On November 16, the "Deluge" downloadable content pack for Crackdown 2 launches for 560MS Points ($7). Included in the pack are "updates" to the weapons and vehicles in Crackdown 2, a capture the flag variant called "Capture the Orb," and a new mode dubbed "Deluge." In Deluge, up to four players must battle against waves of enemies throughout Pacific City.
If you'd rather test the content before commuting to a purchase, the "Deluge Pack" will be available in a trial version--giving you a chance to play the new modes for free. Purchasing the content nets players new achievements and Avatar awards. You can watch all the fresh action in a trailer after the break.
For Windows Phone 7 enthusiasts, playing the mobile title Crackdown 2: Project Sunburst will unlock special bonuses hidden within the Deluge DLC. On the streets, they call that synergy.
While I suppose "commuting to a purchase" can make sense if you're going for an overly complicated metaphor or pun, I don't think that's what you were intending.
