Ubisoft announced today that the Deniable Ops Insurgency Pack downloadable content for Tom Clancy's Splinter Cell Conviction will be available from the 27th May on both PC and Xbox 360.

The DLC will cost 800 Microsoft Points on Xbox 360 while the PC price is "yet to be confirmed".

"The critically acclaimed Stealth-Action hit of the Spring takes aim at Xbox LIVE with additional content this month. The Insurgency Pack delivers brand-new missions for Archer and Kestrel on four additional maps for Deniable Ops modes. Take on challenges in Hunter, Face Off, Infiltration or Last Stand to unlock new achievements and play in settings from the docks of San Francisco to a New Orleans cemetery, a prison in Portland to a hidden research complex in Salt Lake City. Sam Fisher may have his conviction, but Black Arrow is still out there - waiting for him.

The achievements hunters will be glad to know that 250 new points can be unlocked in this DLC."
