Seems super hectic and "unbalanced" (I don't know how balanced a battle royale really gets, they're all just wars of attrition and the culling process can be arbitrarily mean no matter if it's fun or not.) But I do love the repurposing of classic gameplay and game model to do something brand new, and the 99 BR style can be really fun. Will check it out.
The Skyway thing seems like it actually makes this work, otherwise it would just be pure chaos and you would either drag ass in the back to avoid contact or you would bolt out front and race like your life depended upon the pack not getting close to you. The path seems to be an extraordinarily assistive boost (you can go from last to first so easily) so I'm not sure how much of a cheat that'll end up being (seems like perfect timing of skyway would be the ultimate cheat strategy,) but as I see it working, it's necessary for this game to have any kind of fairness and strategy. Otherwise, it's just bump-and-hope gameplay unless you're in the very front or very rear.
