Unlike later games where destruction was often scripted ("Levolution"), BFBC2 allowed players to level almost any structure on the map, fundamentally changing the tactical landscape as a match progressed.
If you're looking for information on how to play, system requirements, or perhaps where to find legitimate copies, I'd be happy to help with that.
: Unlike the self-serious Modern Warfare series of the time, Bad Company 2 focused on the humor and camaraderie of "B-Company," making the soldiers feel like people rather than just avatars.
