First and foremost let me mention that I don't like the release module used for this game, I don't think that a Hitman game should be released in an episodic format especially considering that it breaks immersion and pacing, and also that the consumer would be paying for an unfinished product is something that I personally tend to not support. As a result I refused to purchase the game until it was complete and I would only purchase it during a very reasonable sale, with all of this out of the way let me say what I actually think of the game.
I liked Hitman, there isnt any two ways to go about it. The game is very enjoyable and overall pretty well put toghether (not flawless though), there are a ton of different ways that you can complete a mission which adds to replayability and that is good however it doesn't justify an episodic release since replaying the same level over and over again without going through the entire game first can be pretty boring. This leads to a big issue caused by the episodic style release, that is that after every mission I have to go back to the main screen in order to go to the next mission and I feel that by doing that it breaks my immersion a bit.
Voice acting is top notch and the soundtrack although to me not memorable blends well with the game's environment. The gameplay is pretty solid although when you knock out a character and want to drag him and if there are a few items lying around the KO'd character it can be a pain to get the drag prompt to appear, this becomes annoying especially if you are in a hurry because a NPC is coming towards the room you are in and you need to desperately hide the body.
I would of liked Agent 47 to have a bit more of variattion in his moveset, for example if you takedown an enemy next to a container he could chuck him inside it as part of the takedown, it would be a pretty cool way to use the enviornment to hide away bodies in a quick and efficient manner. It would of been nice if you could walk up to a character while concealing your gun behind your back since it is something I picture an assassin doing. Looking at current game technology it does feel like the combat mechanics weren't as refinned as they could of been.
I feel like levels are a bit too small in scale, at times I would of liked to have a slighly larger environment to play around in and be a bit more constructive with how I could take out my target. Although not really that big of an issue but with only 6 levels the game left me wishing for a bit more at the end.
In my opinion the weakest part of the game is the story, it doesn't connect too well with the gameplay part and feels very disjointed and feels more like padding than something necessary. You could remove the entire plot from the game and get the exact same experience, which is a shame since I like a good narrative in a game, also story doen't answer any questions at it's conclusion and only raises even more. The game is obviously following a TV season style of storytelling but here is something the game does wrong, a season finale normally answers most if not all of the season's questions while raising new important ones and Hitman fails terribly at that.
Overall it's a fun although slightly flawed game, I would recommend it to anyone but not as a full priced game since it does feel a little bit lacking so I would recommend to pick it up during a sale.
