In an unexpected playlist update for Call of Duty: Infinite Warfare on PS4, Infinity Ward accidentally pushed out a DEV Category of playlist testing for the game to the public.
This DEV Playlist is supposed to be for Infinity Ward / Activision employees to test out the game and features before they go public for launch and not meant for public players.
The Playlists reveals that Infinity Ward is apparently testing out SBMM, which is Skill Based Matchmaking. SBMM was a big issue during Advanced Warfare days, where players thought Skill was being factored into the matchmaking over a good connection. SHGames stated that they had toned it down, but still left players angry.
Again, we cation that these are all testing playlists and none are expected to be made public at this time.
