The unstoppable Warhead was able to get the mod updated to the newest build of UT4. It wasn’t easy, there were issues, but he persevered. So he will now continue his efforts to bring the Chaos Hoverboard into the game (among other things). It’s a big project, but we are optimistic.
Also, Thatscrawnykid has posted this short video of what he believes will be the final art effects for the Hoverboard.
