Blizzard Entertainment posted a new StarCraft II: Heart of the Swarm teaser image in Facebook.
The shadowy silhouette hints at some sort of arachnid. What comes to mind is a support unit with an AOE web to neutralize large packs of zerglings, marines or zealots. Similar to Ensnare. The spikes in its belly and legs might suggest it burrows. Could this unit somehow be the Lurker replacement with extra utility abilities?
The heavy armor and the cannon-like spider-rear also looks like … a zerg siege-tank? Overkill.
What’s your personal speculation?
