Code Vein is the Dark Souls of 2003 anime music videos with nu-metal soundtracks. That may already be enough of a review for you. How anime is it, and how Dark Souls? Well, there are doors that only open from one direction so as to indicate a future shortcut you will unlock later in the level, and it takes twelve hours of playtime before encountering a female character simultaneously wearing both pants and a shirt. You can circle strafe around enemies and backstab them, and everyone in the game is a hot tortured science vampire whose melodramatic backstory is unveiled through crystals made out of blood.
