Blood Knights' vampire storyline comes to life through the heroes Jeremy and Alysa. As different as they are, they are bound by blood and have to fight together to survive. While Jeremy is a mighty warrior who is dual wielding increasingly powerful weapons and uses devastating attacks, Alysa uses crossbows, traps, bombs and special ammunition to eliminate her enemies from a distance. Both are able to use various vampiric abilities that become ever stronger and more and more impressive in the course of the game. Jeremy for example can pull huge groups of enemies towards him and unleash chaos upon them once they are in melee range.

Set in the mythical Middle Ages, the players will be able to control both Alysa and Jeremy in their cooperative quest for salvation, either in single player or co-op mode. The protagonists will encounter numerous enemies, avoid traps and fight and confront an impressive  (and sometimes sexy) array of bosses - each one requiring a unique strategy in order to be defeated. Rich treasure and rewards await those who against all odds are able to fight their way through the wide variety of settings/scenes.
