Hoverless would be same as normal any% but you do the proxy into ruins, extended frontflip in ruins, and do IFG(infinite flight glitch) in dark ship, it would barely be a 10-20s difference
It would be a really pointless category for Jak 3. It only changes a bit of ruins and dark ship, as Blaust said.
For No OoB Hoverless the run really wouldn't change much at all except for economy mines. And for that we would just do proxy (given it's clearly in bounds) or jetboard down after cutscene and take elevator up. So the run just becomes more autisty.
After the recent Twitch changes to VOD storage that you've surely heard about, we've decided to no longer accept Twitch VODs for submissions to the Jak boards. From now on, only YouTube links will be accepted for video proof in a run submission, and we would encourage you to export any previous runs
