Blizzard's official StarCraft II web site got a new update earlier this week with the posting of a new short story titled Collateral Damage. The short tells the tale of an assault by a advanced prototype of one of the Terran faction's more powerful units, the mech-like Thor. There's also a new gameplay trailer showing the unit in its multi-gun action.

In related news, AT&T has announced that it has expanded its previous agreement with Blizzard. AT&T's Internet Data Centers will be used to host Blizzard's online games for not just StarCraft II but also World of Warcraft and current and future games in the StarCraft and Diablo game franchises. The agreement was labeled a "multimillion dollar multi-year, multi-services contract" but specific financial terms were not disclosed.
