Jazz Jackrabbit 2 Plus (JJ2+) adds countless features and bug fixes to both Single Player and Multiplayer gameplay within JJ2, and is used almost universally by most serious players. It has much better network code than the original game, adding console commands to online games, fixing most major game-crashing errors and connection problems, allowing permitted clients to log in as "remote administrators" in someone else's server and control the gameplay, and adding several new multiplayer gamemodes. It additionally fixes or enhances many of the events in the game, and allows level designers far more power than in regular JJ2 through the addition of an easy-to-use scripting language. JJ2+ takes everything great about JJ2 and adds so much more on top of it; it is truly a must-download. JJ2+ is distributed under the MIT license.

Although version 5.10's long development period meant that it underwent more prerelease testing than possibly any other JJ2+ update, it touched so many important components of the game that a number of oversights still slipped through to release. Most of those (we hope) are fixed here in 5.11. Running multiple game instances simultaneously, saving after playing multiple other levels, and clients not downloading the right files from online multiplayer servers are the highlights here. Other fixes include player physics interactions between Spaz's melee attack and certain slopes, horizontal vines and high speeds, and bullets and frozen enemies, as well as some new possibilities for loading external sound files.

But because this is a fairly short changelog, it's also a good time to talk about our issues tracker. It's always the first place you should go to report bugs or to suggest new features. Ideas like the 800x450 widescreen resolution have originated from there. But we also have a lot of opportunities right now for people to test or volunteer for things:

  • We have a number of proposed changes to player physics. These are intended to make gameplay feel more logical, but have an inherent risk of confusing or alienating people used to the older, buggier code. Feedback from players both experienced and casual is important here... a couple fixes were already incorporated into 5.11, but others (like the one pictured below) are still up for discussion.

    One proposed physics fix.

  • Another public test build provides some different models for deciding whether bullets hit players in online servers, to see if any of those other models feel better when lag gets involved.
  • We're also soliciting feedback about the player physics details affected by the /quirks chat command, and whether they should be incorporated into a new multiplayer gamemode devoted to the parkour-like "test" maps that have been popular since JJ2's early days. If you use any of the /quirks settings outside of test maps, we'd love to hear from you.
  • JJ2+ has added a lot of new messages, settings, etc. over the years, and this doesn't give the best experience for people who want to play the game in a language other than English. We'd love to find volunteers who can translate JJ2+'s new strings, especially into languages that unpatched JJ2 is already translated into, like German and Italian and Afrikaans.
  • One very specific opinion/game design question: in Capture the Flag matches, would you like to know how much health your team's flag carrier has? If so, how should that be represented in the game's GUI?
  • Of course, we have an open call for volunteers to playtest private builds with upcoming features and fixes.
  • More testing opportunities coming very soon!

Is this compatible with jazz jackrabbit 2 the secret files? I would like to play with Lori in that version.

I think it's a good time to bump it up, both JJ and JJ2 were released on GOG today.

Game of my childhood... Sure brings back memories.
Anyone knows if there's a site where I can download the extended versions of the music from the game? Not a simple loop, but one the starts at the right moment to properly connect to the end of the track.

Try deleting your .cfg files so that they can be restored to their defaults.
