The Shredder was one of the new units for Heart of the Swarm, revealed during BlizzCon 2011. In April 2012, Blizzard announced that the Shredder wouldn't be kept in the final version of the game, since it was perceived as very confusing for the players. It was indeed used to kill a large number of workers with little to no warning, and rarely for its intended role of map control. It was replaced by the Widow Mine.
- Official Blizzard description: "The Shredder is a new unit built from the Factory that allows the Terran player to control the battlefield. In its mobile form, the Shredder has no attack -- but when set to stationary mode, it channels area-effect damage to both the air and ground. If a friendly unit enters the range of the Shredder, the weapon shuts off."
