Quick Scoop: I couldn’t verify a Reddit-specific step for party fill in PUBG: Black Budget from the available sources, but the most relevant community info points to the game being in playtest/alpha and discusses joining it through Steam’s playtest request flow.

What to try

  • Open the squad/party settings before starting a match and look for a toggle labeled Party Fill , Auto Fill , or Fill Team.
  • If you do not see it in the main lobby, check the mode selection screen right before matchmaking.
  • Some PUBG-style games hide this option until you pick a team-based queue, so solo queues usually won’t show it.
  • If you are following Reddit advice, make sure you are looking at posts from the PUBG: Black Budget community rather than older PUBG posts, because naming and menus can differ across titles.

Reddit context

Reddit discussion around PUBG: Black Budget is currently focused more on playtest access, alpha impressions, and account linking than on detailed menu walkthroughs. That means the exact party-fill toggle may simply not be widely documented yet. The Steam community page confirms the game is an extraction shooter under the PUBG: Black Budget name.

Best next check

  • Look for the queue type first.
  • Then inspect any team or party submenu.
  • If the option is missing, it may be unavailable in the current build or restricted to certain modes.

“Request Playtest” is the most clearly documented entry point for the current PUBG: Black Budget build.

TL;DR: I couldn’t confirm an exact Reddit answer for turning on party fill, but the likely place is the mode/team settings before matchmaking, and current discussion suggests the game is still in a limited playtest state.
