In Call of Duty: Modern Warfare 2, developer Infinity Ward aims to ratchet up the intense first-person gunplay, graphical verisimilitude, and deep multiplayer experience that won the original title wide acclaim from critics and consumers alike, while at the same time adding to the overall package with the new, fast-paced "SpecOps" mode. The single-player campaign picks up where Call of Duty 4 ended, with gamers once again descending into the shadowy world of terrorists, arms dealers, and nationless armies. Players take on the role of Sergeant Gary "Roach" Anderson, an elite member of the multinational Task Force 141 and subordinate of one of Call of Duty 4's protagonists, John "Soup" MacTavish.

Task Force 141 is on the trail of Vladimir Makarov, a maniacal disciple of Imran Zakhaev, who has used the death of his mentor as a means of expanding his own base of power. Missions find gamers working off sketchy intelligence as they battle whiteout conditions in the jagged mountains of Russia and Kazakstan, shuffle though expansive desert and cave environments in Afghanistan, and weave between City of God-like Brazilian slums, where misfires result in dead civilians and a failed mission. As was the case in Call of Duty 4, Modern Warfare 2 supplies players with the most technologically advanced weapons, vehicles, and accoutrements available, including SCAR-H rifles, snowmobiles, and heartbeat sensors.

The new "SpecialOps" mode brings gamers more than 20 fast-paced missions inspired by the frenzied mid-fuselage gunfight at the end of Call of Duty 4. Players find themselves racing snowmobiles, battling a huge number of enemies at once, or simply attempting to get in and out of a building without dying, and missions can be played solo, in local split-screen co-op, or online with a friend. Those looking for more online action can also take on the "Free-for-All," "Demolition," "Domination," "Search & Destroy," "Capture the Flag," and "Team Deathmatch" multiplayer modes.

The much-lauded RPG-like system of doling out experience points and unlockable rewards returns in Modern Warfare 2's multiplayer modes, but Infinity Ward has also included a number of new wrinkles to spice up the action. Maps are designed to be both more expansive and more vertical; weapons feature a variety of new attachments; new "Pro Perks" let players gain more stopping power, greater speed, or automatic health boosts; and gamers who manage to string together a number of kills gain access to the new "killstreaks" system, which lets them call for seven different kinds of heavy-duty support, including supply drops, helicopter gun attacks, and unmanned aerial vehicle strikes. ~ Christopher Brown, All Game Guide

Single-handedly take out well-guarded targets through a combination of stealth and acrobatic maneuvers in this anticipated sequel to 2007's Assassin's Creed. Featuring a new protagonist in a different era, you'll control a young nobleman named Ezio Auditore da Firenze in 15th century Italy, at the height of the Renaissance. After a tragic event befalls his family, Ezio trains to become a master assassin, looking to exact his revenge on those responsible. Ezio will explore three sprawling cities, countryside, and various small villages while completing objectives during the day or at night. Assassin's Creed II offers three times the mission types found in its predecessor, with more things to see and do within each setting.

Money is now an important part of the game, allowing Ezio to purchase weapons, clothing, armor, repairs, and decorative items for his Italian villa. Ezio can pickpocket people, search for hidden chests, and complete side missions to fill his coffers. Other key changes include Ezio's ability to swim and even soar through the sky thanks to friend Leonardo da Vinci's flying machine. The open-ended world also allows for more free-running, climbing, and leaping from great heights. Among the new weapons at Ezio's disposal are pikes, maces, war hammers, scimitars, axes, and twin wrist-mounted blades that can be used to kill two people at once. Updated combat techniques include the ability to grab, kick, head-butt, drown, disarm, or pounce on enemies. ~ Scott Alan Marriott, All Game Guide

Set on the fantastical sci-fi planet of Pandora, James Cameron's Avatar: The Game is a third-person adventure with RPG-style character development, featuring predominant shooting and melee combat action. The game's story poses challenges to the player's moral perspectives, as well. A prequel to the movie, set two years earlier, Avatar: The Game follows its own original storyline. Humans have come to the planet to harvest valuable minerals. They find themselves at war with the dominant native species, the Na'vi, a humanoid race of great size and strength but only stone age technological development. The futuristic humans have developed a method by which they can remotely take control of a mindless, genetically engineered Na'vi body, and experience existence through this avatar.

Players take the role of a character named Able Ryder, who is a signals specialist soldier with the human Resource Development Agency, or "RDA." From mission to mission, the game moves from Ryder's experiences as a human soldier, and those in the role of a Na'vi avatar. Players can chose their character's gender and customize appearance, and add skills and abilities as they gain experience and power by progressing through the adventure. They will eventually face a crucial choice, similar to that of Jake Sully in the film: To remain loyal to the RDA, and lead the human forces to claim control of the planet, or to assume the identity of their avatar and side with the Na'vi, leading the native people to expel the invading humans from their sacred grounds.

As a human soldier, the game plays like a 3D third-person shooter. Players have access to high-tech weapons and equipment to help them survive in the brutal environments of Pandora, where hungry, dinosaur-sized creatures hunt and lurk all throughout the surreal wilderness. Humans can also use vehicles, including large, heavily armed, walking mech suits that are more than a match to the sheer physical strength of the towering natives. In the role of Ryder's ten-foot tall Na'vi avatar, players excel in melee combat, swinging a mighty battle staff, and gain expertise with a (truly) long bow as well. Na'vi also have all the advantages of a native people, and even the indigenous creatures may come to their aid, if properly coaxed.

As in special theater screenings of the film, Avatar: The Game can be played with stereoscopic three-dimensional display, using televisions and polarized viewing glasses that support the contemporarily cutting-edge technology. In the standard visual mode, the game runs on any TV that works with the console. ~ T.J. Deci, All Game Guide

Based on former U.S. Navy SEAL Dick Marcinko's book series, Rogue Warrior is a first-person shooter with an emphasis on tactical warfare and real-world combat scenarios. Players take control of Marcinko himself in a series of covert missions set behind enemy lines in North Korea. The object is to lead a SEAL team safely across North Korea's shipyards, prison camps, submarine pens, and other locales to return back to South Korea. Designed using Unreal 3 technology, Rogue Warrior offers multiple ways to complete objectives by featuring wide-open environments and dynamically changing events. Ten multiplayer modes are included with a choice of more than 200 day and night maps, while the main campaign can be completed alone or cooperatively with a group of up to four players. The latter option lets friends drop out or join in at any time without requiring the rest of the group to pause the game or to save progress. ~ Scott Alan Marriott, All Game Guide

The first video game based on the Bakugan license combines the action of the collectible card game with a storyline penned by writers of the animated series. Players will engage rivals in a series of battles to develop their unseasoned Bakugan brawler into a fierce competitor. The action first involves throwing Bakugan cards onto the ground before tossing a Bakugan ball toward them. When two balls land on the same card, they will transform into powerful monsters that will fight over the card. Bakugan Battle Brawlers offers an assortment of distinctive battle arenas, featuring various shapes, sizes, traps, and other distinguishing elements. Forty Bakugan are available to collect and defeat, with hundreds of cards included to fine-tune strategies. Battle the computer or challenge friends to a multiplayer match with custom rules. ~ Scott Alan Marriott, All Game Guide
