The Hitman series is one that I've played and loved for about 15 years and the 2006 entry Hitman: Blood Money specifically is one of my favourite games of all time.
The series has always been about the creative kills; drop a piano on an unsuspecting criminal, poison the mob boss’ morning gin, dress up as a clown and beat a villain to death with a frying pan at his child's birthday party etc.
It’s a series about creativity, of how cunning or sadistic can you be? My strategy would always be - try to plan something clever. Fail. Panic, ending up with bursting into a room, shooting the target and then hiding in the nearest bin.
