Activision and Treyarch have just released a brand new teaser trailer for the upcoming, second Call of Duty: Black Ops DLC map pack, Escalation.
Escalation is a timed exclusive, releasing first for Xbox 360 on May 3rd (or May 4th here in New Zealand). If the precedent set by the first DLC package, First Strike, is anything to go by, the PlayStation 3 version should follow roughly a month later, with the PC version coming another month afterwards.
Also recently announced is that Call of Duty: Black Ops is headed for Xbox LIVE Games on Demand. A price or release date has not yet been set (let alone whether it will be available on the New Zealand marketplace), but Microsoft did announce a date: May 3rd, the same as that for the launch of Escalation. Again, if it does indeed reach the New Zealand marketplace, it's likely to be available here on May 4th.
Without further ado, here's the latest footage of the Escalation map pack in action:
