Though it is something you have to directly opt-into on Steam to access, anyone can access Update 47 for Lethal Company. Keep in mind that it is experimental, so there could still be bugs with it. However, thanks to players who have already accessed it, we do have a clear idea of update 47.
All of this information is thanks to YouTuber Wurps. Though keep in mind they are utilizing mods so their UI might look different than yours.
