Sonic Robo Blast 2 is a fan-made Sonic the Hedgehog game based on a modified version of the Doom Legacy engine. Keep in mind that some of this content is in the game for modders to use. However, it's not used in the main, un-modded game, so here it goes.
|This page is showing its age.|
Please to fit our current standards! Here are some things you can do:
Still reflects Version 2.1 for the most part and hasn't been updated to reflect 2.2's significant changes.
- 1 Ultimate Mode
- 2 Unused Areas
- 3 Leftover Version 2.0 Map
- 4 Leftover Unused Cutscene
- 5 Unused Linedef Types
- 6 Unused Graphics
- 7 Unused Enemies
- 8 Unused Boss
- 9 Enemy Infighting
- 10 Unused Music
- 11 Unused Player Abilities
- 12 Development Mode
- 13 Unused Cutscenes
In Version 2.2.2, if the user types "ultimate" on the title screen (not as a command), One of four [Eggman Laughing] sound effects can be heared. This indicates that the player has toggled Ultimate Mode. The no file option in the "select game" menu will now be replaced with new graphics and the text that says "dont save!" is now replaced with "ultimate" in red. Ultimate Mode can also be accessed without using this cheat as an option in the speedrun-centric Marathon Run, added in 2.2.5.
Pressing enter on the no file option will give you a warning text before going to the character select.
During Ultimate Mode:
- The player starts with one life and no continues.
- All rings and ring monitors are removed.
- All shield monitors are removed.
- Extra life monitors will not give extra lives despite still being present in the game. When popped, they will instead play an error sound to indicate that they do nothing.
- Both types of Jetty-Syns (and any other Objects using
A_JetChase) will have doubled speed and fly higher above the target player.
- Both types of Buzzes (and any other objects using
A_BuzzFly) will be 1.25 times faster.
- All Objects using the actions
A_BrakFireSho]will have half the usual reaction time set afterwards.
Although this can only be accessed using cheats/a command line prompt, Ultimate Mode can be used as custom unlockable conditions for modding purposes.
All of these should be accompanied by pictures from a map editor, plus screenshots from the game if possible.
Jade Valley's leftover platforms
On Jade Valley Zone, there are two unused FOFs with Linedef Type 170 (
Crumbling, Respawn), one at a height of 664 FRACUNITs, tagged 9, and another at a height of 698 FRACUNITs, tagged 11. They are not tagged to any sector in the map, however...
|Version 1.09||Version 2.1 (Recreation)|
Both of those platforms exist in the Version 1.09 of the map; and by spawning them in Version 2.1 of the map, they have matching heights, confirming that they are leftovers!
Egg Rock 3's Unused Room
Right behind where the player starts, there is an unused room, containing a translucent FOF on the floor.
Flooded Cove's Hidden Room
Off to the side of the room with the breakable 128x128 cubes is a rather large inaccessible area with a tunnel. This tunnel leads to a hidden room with four 1-up Monitors and a big monolith with the BRAKCAT1 and BRAKCAT2 textures pasted on it. This was added as an Easter egg when the level was being decorated.
Leftover Version 2.0 Map
srb2.srb IWAD has the entirety of Green Flower Zone 1 from Version 2.0. It's replaced by the Version 2.1 variant after the
zones.dta PWAD is added at game startup.
Leftover Unused Cutscene
Also located in the
srb2.srb IWAD (specifically, in the
MAINCFG SOC lump) is a leftover secret Cutscene from Version 1.09.4, only activated if the date of the player's machine was on April 1st. Date-activated secrets were however removed as of Version 2.0, but not this Cutscene block.
The Cutscene itself is a recreation of the intro found in a earlier version of the game dating back to 1998, before making the move to the Doom Legacy engine. The graphics for it do not exist in the IWAD anymore, only its music, which is another unused asset.

Unused Linedef Types
Type 2 (Custom Exit)
This Linedef type can be tagged to a sector with with special type 8192 (
Exit/Special Stage Pit/Return Flag) to specify the next level after the tally screen. This is not found in any level in Version 2.1.
Type 4 (Speed Pad)
Turns the floor of the tagged sector into a speed pad which boosts the player's speed. This goes along with the similarly-unused sector types 1280 and 1536. This is not found in any level in Version 2.1.
Type 5 (Camera Scanner)
This temporarily changes the values of the camera distance, height and rotation as long as the player is in the sector with the effect. This is not found in any level in Version 2.1.
