The closest thing to a Starcraft 2 zerg update that we have at the moment are the 2 screenshots released by starcraft-source (the third one, being a TvT screenshot).

You might be wondering what the green explosions are. At first glance one might think that blizz might have decided to change the Zerg’s blood color to green but Karune explained that those are actually from the baneling’s self-destruct/dying animation.

Mutalisks look and feel like gargoyles from Warcraft 3 but they aren’t really new stuff since we’ve seen them in action before on previous Starcraft 2 sneak peeks (Screenshots and Videos). The biggest star for this batch of screenshots would be the Overlord, making it’s first appearance on the second screenshot. As you can see, the overlord’s model is very similar to Starcraft 1’s, and it’s a welcome sight for those who are just dying to see some zerg updates. The biggest mystery now would be the the pack of zerglings on flame on the first screenshot. Clearly, no firebat could have ever charged into the fray over there since the ramp is blocked by zerglings, thors and a couple of terran buildings. It could be from the thor but if that was the case then the zerglings would have been blown to bits instead of being set aflame.

Quests:
• Fixed various known issues which prevented players from being able to continue interrupted side-quests.
• Quest items should no longer remain in the player inventory after the associated quest has been completed. Players with old quest items (such as Train Parts) associated with quests they’ve already completed or no longer have should find these items removed upon logging in.
