The Zerg Queen can be described as a WarCraft III Hero, of a sort, as it is just one of a kind, and every Zerg player must have one. Or is it really? StarCraft: IncGamers has the inside scoop on The Queen of your Hive Cluster.
"There has been a fear for adding 'hero' units in StarCraft II from the community, and seeing this new Queen unit chopping away Marines with abandon is slightly unnerving for anyone of us. The fact that she 'upgrades' and gets better with time will ring another alarm bell, but this isn't really the truth. Yes, a fully upgraded Queen is rather powerful, but if you kill her, your opponents needs to spawn a new one and evolve her in two steps to have her back."
