Not sure how much BR mechanics it will have, but Fall Guys: Ultimate Knockout looks intriguing.
I wasn't that into BR games but I'm very burnt out on them. They need some heavy innovation. I've wanted a mech-based BR game for a while now but I don't even think one is in production. Where you start out in mechs and have to collect parts instead of weapons. It would, in practice, be almost like a mech based deathmatch, but with the addition of starting with nothing and scavenging. It seems like it could be fun, at least in my head.
