If you have a PlayStation 2 and never played Hitman before, you suck.
You can execute the missions like you want (unlike Metal Gear), and the most perfect part is the fact that you can stole the victms clothes (not all of them but some of them...).
There's a very funny video in the YouTube teaching how to complete H-BM in a insane way, made by a guy called Ebeeto.
The graphics are good and everything is good in this game, exceot the space that it requires in the Memory Card, 2GB and some more. This is just crazy!
But no grade 10, because there's a lot of big bugs, like the "Duck Bug". Read the example below to execute the "Duck Bug":
eg.:In the "Flatline" stage, take the cement way 'till you find a smoking guy, take him as hostage, got to the board of the place that his smoking (the place with two benches and the admission paper) and do a "Drop Body", then TA-DAA, the "Duck Bug". now that you did the "Duck Bug" only you analogic stick works, the rest of the button are hmm...uh...hmm...sleeping...
