Approved Pro League Operator Skin Sets

Pro League sets are distinguished by a common set name shared across the four operators released that season. Approved sets include, but are not limited to:

  • Gold Dust — Y1 Pro League sets (Thermite, Ash, Mute, Bandit, Twitch, Fuze, Jäger, Thatcher, Sledge, Rook, IQ, Tachanka)

  • All subsequent Pro League set releases (Y4S2 onwards) up to the most recent season
  • Gold Pro League Champions skins — awarded via Pro League / Six Invitational Champions content

If a skin set is uncertain, the team must raise it with the Head Admin before the match. Any non-Pro-League skin found in-game will be treated as an incorrect skin.

  • No warnings or penalties for cosmetic usage in Division 3 matches
