You can get it on Xbox, PS4, or PC. I got mine for the PC from Steam. I have to say, I greatly enjoyed the game.
It takes place in London in 1918 during the Spanish Flu epidemic. You're Dr. Jonathan Reid, a notable doctor and blood specialist who has developed a new technique for blood transfusions. The game starts with you waking up in a mass grave, everything is hazy, and you soon discover after killing the first person you come across because of your unbearable thirst that you're a vampire. Throughout the game, you try to find out who it is that made you a vampire and why they just left you. You befriend the administrator of a local hospital, and being a doctor, you work there to keep the local population healthy. There's outbreaks though of creatures called "skalls" that are related to vampires, and you're trying to figure out why they're becoming such a problem.
The voice acting is top-notch in this game. The various accents properly denote the class of the people you interact with. More refined people have a much more dignified and reserved manner of speech, and the lower-class people have accents and vocabulary typical of the working-class people.
The game is unusual in that you can't save the game as you progress through it. You pick out a slot at the beginning and throughout the game, your progress is automatically saved. Any decision or action you make is one you'll have to live with. There is also no difficulty level. How hard it is depends on how you play it. If you feast on civilians, you get more experience and can access higher-level skills. If you want to be a good little vampire, you can make sure most or all of the people stay alive (you get some experience for curing them of their ailments), but you don't get the experience and later levels are harder. But every citizen has their own story and their own quest and social circle. You kill one, and you close off some interesting story quests. Associates of that person you kill will also be affected, and you may close off their quests and story as well. Also, if you don't cure people of their ailments, they can die, and if enough people die, a whole section of the city goes to ruin as everyone goes into hiding, you lose all quests there, and the streets become filled with vampire hunters and monsters.
The difficulty gets weird though. I played as a good vampire and didn't kill anyone. It was VERY hard to progress through some levels. The monsters and vampire hunters I'd come across trying to get to a boss were so high above me that I'd have to try a dozen times before I'd make it to the boss. But then I'd find the boss only moderately challenging.
Still, the story, ambiance, and voice acting were VERY nice. And the main character is rather nice to look at. He's tall, thin, bearded, with a hawkish nose and hard angles and dark looks. I like that appearance. And his voice acting was PERFECT!!!
If you're looking for a different experience, this is one to check out. It's not like the big-budget AAA games, but the developer knew it couldn't be and put a LOT of effort into making the characters very compelling. And they succeeded.
