Blood is the first shooter of its kind that was created using high-quality voxel graphics. The player will have to fight the dark minions of the evil deity in order to take revenge on them for what they did to him and his family. There is no longer any pity or honesty left in him, the man is ready to commit any sin or crime, because his relatives cannot be returned.

The action takes place in an alternative world, similar to the United States of the 20th century. The main character Caleb took part in the civil war and in 7 years managed to receive the title of a ruthless shooter and fully justify it. But after the end of the fighting, he returned home, where he met the beautiful Ophelia, whom he would later marry. From her he learns about the existence of a religious cult, which they join together. The priests worship Chernobog, who after some time begins to notice that the protagonist is gaining more and more influence among his minions. To get rid of his competitor, he orders his death. But 20 years after his death, he rises again as a living dead man with an uncontrollable thirst for revenge.

Despite the fact that the main character Blood is already a non-living creature, he should still take care of his health. After all, monsters can deprive him of the ability to move, and then this will be tantamount to loss and eternal torment. Therefore, when fighting enemies, it is necessary to draw up thoughtful tactics and, first of all, in battles with bosses, understand their behavior.
