"Some experimental physics that I slapped together in Xonotic. It's essentially Quakeworld with more air control and acceleration. Step height is similar to default Xonotic, which allows you to glide stairs without losing speed. You can also wallstrafe and get a huge boost, however the angles are bit different and you can't do it with your feet off the ground as easily.

Keep in mind that you don't gain speed by simply moving forward, you need to turn and steer in ground/air and there's an optimal curve that gets you the most speed. The physics are easy to learn and it's about as fast paced as you are.

Try it yourself: https://www.dropbox.com/s/t4nspo2ggnfgrjr/physicsCIX.cfg?dl=0

Put it to your config folder or xonotic-data.pk3 and and write "exec physicsCIX.cfg" to console. You're obviously gonna need Xonotic as well. " - Smilecythe
