A few faults, but great overall. Read on...
The game really needs jets and parachutes, like BF2. I'm very sure though, that BF:BC2 will greatly improve on these areas.
Don't be disappointed after reading that. Those problems are small and don't really wreck the game. It has a very funny and clever campaign and the characters have great lines. The multiplayer is brilliant, it has gold rush - a new mode, and conquest - the traditional BF mode. But the best thing about the game is the Frostbite Engine. It allows you to destroy literally everything you see.
So if you're planning on buying an FPS, get Battlefield: Bad Company!!!!!!!!!!
