Upon close inspection of Shadow Man, I see a game that has a lot going for it. It is based on a dark and moody comic book and Acclaim has succeeded in bringing all of that into the game uncensored (anyone familiar Nintendo's censorship record can appreciate this as a huge accomplishment). To their credit, Acclaim pushed for and got a mature rating on this game. And after playing for only a short while, it is obvious that the rating is well deserved: Acclaim didn't hold back the adult content.
Through its splendid graphics, ominous audio, and its well-scripted and well-acted dialogue, Shadow Man delivers a package that's respectable to the over 18 age group (but not by much). There's still plenty of bloodletting and overt cussing, but the majority of it is done within the creative context of the game and doesn't feel overly abused or cheaply implemented.
