Gears of War 2 builds upon the gameplay of the first title in every way. First, the scope of the action is bigger: new characters, more weapons, nastier enemies, bigger vehicles, and grander locales offer more action, more emotion, and more thrills. Next, every major aspect of the game has been refined to create heightened, more immersive experiences. Finally, the overall tone of Gears of War 2 is more badass: replete with new weapon-specific executions, chainsaw duels, and shocking boss fights. Gears of War 2 raises the graphics bar for next-generation games through its breathtaking visual effects, which are made possible through advances in Unreal Engine 3. New visual effects include ambient occlusion, dynamic shadows, improved character lighting, the ability to render hundreds of on-screen characters simultaneously, improved water physics, additional blood and bullet decals, advanced destructible environments, new weather effects, and the introduction of fluid objects. When combined with the sweeping vistas and evocative locales in the world of Sera where the Gears of War 2 story unfolds, these additions help make this the most gorgeous game available this generation. Gears of War 2 continues to push deep, immersive storytelling in video games to greater heights. Humanity's epic battle for survival is felt on both the personal and epic levels as you explore multiple story arcs that introduce new characters and flesh out the histories of familiar ones. A new in-game conversational camera system also helps bring the compelling story to life in a cinematic fashion. [Microsoft]

Amidst a backdrop of worldwide ecological and seismological chaos in the mid-2100s, the United States has been split in two by the "Great Flood". As a result of the polar ice cap melting, the Mississippi River has destroyed the central portion of the United States, causing an ill-equipped Federal Government to fail and literally cutting the country in half. These two halves are left to fend for themselves in the aftermath. The East, now known as the Atlantic Alliance, symbolic of their union with Europe, puts its faith in surviving this new world in cybernetics, an established yet evolving technology now more than 150 years old. On the other side of the flooded continent, the Western states, now called the Republic of Pacifica and having allied with Asia, resort to solving their problems at the genetic level, effectively restructuring the DNA of its inhabitants -- a method the Atlantic Alliance finds morally reprehensible. By 2161, it only takes a hint of unauthorized military preparation in Pacifica for the newly restored president to order a strike in the heart of Pacifican territory -- an outpost in the now dry San Francisco Bay. This strike leads to the unthinkable: an epic conflict with global implications fought on U.S. soil. As a soldier in this struggle, Mason Briggs uses explosive, terrain-deforming weaponry to change the face of battle: He not only destroys the land in his path, he outright transforms it to gain the strategic advantage in completely unscripted ways no game has ever seen. With such a devastating arsenal at hand, Briggs never leaves any battlefield the way he found it. In addition to weaponry that allows players to do things previously only imagined, each side of the conflict, Pacifica and the Atlantic Alliance, boast soldiers with powers beyond those of ordinary men. Genetic augmentations provide Pacifican forces with amazing abilities, while Atlantic Alliance soldiers like Briggs counter the threat with the more "traditional" method: cybernetics. The differing states of superhumanity result in balanced yet stylistically different combat tactics that have never been seen before. [LucasArts]

Star Wars: The Force Unleashed casts players as Darth Vader's "Secret Apprentice" and promises to unveil new revelations about the Star Wars galaxy. The expansive story, created under direction from George Lucas, is set during the largely unexplored era between "Star Wars: Episode III Revenge of the Sith" and "Star Wars: Episode IV A New Hope." In it, players assist the iconic villain in his quest to rid the universe of Jedi - and face decisions that could change the course of their destiny. Unleash and upgrade the Secret Apprentice's four core Force powers - Force push, grip, repulse and lightning - throughout the course of the game, and combine them for ultra-destructive, never-before-seen combos. The Secret Apprentice doesn't just Force push enemies into walls - he Force pushes enemies through walls. The Secret Apprentice doesn't just Force grip foes to throw them aside - he Force grips them in midair, zapping them with lightning, then dropping them to the ground to explode like a bomb. In addition to new adversaries created just for the game, such as fugitive Jedi and Force-sensitive Felucians, players also confront and associate with familiar faces from the Star Wars films, including Darth Vader. Visit locations such as Episode III's Wookiee homeworld Kashyyyk and the floral Felucia, the junk planet Raxus Prime, plus an Imperial TIE fighter construction facility. Decisions made by players throughout the game determine the path of the story, including multiple endings that will rock Star Wars continuity as they know it. [LucasArts]
