Complex: "Ghost Recon: Future Soldier has clearly been created by developers who understand the innovations that have occurred since the last Ghost Recon game came out. The really essential question, then, is do those innovations add to Future Soldier, or has Ghost Recon lost too much of what it was before?" 8/10
Exactly, Halo only refined the FPS genre. Call of Duty 4 was the leap in the genre, it introduced killstreaks and even if it wasnt the first game to have unlocks it perfected the "carrot on a stick" reward system. Halo is just an evolved Unreal Tournament. Both are good games too.
Or is Cod4?
