Okay, first thing's first, I'll give it Spoony for helping me out here by summing up my opinion on this travesty.
Why is this a betrayal? Oh my poor ignorant fools, I shall tell you why.
This is NOT what Hitman is about. The Hitman games have always been about cold, calculated kills there is none of this Die Hard style shoot-'em-up, outdated 80's movie bullshit in the games. The game actively penalized you if you so much as thought about taking out an M16. Sure, it gave you the option but if you have to use a gun AT ALL then you're clearly not smart enough to play the game as it's meant to be played.
Hitman is about patience and studying your target, it's about planning your actions and forming a strategy in order to take out the mark without anyone even knowing what happened or even think that it was because someone actually did it. Y'know, like a real professional killer and not some dime-a-dozen murderer.
Every mission in the series was set up so you can make every death look like an accident so nobody would even suspect that you were ever there. It is entirely possible (and advised) to go into every mission with nothing more than the syringes, the fiber wire and a couple of bombs, that's literally all you need.
Anyone who's played the previous games knows that it's about stealth first and that includes how you take out your targets, it's more a puzzle game than an action game because you're supposed to look at what's in the environment and then figure out how you can use it. Like when you swapped the fake gun for a real one to take out an overacting stage performer before detonating a bomb to drop a chandelier onto his lover's head as he rushes out to see what's wrong with his boyfriend. The whole thing will look like an accident.
They don't show you the newspapers for no reason, it's to show you if anyone is onto you and how long it'll be before they come to catch you, if you did everything correctly and made it look like an accident then you wouldn't even be mentioned in the papers, it would just be another "tragic accident". That's what a professional killer does, THAT'S WHY YOU GET PAID FOR THIS SHIT, because there's absolutely no way it's going to get linked back to your client if nobody suspects murder, is there?
Also this Batman vision bullshit, what is this? Why is it here? What happened to my map? Why are the patrol paths of every NPC mapped out like a fucking paint-by-numbers colouring book? How does that even fucking work? Do you know how absolutely offensive that is? This is two great big middle fingers right up the ass to every player who felt the rush of sneaking up behind a bodyguard or target that you need out of the way. Everyone of us who slowly crept up behind them with the fiber wire at the ready chanting "please don't turn around, please don't turn around" over and over in our heads and adding a massive amount of tension to the missions.
Now what have we got? We've got a diluted version where we don't even have to make any effort to take someone out, which also means that it's actually ENCOURAGED that you take out innocent people with nothing to do with the intended target. In the old games you didn't do this because you wanted to, it was a last resort, if you could you'd avoid it as much as possible. In this version you're pretty much told to strangle any fucker just because they're there.
In the old games it's a bad thing to take out non-essential people because not only are they just the average working Joe Nobody who you've not been hired to take out, but more importantly: they're also a liability.
Every body you stash in a dumpster or laundry chute is another piece of evidence that's going to harm your ability to do your job professionally, which as I've said, means that nobody suspects foul play. Who the hell's going to not think that the target was murdered when they find the chef's body crumpled up in the laundry room like an old sock? That not only makes you a bad Hitman and no better than a petty thug, it also means that your client will be under suspicion.
I don't care if everyone in the entire building is a Nazi, I'm not going to kill any one of them unless I seriously have to and if I do, I will have to restart the mission to try and get a perfect run. It was exciting to sneak up behind someone and Garrote them, I agree, but it's also completely wrong and even though a "Game Over" screen isn't flashing up on the screen you can still be damn sure that the moment you've got to take out a non-essential target then you've failed the mission. I'm not getting paid to kill the underlings and by-standers, I'm being paid to kill the mark, everything else is murder, the mark's just business.
So, yeah, this is a massive slap in the face for any fan of the original games. It's a complete betrayal of everything established beforehand and it's a massive dumbing down of what once was a very intelligent series of games.
Hitman, I am disappoint.
