About the Operation Breakout Weapon Case
Released on July 1, 2014 with the "Operation Breakout" update, Operation Breakout Weapon Case is one of the easiest iconic cases in the game to describe. This is the case that players associate with the Butterfly Knife debut.
That single fact has carried the case for years. The rest of the pool matters, but the butterfly origin story is the reason the market still cares and why players still compare every later butterfly case back to Breakout first.
