I'm guessing you didn't play the game? Spoilers in white.
How come, got so many bald guys??
Ans: They are fellow clones of 47. 47 is a clone bred and raised to
be an assassin and is deemed the most perfect specimen created for
that purpose.
the dead person in the office isit 47??
Ans: No he isn't. The dead guy that was shown to the detective at
the end of the movie was just a scapegoat that 47 presented to the
detective. This was so that the detective would have evidence to
his superiors that the 'ghost' was finally eliminated. But of
course, the real 47 is alive and well.
the person whom the detective has been chasing??
Ans: duh... 47
then the bald guy is another 47?
Ans: Uh... which bald guy you referring to? Anyway there is only
one 47. The rest of the clones had other numbers.
who is the real 47??
Ans: As long as you see Timothy Olyphant's face on the character,
he is 47. Even though there were hitman clones everywhere, their
faces aren't identical to one another (in the movie, that
is).
then in the end, the sniper, who is the dead person the bald
guy??
Ans: Probably another hitman, judging by the dressing sense (red
tie, black suit)
i thought 47 got killed by the detective??
Ans: Errr... no. Where'd you get the idea he was killed? 47 wasn't
killed, he merely got caught by the authorities and was escorted
off in a police car until Agent Smith gave him a chance to escape.
You saw that part... right?
So in the end wad happen to 47??
Ans: Alive and well.