Type 65 (Bridge Thinker)
Does a great amount of nothing. The original purpose for this was to make pieces of a bridge move downwards when stood on (like in the Genesis Sonic games), but it didn't work properly when multiple players stood on it at once.
Types 386 to 396 (Old Slope Linedef types)
Those were linedef types present in maps used for slope debugging, still present in the game as of Version 2.1.20. Trying to use those will print a warning in the console, while loading the map:
WARNING: This level uses old slope specials.
A conversion will be needed before 2.2's release.
Types 700 to 715 (Slope Linedef types)
The supported slope specials as of Version 2.1.20. Those are not used in any vanilla maps and are available for modding.
Old Title Screen Assets
Although a brand new title screen was implemented, graphic files can still be found for the old title screen. interestingly, the only ones with actual sprites are TITLESKY and TTWING. TTBANNER, TTSONIC, TTSPOP*, TTSPREP*, TTSWAVE* and TTSWIP* are completely blank and comprise of only 13 bytes each. the sky can be seen again if you mod the game, or are waiting to join a server.
Options graphics that have gone unused after the menus or features belonging to them were changed or removed.
Also from the Options Menu, leftover older graphics for the sliders.
Screen and Message Box Borders
Used in message boxes for versions earlier than Version 2.1. Those were also as borders for the small viewport feature, removed in Version 2.0.
Given their lump names, and their black background, those might have meant to be used on the credits.
Brak Eggman Banner
Some rather mediocre textures depicting Brak Eggman, the final boss. These were used in the removed multiplayer map Zero Ring Zone.
ALL YOUR RINGS ARE BELONG TO US
Also from Zero Ring Zone, referencing this Internet meme.
This splotchy texture was originally used in Greenflower Zone before being replaced with the current checkerboard-style texture.
All of these enemies were used in the game at some point, even as recently as Version 2.0. They all became unused in Version 2.1.
It is surrounded by spikeballs and cannot be defeated by normal means, so it must be either avoided or attacked while invincible. When the player moves, it mirrors their forward and backwards movement, and stops when the player stops.
Brak Eggman (Version 2.0)
Thing Type 206 is the final boss from Version 2.0. This boss runs on a set pattern, cycling through three attacks: a steady stream of cannonballs, a sticky glue attack and a spread of missiles, and then he jumps to a random boss waypoint. The missiles he fires can be grabbed onto and redirected back into him to damage him, a scenario inspired by the Sonic OVA. The boss can also be damaged by jumping onto his head and then back off as he tries to swat the player away, causing him to damage himself. After five hits, the boss calls a Trigger Linedef event with tag 4200, originally used to destroy the central platform in the original arena.
This boss isn't actually that much bigger than the current Brak Eggman boss; his impressive stature in Version 2.0 was the result of a Level header setting that halves the size of all objects that aren't the boss.
Doom's monster infighting behavior is still functional here and enemies will attempt to fight back if damaged by another enemy's attack. However, there are no instances where this can be observed without object spawning commands; there are no enemies fought alongside bosses, and the only regular enemy that can survive a hit is the unused Crawla Commander.
A lot, many of which are leftovers from previous versions. Tracks that are likely to be in Version 2.2 are not listed.
|6 - Greenflower Zone Act 1 (Alternate)||Almost identical to the used song, but seems to combine backing instrumentation from Greenflower Zone Act 2.|
|9 - Deep Sea Zone Act 2 (Remix)||Rock remix of the DSZ2 theme.|
|12 - Boss Remix||Rock remix of the boss theme.|
|15 - Arid Canyon Remix||Remix of Arid Canyon's theme, with a rather long fade-in.|
|20 - MDK2 - Outer Space||Ominous space ambiance. This was originally intended for the space countdown rooms in Egg Rock.|
|21 - Doomship Zone||Scrapped level theme. A revival of this concept under the name Grand Eggship may eventually see the light of day; whether it will use this song or not is unknown.|
|27 - Egg Rock Zone Act 1 Premix (No Guitar)||Early version of ERZ1's theme which most notably lacks the cool guitar solo. Overall, this makes the song sound much closer to the original MIDI from which it was based on.|
|50 - Old/2.0 Era Special Stage||Used until Version 2.1, which replaced the old Special Stage maps with NiGHTS-style ones.|
|51 - Demo 4 Special Stage 1||This dates back to an even older version of the Special Stages. Note that the other Special Stage songs from this point of development have long since been removed. Why this one remains is a mystery.|
|94 - Zero Ring Zone||This Zero Wing-inspired song was used for a multiplayer map that lasted until v1.09.|
|96 - Mine Maze Zone Act 1||One of two early level concepts that became Arid Canyon.|
|97 - Arid Canyon Zone Act 2 Premix (No Lead)||The guitar version is also unused, but not for long!|
|98 - Old Aerial Garden Zone||A preliminary candidate for Aerial Garden's theme back when it was still part of the old level pack called Mystic Realm. It sounds more than a bit like Sky Sanctuary.|
|AK - The Final Countdown||Apparently will be used in a Zone for SRB1 Remake that currently isn't in the game yet.|
|EF - Evilflower Zone||A frequency-reversed version of an earlier arrangement of Greenflower Zone Act 1, hidden in srb2.srb unlike the rest of the game's music. No such zone existed and this track was most likely left for modders to use.|
Unused Player Abilities
Those are all available for modding, but unused in the vanilla game.
