The man behind some of our favourite UT Jailbreak maps, our very own Spoondog, has made a revamped, remixed and regenerated version of his map Industrial Rage for Jailbreak 2003. I've just been playing it, and I can tell you it's as much fun as the original. He's added a new top level for extra action, and, naturally, cranked up the detail to the sort of level you'd expect for a UT2003 map.
Got a favourite UT Jailbreak map you'd like to see remade for the new version? Stop by our forum and let us know!
