Rather than simply jump right into the middle of the action, GameSpy figured that they would start from the beginning, as this would give them a good chance to focus on the game's storyline a bit. Of course, before you start to play you'll need to decide which mercenary you'll be. As in the first game, you'll have the option to pick one of three characters, each of which brings a different style of play to the action.
Mattias (voiced by the always-excellent Peter Stormare) is the fastest, making him perfect for quick-strike attacks, while Jennifer Mui can be used to approach a situation more quietly. Finally, there's Christopher Jacob, the tank of the bunch. GameSpy don't know yet if one character's campaign is easier or harder than another, but it seems like you can't go wrong with any of them.
