Ubisoft has unveiled the ‘Insurgency Pack’ DLC for Tom Clancy’s Splinter Cell: Conviction, set to arrive for Xbox 360 and PC Thursday, May 27.

The content will run $10 (800 MS Points) on the Xbox 360 and brings four new maps playable across all four of the Deniable Ops game modes. The maps include a New Orleans cemetery, the dock in San Fransisco, a prison in Portland and a under-wraps research lab in Salt Lake City. 250 new achievement points will also be included, though the publisher didn’t divulge any more info on how many achievements that adds up to or what they entail.

Pricing for the PC has yet to be announced and no word if this will interfere with Ubisoft’s previously promised free weekly content plan.
