The trailer is narrated by the game's main character, who was previously revealed to be Jonathan E. Reid, a doctor and vampire. "Science has failed us," he says, before explaining that the flu epidemic has killed thousands in London.
"I have few allies, and even fewer options," he continues. "It's a war, and I have to fight to survive. My life has become a waking nightmare. I did not choose the thing I've become, but I can choose the lives I take."
His closing line sets up the decision-making element of Vampyr's gameplay, which developer Dontnod has used as a core part of its previous games, Life is Strange and Remember Me.
Vampyr is a role-playing game for set for release on Xbox One, PlayStation 4, and PC. It is being developed using Epic's Unreal Engine 4. It takes in 20th century Britain, at a time when a lethal Spanish Flu is tearing through the population and vampires stalk its denizens from the shadows.
Vampyr will be published by Focus Home Interactive in 2017. Check out some screenshots from the trailer above.
