Call of Duty: Ghosts

This year's installment of Activision's cash-cow, the Call of Duty franchise, Ghosts, by Infinity Ward, offers a memorable single-player campaign that sees you as part of an elite squad of American soldiers that resist the Federation (no, not Star Trek), an energy-hungry hegemony based in South America. You play not only human characters, but also a ferocious squad dog. The multiplayer component includes several interesting new modes. Based on Infinity Ward's latest in-house engine, Ghosts is simply stunning in some scenes; in others, it's a throwback to Modern Warfare. It should tax performance GPUs well enough with its DirectX 11 features.
