GameSpot writes: "Splinter Cell: Conviction's first substantial downloadable add-on may be "just" a map pack, but boy is it a good one. In fact, if you enjoy Conviction's excellent cooperative modes, the Deniable Ops Insurgency Pack is a must-play. These four standalone missions are even better than those included with the main game, filled with numerous nooks and crannies in which to hide, winding pathways and corridors useful for flanking, and dramatic opportunities to bring down your vocal foes. Those occasionally dimwitted enemies can get confused in these intricate environments, but bewildered combatants and other minor complaints only slightly soften the impact of this excellent addition to Conviction's outstanding co-op play. This pack may sell for 800 Microsoft points ($10), but it is too good for Splinter Cell fans to miss."
