Veterans of previous Conflict games would have no problem with missions and game play. Your favorite heroes Bradley, Jones, Conners, and Foley from the previous games are back. As usual each one of the characters has a specific specialty, so you should use their specialty to your advantage. For example, Jones is a demolitions expert so equip all C4 with Jones, and Foley is an expert sniper so use him when you need a surgical stealthy hit. Your squad can carry and use an array of weapons such as the M60E3, M4A1, and the MP5SD silenced machine gun.
For any gamer that is a rookie to the Conflict series there is an excellent, and I do mean excellent, training mode that guides you through almost every situation that you will come across in combat. This feature is absent from most military shooters. One thing that I do miss from this Conflict game is the angry Drill Sergeant yelling at you throughout the training sessions. I felt the Drill Sergeant was a cool addition and it gives the game some realism. Something Pivotal Games should have left out is the music. The menu music at the beginning of the game is quite terrible. It sounds like something out of an 8-bit Nintendo game, but who purchases a military shooter for the music?
One of the amazing new additions to the physics engine is the ragdoll effect. When you kill an enemy, they die in an ultra-realistic fashion. In most military shooters after you kill the enemy, they simply fall to the ground. In Conflict: Global Terror, the enemy will actually fall and their body will fold depending on their environment, thus giving it a ragdoll effect. I must give all the credit to Pivotal Games on this one, its really cool and you'll find yourself watching enemies die and fold in a realistic manner. Similarly, your squad can Vault through windows, climb onto ledges, and use zip lines interacting more with the environment. A better graphics engine also gives Conflict: Global Terror smoother graphics, with improved animations and cut scenes.
I particularly like this approach which Pivotal games takes with the Conflict series. In Conflict: Global Terror (as in the previous Conflict series) your squad members actually run low on ammo. Some gamers might blame a poor AI implementation, but it's a dose of realism. It's not appealing to know that your team never runs out of ammo. However, in Conflict: Global Terror your squad members actually tell you they're low on ammo. This feature adds to realism and reality. It forces you and your squad members to conserve ammo and think quickly on your feet to grab enemy weapons nearby. Unlike, a majority of squad based shooting games such as, in Conflict: Global Terror you are allowed to switch between members of your squad. Likewise, you can use medical kits to heal yourself and your squad members as well.