||Homing attack||A weakened version of the speed thok ability, but with the addition of a homing attack feature similar to that of Sonic Adventure and beyond – if an enemy, spring, or monitor is close enough to the player when triggering the ability, the player will home in towards the target object until they touch/destroy it. If the character fails to reach the object within 3 seconds, the homing attack is automatically cancelled.|
||Swimming||Similar to the flying ability, except this ability will work only underwater; attempting to use this ability outside of water will do nothing. Also unlike flight however, the ability can be used indefinitely while underwater. Characters with this ability will also be given the ability to run on water.|
||Double jump||Pressing jump a second time in mid-air will make the player do a second jump.|
||Floating||Pressing jump a second time in mid-air and holding the button down will allow the player to hold their vertical position mid-air continuously, similarly to Super Sonic's own floating ability but without the limitation of needing to move while doing so.|
||Floating with slow descent||Pressing jump a second time in mid-air and holding the button down will cause the player to fall at a fixed rate downwards, slowing down the rate the character falls down. This is similar to E-102 Gamma's booster powerup from Sonic Adventure.|
||Telekinesis||Pressing the jump button in mid-air will push enemies and players within a set radius around the player away; pressing spin in midair will pull them closer instead.|
||Fall switch||Reverses the player's vertical momentum when pressing jump in mid-air, thrusting them in the opposite direction instead.|
||Jump boost||The faster the player moves about, the higher the player's jump speed will be. Pressing the jump button in mid-air has no effect otherwise.|
||Air drill||Pressing jump a second time in mid-air will initiate an air drill, thrusting the player forward at the angle they're facing. The player will fly in an arc, eventually finishing the drill when the player is falling down to the ground. Holding the spin button while drilling will cause the player to descend more swiftly.|
||Jump-thok||A hybrid between the thok and the double jump. Gives the player a burst of speed and an extra jump with each use.|
Development mode itself has twelve different modes, each displaying different information, multiple of which can be displayed at once by combining the values of them together. Either the decimal or hexadecimal values can be used with the
devmode command – e.g.
devmode 4095 (or
devmode 0xfff) will turn all development modes on, and
devmode 0 will turn all of them off.
||Basic||Displays basic information on the HUD, such as the player's map coordinates and angle.|
||Detailed||Displays more detailed information on the HUD, such as the player's XYZ momentum, scale, and ceiling/floor heights, etc.|
||Randomizer||Displays information for PRNG seeds on the HUD.|
||Render||Prints rendering-related debugging messages into the console.|
||NiGHTS Basic||Displays basic information for NiGHTS mode on the HUD, such as timers for powerups, links and bumpers, amount left in the drill meter, and displaying milliseconds as well as seconds for the time left as NiGHTS. Also prints messages into the console signalling when the Ideya Drone displays the GOAL sign or not.|
||NiGHTS||When playing as NiGHTS Super Sonic, axis transfers are displayed in-game as a rail ring sparkle trail stretching outwards from the point of the axis transfer and at the height of the player. (Such trail actually hurts you though, so the |
||PolyObj||Prints PolyObject-related debugging messages into the console.|
||Gamelogic||Prints miscellaneous gamelogic debugging messages into the console.|
||Netplay||Prints multiplayer-related debugging messages into the console.|
||Memory||Prints memory-related debugging messages into the console, and displays the memory heap used.|
||Setup||Prints setup/initiation-related debugging messages into the console. This includes information for level-loading, loading files into the game, loading ghosts for Record Attack, MD5 computing, etc.|
||Lua||Prints Lua-related debugging messages into the console.|
|This needs some investigation.|

Specifically: Do these cutscenes actually exist in the game's data?
SRB2 was originally planned to have animated cutscenes between zones but it was unused.
