The original Gears of War became an action genre classic thanks to its incredible graphics, cinematic presentation, and solid cover system. The sequel repeats this formula, and though it introduces new weapons, enemies, and environments, it remains an incredible yet familiar experience. The 10-hour campaign is rambunctiously entertaining, with clever set pieces and epic confrontations that punctuate the exhilarating stop-and-pop gunplay. The multiplayer offers more significant upgrades, with four new modes, 10 new maps, and support for up to 10 players instead of eight. These things make for a package with significant longevity, and though Gears of War 2 ultimately refines more than it innovates, it still deserves a place in any action fan's collection.
Gears of War 2 picks up the story six months after the end of the first game. The Locust are so powerful that they can sink entire cities from below, whereas the humans are becoming even more desperate thanks to the spread of a disease called rust lung. With fears that the last city of Jacinto might fall, it's down to Marcus Fenix and Dominic Santiago to take the fight to the Locust in a desperate last stand against their alien foes. Survival is at the centre of Gears 2, but there's also personal drama, with themes such as family, death, and even love interwoven into the grand plot. This sheds some light on the characters and the universe, and though it ultimately uncovers more questions than it answers, the game has a much grander premise than its predecessor.
