A new No Man's Sky update has been released to the game's experimental branch that brings some improvements to the Holo-Arena.
No Man's Sky recently received a big new update titled Xeno Arena, which introduces a Palworld-esque creature battling system (I'm sure there's another game with creature battling, but none are coming to mind), and while that may sound weird for a space exploration sim, it's actually a feature that fans had been requesting for years.
