This stand-alone add-on for Xbox offers new missions, maps, and modes that continue the gameplay set forth in the original Tom Clancy's Ghost Recon 2. Developed by the series' creators at Red Storm Entertainment, Summit Strike includes 11 single-player missions and 15 new weapons. Multiplayer gamers are challenged with a total of two dozen squad-based, solo, and cooperative game modes. The new "Heli Hunt" mode has players avoiding detection by -- and whenever possible, eliminating -- resurgent fleets of enemy 'copters that seek them out. "Armor Strike" mode has opposing teams infiltrating each other's territory and competing to "laze" the most enemy armored vehicles for destruction.
