Sonic Robo Blast 2 is a free 3D Sonic the Hedgehog fan-game built on a heavily modified fork of the Doom Legacy source port of Doom. It is closely inspired by the original Sonic games from the Sega Genesis, and attempts to recreate their classic design in 3D with robust multiplayer and mod support.

  • Old-school Genesis-era platforming complete with rings, springs, baddies, reversible gravity and more!
  • Fast-paced multiplayer action with support for up to 32 players online or 2 player splitscreen across multiple game modes.
  • 3 playable characters - Sonic (Speed), Tails (Flight), and Knuckles (Power) - traversing unique stage paths and carefully balanced for online match play.
  • Deep exploration spanning a variety of locations, from green meadows to deep underwater ruins, mines, mountains, and space stations - or perhaps more...
  • Original soundtrack produced by some of the most renowned Sonic music artists on the internet.
  • Loads of unlocks to keep you busy far past completing the single-player campaign, including hidden levels, game modes, and cheats!
  • Extensive configuration support for modern Keyboard + Mouse controls, or more relaxed gamepad controls, with individual sensitivity sliders.
  • Tons of user-created content - custom characters, levels, mods, and all sorts of other good stuff to extend gameplay well beyond the initial package.
  • Well-supported level design tools (such as Zone Builder) that allow easy creation of your own custom stages. (See SRB2 Wiki: Level Design for more info.)
  • Flexible mod support via Lua scripting or Sonic Object Configuation system - allowing new items, enemies, bosses, scenery effects and (much) more.
  • Full source code for the game available on GitLab and GitHub.

Sonic Robo Blast 2 v2.2 has been released! Grab it now from ModDB Downloads or srb2.org!


From Rob at srb2.org:

Hey all. 5 years. It's been a wild ride for us, but we're finally done. [...] I'm not going to bore you with an incredibly long post, so I'll keep it super brief. I want to give a heartfelt thank you to all of you who stuck with us over the past 5 years, and to all of you who helped contribute along the way. This release is a major milestone for all of us. We've been hyping up that 2.2 is a massive upgrade in virtually all respects, and I hope that you won't be disappointed. On behalf of the development team, enjoy!

Version 2.2

Sonic Robo Blast 2 v2.2 Full


General

  • Slopes have been implemented into almost the entire campaign, including support for launching off of quarterpipes. No, before you ask, loops still aren't possible.
  • An enormous number of graphics and textures have been updated or redone. Highlights include the title screen, Sonic and Tails, with separate sprites of Tails's tails for optimum mofumofu.
  • Practically the entire soundtrack has been redone.
  • Character sprites now face the direction the player's control inputs point instead of in the direction the camera is facing.
  • Automatic braking, a new assist feature, has been added. While enabled, releasing the controls will cause the player's character to attempt to stop instead of coasting forward.
  • Tails's AI has been significantly improved in Sonic & Tails mode, including allowing him to be commanded to fly you without using player 2's controls.
  • The attraction, elemental, and force shields now have a jump-spin ability like whirlwind and armageddon already did.
  • Continuing the game after getting a game over now starts the player with more lives for each continue used.
  • The intro cutscene has been revamped with brand-new art, and the game now has a short ending sequence.

Levels

  • Arid Canyon Zone Acts 2 and 3 now exist.
  • Almost the entire rest of the campaign has been remade from scratch or significantly updated.
  • Several bosses have had their arena and behavior updated.
  • The final battles have been adjusted to make losing not kick the player all the way back to the beginning of Eggrock.
  • A short, optional tutorial stage has been added.
  • Two stages previously from the OLDC have been included as unlockables.
  • Cooperative mode now uses the old 2.0 special stages, which have been slightly updated to be more multiplayer-friendly.

Interface

  • The menus have been massively revamped to both look better and be easier to understand.
  • Controls, menus, and various other things have been renamed to make them easier to understand.
  • Record attack now has HUD elements to display the buttons being pressed both during gameplay and while watching replays.
  • Multiple accessibility features have been added, including closed-captioning and the ability to adjust the palette at runtime to add contrast to aid colorblind players.

Engine/Editing

  • The palette has changed again to provide slightly more diverse color options
  • Music no longer restarts from the beginning after an interruption, such as getting an extra life.
  • Plugging in a controller during gameplay will allow that controller to be used instead of requiring the game to be restarted to recognize it.
  • Added support for paper sprites, which allow the sprite to be rendered as if it's on an upright piece of paper, becoming thinner when viewed at an angle and disappearing entirely when viewed from the side. Think Paper Mario.
  • Textures can now be used as flats (but not vice-versa).
  • Skybox rendering has been significantly optimized.
  • PNG images can now be used as graphics, at any resolution (but not too high or you'll run out of memory).
  • Sprite rotation is now supported.
  • libopenmpt support
  • Added support for the MD3 model format.
  • So many Lua changes we couldn't possibly hope to list them all here.

Finally, as a reminder, the wiki is going to be out of date for a while until people have time to update it, so be aware that editing documentation is going to be sketchy until those updates are made. We recommend playing vanilla while you wait!

first of all i just want to say this game is amazing, thank you so much
for crafting such an amazing piece of software. however i do have a couple recommendations, first on the list is please tweak some of the gravity and physics sonic is a little slidy for me. secondly is could you adjust the size of the items like springs and ring boxes they're hard to pin point. and lastly could you add a homing attack feature i often find myself drifting around enemies. but aside from these this is probably the best fan made indie game ive ever played id rate it 9/10

Hey everyone, sorry for the lack of updates and comments. I've gone through and cleaned up the profile - OS listings should be accurate (see Mb.srb2.org), among other things.

Will at some point get recent material posted over here (see Srb2.org in the meantime for some 2.1 tidbits). Remember, SRB2 is free and all parties involved donate their free time towards further development, so patience is appreciated. ;)

Thanks!
