret way that was achievable by decent players. The level is still on the server but the secret way was removed due to the level being updated by a hacker. Seemingly random invisible objects were added as well, along with a ball timing being nerfed.
  • The player and creator KeiAs is the only person with a recording of a legitimate completion of the rated version of this level using the secret way.
  • The level was rated from January 2014 to somewhere between February 7, 2015 and April 4, 2015. The exact date of the unrate is not confirmed.
  • This level is a remake of hell and heaven by Pis.
  • This was one of the first levels to be deemed impossible.
    • The original rated version was beaten legitimately by Tuggy on July 12, 2021, and set a new record for the longest time between a level being published and beaten.
  • It is the oldest known level to include blue orb spam in the way that it was used in the level.
• ICE Carbon Chaos - The second level of the "ICE Carbon" series made in 1.5. The difficulty of this level is considered to be about the same as ICE Carbon Diablo X's. The level was previously deleted due to its poor reception and lack of recognition. It has now been restored from memory and reuploaded to the servers on March 22, 2025.

Hard levels

• Lightning Factory 2 (starred) - The third level in the "Lightning" series.

Harder levels

• Lets Go KOREA (starred) - Roadbose's first level. The level is fairly straightforward for its time but has some trolls that can throw the player off.

Insane levels

• LIGHTNING Jumper (featured) - The first level in the "Lightning" series.

Demon levels

Hard Demon levels

• Extreme super world (featured) - One of Roadbose's easiest Demons. Roadbose was working on an update for this level with 1.6 decoration but never finished it. The current version is the third version, updated in 1.8.
• Super Of Everything (featured) - A level made around 1.6. It is known for its insane memorization and timings. This was made semi-impossible in 2.1 due to portal physics changing, making the player die at 98%. This bug can be passed by turning off Smooth Fix or by setting the graphics to 1280x720.

Insane Demon levels

• ICE Carbon Diablo X (featured) - The third level in the "ICE Carbon" series. Formerly an Extreme Demon, it was originally placed #1 on the Demonlist and initially thought to be impossible because of its straight-flying and tight ship sequences. However, Riot eventually beat the level and said it was not as hard as Cataclysm. On September 28, 2017, it dropped out of the Demon List and entered the Legacy List.
  • The currently-rated and well-known version of ICE Carbon Diablo X is an updated version. A reupload of the very first version can be found on the profile of Compendium (PlayerID: 20417551) with the level ID 51079609.
• ICE Carbon Zust (starred) - The first level in the "ICE Carbon" series. It is a remake of Ice Hell Cave by Small. The level originally had a secret way at 46% that allowed the player to skip a chunk of the level, but after the creator's return in 2025, it was removed.

  • The video of unnerfed Silent clubstep does not have a single comment about that topic.
• In the comment section of the uploaded video of Extreme Super World on that channel, he claimed that he has beaten ICE Carbon Diablo X in 15,000 attempts. However, this turned out to be false, as the level was hacked.
• In 2019, someone recreated 2 of his levels (Back On Track S and Demon Cycles) on a private server name ZenosGDPS (this server is now shut down). The user hyper2149 (PlayerID: 89793882) reuploaded the levels on normal GD, and they are on iiiEvnosiii's account now.
