The achievement “Infested Terror” (under Versus -> Unranked/Ranked) requires as follows:
Destroy 30 units with Infested Terrans in an Unranked or Ranked game.
Since there are no Infested Terrans in sc2 anymore (as of patch 4.11.0), this seems impossible.
Maybe the achievement should be moved to Feats of Strength then.
Considering “Infested Terror” can’t be achieved, “Supreme Being” (under Versus) can’t be achieved as well, because “Supreme Being” requires Infested Terror.
Note that going to Custom -> Melee and setting to HotS or WoL isn’t a solution as this wouldn’t be an Unranked or Ranked game.
Consider moving it from the Unranked/Ranked to the Melee Categorie.
