Tom Clancy’s Ghost Recon Advanced Warfighter 2 (GRAW 2) is a tactical shooter video game developed by Ubisoft Paris and Red Storm Entertainment and published by Ubisoft. Much of the gameplay remains the same as it did for GRAW – emphasis in GRAW 2 is on the player doing the bulk of the fighting as Scott Mitchell, while relying on tactical combat instead of arcade run-and-gunning to overcome opponents. Like before, weapons featured in the game are either based on actual models (such as the FN SCAR) or are hypothetical prototypes, with the player able to command friendly units assigned to help them, from their own squad, to drones, tanks and aircraft. Like its predecessor, GRAW 2 features two different versions; while both the Xbox 360 and Playstation 3 versions are essentially the same title, and the Microsoft Windows version features many differences to these, both maintain the same story. In addition, both games feature a new and improved gameplay element – Crosscom 2.0 – a few new weapons (including sub-machine guns for secondary weapons), the ability to have a medic in the squad when commanding a squad, and new friendly units to control, including a two-man squad of Loyalist troops, the MULE Drone, a Little Bird attack helicopter, and Far Support (Airstrikes for Xbox 360/Playstation 3, Mortar/Artillery Support for Microsoft Windows).
