Not even a day has fully passed since you rescued the US president from Mexican soil and you and the rest of your Ghost team are on the way home. Then the General phones in and gives you your next mission: a group of terrorists deposited two dirty bombs (normal blasting compositions combined with radioactive material) near the city of Juarez. Your goal as Captain Mitchell is to once again save the day with your three team mates.
Like in the predecessor Tom Clancy's Ghost Recon: Advanced Warfighter you control Captain Mitchell and see everything through his eyes while you command your team mates either directly over the Cross-Com or with the help of the tactical map through the various environments to fulfill your objectives like blowing up a bunch of anti-air-vehicles and then raiding a rebel outpost.
Next to the slightly improved graphics and the additional environments such as the desert or mountains, there are several changes and improvements to the basic gameplay. You can now change the people on your team and choose between different entry points for the next mission. Besides the old checkpoint saving system you can also save whenever you want. Another addition is the possibility to pick up the weapon an enemy dropped, which allows you not only use the typical Ghost weaponry like the good old MR-C but also Mexican fabrics. Fixed weapons scattered throughout the levels like the mounted machine gun complete the new set of weapons.
Both the AI of your team mates and of your enemy has been improved significantly and you can give your squad four new orders and set two different rules of engagement in order to make the game even more tactical. Switching to the view of the team mate now shows exactly what he sees instead of the grid wire view from the original.
If you feel that the AI still isn't good enough, you can go online and play through the game with three other friends or play the three other classic modes: Deathmatch, Team Deathmatch, and Hamburger Hill in which a team needs to hold a central zone of the map a certain amount of time. There are also two new game modes available: "OGR co-operative" and "Recon versus Assault"
OGR stands for Original Ghost Recon. In this mode you play a specific mission in the old Tom Clancy's Ghost Recon-style. This means that you won't have any access to advanced technology like the Cross-Com system.
In "Recon vs. Assault" one side plays the Ghost team, which needs to destroy three Anti-air vehicles. The rebels need to avert that. In this mode a dead Ghost team member can only respawn once an ADAT is destroyed, but while in the spectator mode, he can still tag enemies for the units active on the ground. To defend against that, the rebels have access to a special class called the Scrambler which can detect and remove tags from friendly units. Every action you perform is awarded with veterancy points. As you gain more of those points you unlock more powerful gear which you can access at the MULE drones (Ghost team) or the ammo trucks (rebels).
