Australian retailer Game has supposedly leaked an e-flier for a new Black Ops DLC map pack entitled Escalation.

The pack comes to Xbox Live first on May 3 (the month/day date format on the flier is reversed for much of the rest of the world), and later on an unspecified date to PS3 and PC (like First Strike).

According to the flier, the pack will include a zoo, hotel, convoy, a stockpile, and the zombie level call of the dead.

We're excited to see what these maps have to offer, and hopefully Activision says something official about Escalation soon.
