Trivia / Sonic Robo Blast 2

• Cut Song:
  • Mine Maze Zone, Rocky Mountain Zone, and Doomship Zone (among many other themes) still have their music buried within the game. The latter two eventually got remixes for the Tutorial Zone and Orbital Hangar Zone respectively.
  • The Pre-2.1 special stage music has become this with the advent of the NiGHTS-themed special stages in Version 2.1, but in version 2.2 it was remixed to become the music for the first special stage and reworked further into the other special stages.
  • Subverted with the originally-planned stage music for Arid Canyon Zone; it was re-used for the similarly-themed NiGHTS stage, and during 2.1 it was the only song used in these stages that was not from the Mystic Realm soundtrack. However, played straight with the 2.2 update.
  • More or less the entire original soundtrack became this with the 2.2 update, though most of these are in favor of new remixes. Cut nearly completely are the Mystic Realm tracks, except for Aerial Garden Zone and Prismatic Angel Zone (the latter used for the brutal bonus special stage Black Hole Zone), though they did return while buried in the game's music files.
• Development Hell: The Fangame.
  • SRB2 started out in 1998 as a TGF game, switched to Doom Legacy shortly after, and development still marches on 25 years later. To be fair, there have been long stretches of inactivity; the jump from 1.09.4 to 2.0 took four years, half of which was spent not making anything significant.
  • Version 2.1 was mired in Development Hell for almost as long, over a combination of real-life obligations and an insanely persistent, netgame-breaking bug that rendered the multiplayer modes almost unplayable. Fortunately, these issues that plagued the release for so long did eventually get fixed, with Version 2.1 finally releasing in March 2014.
  • Version 2.2. The five years it spent in development were used to completely redo most of the game and add many things that were previously thought impossible, especially in Doom Legacy. It's generally agreed that it was well worth the wait.
  • For further perspective: this game's development process is now older than Duke Nukem Forever, and there are probably community members on the message board that are younger than SRB2. (Eek.) That being said, at least it's been playable in some form for far, far less time, with a story that can be played from start to finish.
  • Even the people on the team can't help to take jabs at themselves, judging from this gem from the Red Volcano Act 2 comments section.

    D00D64: What you are looking at is the entirety of Red Volcano Act 2's progress. Expect the rest in another 8 years.

• Dummied Out:
  • Mine Maze Zone was planned to be a Dug Too Deep level before being merged into Arid Canyon.
  • Additionally, there are several beta rooms inside Egg Rock Zone Act 2 accessible only with the NOCLIP command.
  • The Chaos gametype was cut back in version 1.09; however, Chaos Enemy Spawns can still be placed, and it's possible to re-enable the (now half-broken) gametype with EXE modding.
  • Christmas and Adventure modes were removed in 2.0. The former caused lots of consistency errors in netgames, the latter was only a test and not particularly well-liked.
  • Some of the textures and flats from Zim's Base Zone still exist, too.
  • The original special stage music from Versions 2.0 and earlier has been replaced with songs from the Mystic Realm soundtrack for the new NiGHTS-themed special stages in Version 2.1, before being further updated into new arrangements of the special stage music used in both the single player NiGHTS special stages and the multiplayer platformer special stages. The original song is still in the game's files as an unused song, however.
  • The old version of Black Eggman that appeared in a scrapped version of Egg Rock Act 3 still exists as an object in the game.
  • There was originally plans for Egg Rock Zone to have its own standalone boss, but it was scrapped since people felt the endgame had enough bosses to fight as is. The boss itself later became a re-usable add-on for the base game.
• Promoted Fanboy: Two longtime developers (SSNTails and Spazzo) of SRB2 have gone on to monetize their hobby with Roly Poly Putt, an app for iOS. Some of the game's art and music might be a bit familiar, however...
