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.
This is the most recent version of JJ2+! This release largely serves as an update to the previous download, which means that it brings all the awesome new features and fixes from a couple weeks ago--mouse aiming mode, new textured backgrounds and tile types, new Turbo difficulty for single player, enhanced control over the HUD and object behavior for scripters, and more--but also with increased stability. We've addressed some edge-case crashing issues, worked out some kinks with the object synchronization netcode, and made a bunch of other fixes as well. Also it's now easier to configure your controls or to kick people who join your server for spamming. As ever, the full changelog can be found in the included readme document.
