The second DLC pack for Crackdown 2, Deluge, will be available November 16th. It will include ten new achievements for an additional 250 gamerscore, bringing the game's total to 1500. The Horde/Firefight style DLC will run 560 Microsoft Points.

However, one achievement will require more than just the Deluge DLC if you want to max your gamerscore on Crackdown 2, as the "Project Sunburst" achievement requires that you have played and transfered an upgrade from the upcoming Windows Phone 7 game, or at least know someone who has. No release date or price has been set for the WP7 game, but expect it around the 16th to coincide with the Deluge.
