Trauma Center 2 has a storyline

Yeah, we know that all the other ones did too, but all we ever remember of the story for any Trauma Center game is "surgery happens." Some guys perform surgery on some other people, because they are sick or injured. Trauma Center 2 is no exception: Atlus has gone to the trouble of crafting a narrative for the surgery game, and we guarantee it'll stick in our minds as "a guy gets glass in his leg for some reason."

This latest entry takes place in a refugee camp in an African country called Costiga, where a civil war and an outbreak of disease have led to an overload of patients and a shortage of doctors. Derek Stiles and his nurse Angie Thompson are in the area doing research, and are contacted by a young surgeon named, uh, Adel Chilba (or something like that) to help. Or at least that's how we understand it based on the translation. The point is (and remains): surgery happens.
