Okay, I bought the game and I've played around for some hours.
The storyline is pretty simple, basically a "pure" vampire was born at some point and then they took over the world, treating humans as lesser beings. Then, after a while, a new breed was born, the half-humans/vampires, and they created a guild that's trying to liberate the world from vampire rule. There's a lot more to it but that's the gist of it.
There's a map of Paris from where you can select different spots to visit, and in these spots you can walk around and explore the city. In these explorable fields there's NPCs and items to be found, as you'd expect in an RPG, but they're also populated by other vampire hunters i.e. other people who're playing the game. If you approach them you can make a "bloodbond", which is basically adding them to your "friend list".
All that comes into play in the battle system, because when you go on a hunt/mission, you gotta make a party. The game retrieves a list of random players that are more or less around the same level as you are so you can bring them to battle with you, and if you bonded with someone there's a higher chance of them appearing in said list.
After choosing your partners you go and battle the vampires in a very Infinity Blade-y fashion (tap to attack, swipe to dodge, dodging at the right time leaves the enemy open to your attacks) where generally you start out fighting the vampire's human form, and after depleting their HP born, they're reborn as a stronger, evil-er true vampire, and after depleting that HP gauge you finally kill them by putting a stake through their heart. Before starting a mission you select which stake to use, it can be either a gold, silver or wood stake, and each one yields a better chance of getting rarer items from a mission. You have an infinite supply of wood stakes, which give you the worst items, but to get the silver and gold ones you gotta purchase them with either real money via IAP or the game's currency. The game also has a "clan" system, each clan is basically an element and exploiting the enemy's clan's weakness can help a lot during battles, luckily you can switch your own clan at will and level each up to be used when the time is right.
Battles are timed, generally you're given 3 minutes to complete it, and if time runs out you gotta either start the whole battle over and lose whatever items you earned, or add more time using premium items. The same thing happens if you die, you either lose all and start over the battle or you use a premium item to give you a second chance.
On Paris' map you can see which spots have quests for you to take, there's missions, which are the ones that advance the storyline, and hunts, which are just side quests. Generally the game flow goes like this:
finish story mission -> new items on the shop and new quests pop up -> choose to undertake story mission -> cutscenes -> vampire battle -> finish story mission
I'm not too far into the game but I already find it repetitive.
Graphically the game is gorgeous, playing on an iPad mini and it runs at anywhere from 30 to 60 FPS, it's not locked. I imagine on a new iPad or an iPhone 5 it must run at 60 FPS all the time.
The music is nice, and the art direction is superb; you can tell the dev team spent a lot of time trying to recreate that European city feel.
All in all, I'm a bit disappointed because of how repetitive the game is, and also the difficulty level is a bit odd, I seem to either have a lot of trouble with the enemies or kill them really easily, though that may also be because I'm not very good at these... action-y games. I'll continue playing and see how it turns out.
Fake edit: I forgot to mention some things that I thought were very peculiar:
-The game has a share button like the one you find on iOS or OSX 10.8 for everything, you can tweet a screenshot of the game at almost any point with it.
-The control method for fields is super odd, you can tap anywhere on the screen and move your finger around to change the camera's position, but to move you gotta tap and hold in the direction you wanna go, takes a bit to get used to.
Finally, screenshots!
