It's called Starxium 20XX and it's a retro-futuristic team-based competitive video game with cars, neon lights and 80s style synths.
It's a capture the point (your team needs to stay on a point and repel your opponent), where the point is a moving convoy that runs at 200km/h on the center of a big highway. It's not a racing game.

Most important is that I'd love to hear some feedbacks on the design and the concept ! It's actually not playable yet, but it's planned to be released as a public beta on Steam in late 2019.
Thank you very much :)
(Btw if ever you're interested in the concept, I just launched a kickstarter campaign ! https://www.kickstarter.com/projects/323689835/starxium-20xx )
