yeah no unit in the game has matched the hydralisk in terms of cost effective, and supporting role, and they are the undisputed backbone of the zerg army.
I watched a match once were this guy pwned just using hydralisk. I watched this noob game once were he lost because he neglected hydralisk. The hydralisk is the symbol of the zerg army.
Hydralisks are a sort of upgrade from the Marine. They have higher attack power and more hit points, but I think they may have lower speed (without the Hydralisk Upgrade), lower attack speed, and shorter range (after the Marine Upgrade), and higher cost than Marines.
If were gonna talk about the symbolic unit for zerg. What about maxxing out your supply with 400 zerglings! The single best reason to play world's fastest map.
Lets hope I dont kill this by getting back on topic, but wat about the animation for some of the spells. Marines gripping their head in pain as a Dark Archon Mind controls it. A zergling body glowing and exploding as a irridation hits it. How about plague on a group of terran infantry watching peices of there body rot and fall to pieces.
Always was kinda funny that everything explodes regardless of the cause of death. It's GoW all over again! Don't worry though: The nice puddles of blood will make you feel all warm and fuzzy inside once again. they can't get too graphic with the deaths because they want to keep a Teen rating.
