Welcome to SRB2.org!

SRB2 Logo

Sonic Robo Blast 2 is a 3D open-source Sonic the Hedgehog fangame built using a modified version of the Doom Legacy port of Doom. SRB2 is closely inspired by the original Sonic games from the Sega Genesis, and attempts to recreate the design in 3D. While SRB2 isn't fully completed, it already features tons of levels, enemies, speed, and quite a lot of the fun that the original Sonic games provided.

Version 2.1.3 Patch

Inuyasha - March 18, 2014

Sorry I don’t have the wit of Mystic, but I do have more bugfixes for everyone. This patch works with any previous version of 2.1 and fixes the following bugs:

  • Castle Eggman 3:
    • Fixed a crash when hanging on the center chain as it disappears.
    • You should no longer be able to dodge the spikeballs by standing up against the walls.
    • Minor map related modifications to make the pinch phase a bit easier.
  • Visual errors with objects extremely far above or below you have been fixed.
  • Fixed the game freezing in some circumstances without producing an error log; most notably in Red Volcano 1.
  • You can no longer pause the game in Record Attack or NiGHTS Mode.
  • Fixed the -room command line parameter; hosting on the Master Server through the command line is now possible again.
  • A few other minor map related fixes.
  • A few minor display issues were fixed.

Version 2.1.2 Patch

Mystic - March 17, 2014

As usual with a big release, we’re overloaded with bugs and we’re still in the process of hammering them out. This patch works for either 2.1.0 or 2.1.1 and fixes the following:

  • You can now collect the hidden emblems in record attack; you still can’t get the record attack emblems in the normal game, though.
  • Fixed a major issue with joining mid-round in netgames. Hopefully this should help deal with a lot of the quirky behavior netgames are currently experiencing.
  • Fixed an issue where adding WAD files while running a server would always remove you from your own server.
  • Fixed an issue with one of the secret stages being impossible to complete.
  • Fixed a bunch of little level errors.
  • Fixed a bunch of other minor bugs.

Please keep reporting any bugs you continue to find on the Bug Reports forum. You’ve all already been a big help in this regard.

Version 2.1.1 Patch

Mystic - March 15, 2014

Like every other release day, things never go off without a hitch. Head on over to the download page to download the patch. This patch fixes the following:

  • Fixed an issue that was causing people with non-English locales to have the following issues (among others):
    • Knuckles was unable to jump.
    • The camera was not properly following the player.
  • Nimbus Ruins should now properly work.
  • Touching a mine in Deep Sea Zone should no longer crash the game.

If you find any more bugs this patch doesn’t fix, please head to the Bug Reports forum to see if it’s already been reported, and if it hasn’t, report it. Hopefully we can all nail down these issues and get 2.1.X stable in the near future.

Version 2.0.7 Release

Mystic - September 10, 2013

Well, finally, here we are at…wait, 2.0.7? Yep, nothing truly exciting, but a significant bug was found and needed to be corrected immediately, so we’re releasing a simple hotfix patch. This release contains no new content, but includes the following bug fixes:

  • Fixes a major issue with netplay that caused the game to be hypersensitive to denial of service attacks.
  • Fixes an issue with lasers in netplay causing consistency failures.
  • Fixes a rare crash when using F12 in Capture the Flag mode.
  • Low framerate should no longer cause screenshots to be taken improperly.

Head on over to the download page to get a copy of the patch.
