RockGame announces Vampire Clans, an action/RPG based on the vampire mythos coming to Steam "when the night come." This uses a side-scrolling POV and includes the construction of your own elaborate vampire lair beneath the streets of Paris. Here's a bloody trailer with a look at how this works, and here is a fuller explanation:

Become the most powerful vampire lord and lead your clan to take over Paris underground. Expand your base, collect blood and kill anybody you want.

As a vampire, you have to enslave people and drain their blood to keep alive your clan. Build prison and go hunting, fresh blood is the most important thing for vampires.

Vampires are super fast. Use this advantage in smooth, slow motion fights. Use magic, alchemy, weapons and special abilities to beat your enemies. Conquer other clans and enlist their members ... or kill them, the choice is yours.

Train your vampires to create the best formation to fight against your enemies. Evolve from cave vampires to the most powerful vampire lords.
