Queen, Corrupter, Ultralisk, and Mutas all look great. Most units look very good really. The only unit I’ll complain about other than the Infester is the roach. I’m fine with making it easy to distinguish from other units, but right now it looks awkward instead of scary, creepy, or Zergish.

+ points: Corruptor has sinister sexy movement animation,
-the queen distinguishes zerg gameplay-wise and is burgled barefaced from aliens, class.
- Nydus worm is a cool concept for zerg transportation and looks rawsome. -Ultralisk attack is badass powerful yo.

- points: Corruptor and Infestor are laughable names. They sound like slayer songs. Is blizzard alluding to obscure metal bands from the eighties that no-one can remember or are they just strapped for monikers? (Or both?) Seriously man: INFESTOR! (cue guitar/bass pounding)
-I could imagine Ash Ketchum commanding the new lurker in battle but not Kerrigan
- Infestor design is Kentaro Miura level URGH. It looks like a pitlord who was pretending to be a demon hunter when he got his head cut off, and subsequently sprouted extraneous legs/mouths. His infest ability strongly evokes explosive/ projectile dysentry. It would be embaressing to field these corpulent zits. I heartily approve of the zerg being repulsive but this is simply tacky.
Finally – buildings. The zerg base now resembles a clearasil commercial. I cannot view the hatchery/lair as anything but immense, rosy turds. The others are plastic enough to be mcdonalds toys. It is not the actual architecture so much as the fact they are not interacting with the surface at all, zerg buildings should be alive, have an entire gastrointestinal mess beneath them; bifurcated arteries palpitating the entangled creep, fields of waving epethelia fanning out from the radioactive green, cascading endocrine pools.
It makes sense for the toss/terran to have neat distinction betweem terrain and structure (warping in, aerial migration) but the zerg should look like an embedded organ system, vile and interconnected. Vivify these happy meals blizzard.

-Note: I know the zerg are still morphing, and this is not meant to mock the dev team who I’m sure are sweating to make this game all it can be, I simply wanted to convey the full distaste that my reaction included so as to provide honest feedback. Mad props sc2 team, you are the rad.

The roaches seem a little odd to me – just a ground based unit that regenerates quickly.. Maybe if they could move while burrowed as well, that would make them more exciting to me! But as others have said, we haven’t really seen them in action, so it’s too early to pick it apart.

Regarding the missing commentary, maybe there’s still one to come? Although I personally didn’t like the fella’s voice – he sounds too marketing-speak for a my tastes! Although they should do another one (20 minutes! with all units!) just to be consistent.

And from an aesthetic point of view, tanks that aim at their targets and ships that bank in the air would be great. whether this would put too much strain on a game designed to run on a wide range of systems is another matter.

“The lurker is a returning unit from starcraft, and it still burrows and attacks with rows of sharp spines that deal splash damage to all units in a line. The neemy is now sending his stalkers in to attack, and has foolishly not brought along any detection, allowing our lurkers to tear them up with ease and force them to blink away.”

“Roaches are more like vultures than like Ultralisks.”

I totally agree. It would have been better though if they show the roach in the gameplay a little bit more. We know very little about it. Even the new Ovies are not shown.
