With rampant cheating, broken leader boards, and poorly balanced weapons, the rough launch of Call of Duty: Modern Warfare 2’s multiplayer mode sent some virtual soldiers AWOL. Bad Company 2 gives those mercenaries a new home. Melding its signature destructible environments with large, open maps and firepower-happy vehicles like choppers and tanks, Battlefield stresses tactics and teamwork over the haphazard running and gunning of its competitor. The popular Rush mode, which pits two teams against each other on an ever-shifting battlefield, is our favorite. Four-player teams can also tackle two new squad-based modes. Or you can go it alone in the new single-player campaign that finds the misfit B Company running, guns blazing, across the globe.
