If you're looking for something that emulates The Expanse specifically and with PbtA system, there is no game that will do so without modifications of one sort or another. You would have better luck with more traditional games, like perhaps Deep Space for Cyberpunk 2020, or Transhuman Space and the Deep Beyond expansion, or something along those lines. But even then, they would probably require some tweaks.
Thanks, but what is SWN and WoDulBreakers?
