Hitman Sniper Challenge - recheck

Hitman Sniper Challenge (PC, PS3, X360)
in case someone missed my previous post, this is an mini game you get for pre-ordering the new hitman game.
I will review it as mini game, and that mean i won't hold against it its short length, lack of story or unvaried gameplay. it does exactly one thing, and it does it well.

Story 0.5/1.
almost non-existent, but neither is needed.
You play as Agent 47 and your task is to kill the CEO of an weapon company and as much as possible of his 14 bodyguards to "send an message". end of story.

Graphics 2/2.
typical modern good-looking graphics.

Gameplay 3/4. (polarization -2).
if you'll give it -2 here, you have nothing to do here. there isn't anything else in the game.
you are going to kill your targets with an sniper rifle. no other options. the question is how are you going to do this.
the first attempt of most people is just shoot the main target right when he shows up and then try to kill as much as possible of the guards.
this won't get you very far because the guards will leave the scene very quickly after his death.
then you'll start devising strategies on the best way to do it without rising an alarm.
you'll study their patterns and you it to your advantage.
you'll kill them in the exactly right moment that will cause their body to fall in such way, that it won't be seen by others.
you'll hide them in pools, bushes and down on the streets below. (according to the game, the streets are empty at that time of the day.... yeah.. sure..)

Replayability 2/3. (polarization, if you hate the gameplay, you won't want to replay it)
each attempt of the poor CEO's life takes about 6 to 10 minutes. and you'll be doing it again, and again, and again...
each time aiming either for higher score or to complete challenges.
once you complete a challenge, it will stay challenged in all your next attempts and will give you bonus score.
so what is so important with the score? well obviously it is for barging rights.
my current high score is something like 1.7 million.
but furthermore, all the score you gain in all your attempts is accumulates and used to unlock improvements for your rifle.
those improvements will not only help you get even higher score, but will also stay unlocked in the main hitman game (you brought it as well, remember?).

final score: it's an sniper simulator. if you'll like it then you'll rate it 7.5/10.
if you'll hate it.. well then there is nothing to talk about.
