Early on, your chosen character runs into a vampire hunter while trying to feed. He prevails, but finds a photo of a fellow vampire Kassandra on his body, with her details and address. He goes to check on her, but is too late: however, he finds the sparse clues she learned about the vampire-hunting cult Erevos, before they arrived to claim her life. From then on, your character devotes themselves to eradicating the group before they fall prey to it themselves.
The game is mostly remembered today for its one fourth wall-breaking feature, where the In-Universe Game Clock was the same as your system clock. This meant that you literally couldn't play the game during daytime, unless you changed your system time - otherwise, the game simply showed you the image above.
Tropes present in Erevos:
- Ancient Order of Protectors: Erevos were first formed in rural France in XII century, after a woman and her child were found drained of their blood and with neck wounds. When the local lord responded by burning an obvious scapegoat, the relatives of the victims decided to take matters into their own hands.
- Antagonist Title: Erevos is the name of the vampire hunter outfit who are your sworn enemies.
- Asshole Victim: While playing the game as Eric, the first you see of Kassandra is her breaking into your house, and feasting on the human Eric locked up in a room earlier on. She simply apologizes for depriving you of a future snack, with about as much emotion as if she's had pinched a cookie from a jar.
- Ax-Crazy: The background entry for Eric Kolprot states that he doesn't just feast on the people to survive, but literally butchers his victims because he enjoys the smell of blood and flesh. He even literally uses an axe on his hunts, in contrast to Giannos' katana.
- An Axe to Grind: Eric's Weapon of Choice.
- Cool Shades: Giannos wears these on his portrait.
- Hero Antagonist: The vampire hunters of Erevos.
- Infant Immortality: Averted in one disturbing mission, where your goal is to steal a baby from the hospital for one of the ancient vampire leaders. The newspaper clipping you find later on shows the gruesome aftermath.
- Katanas Are Just Better: Giannos lived in Japan, which is where he got turned. He learned to wield a katana there, and still carries it to his day, which is what he uses to hunt his victims.
- Our Vampires Are Different: Here, they are not affected by garlic at all, but sunlight burns them really well, to the point you can't even play the game at daytime. Moreover, they may shrug off normal bullets, but explosive ones are beyond their Healing Factor, so the hunters of Erevos mainly rely on firearms, and save stakes for close-quarters engagements. Erevos' notes also reveal that while they have the classic fangs and talon-like nails, their heart still beats, though in a completely regular pattern that's unlike that of any human.
- Regenerating Health: Inverted; your health, represented by the "Blood" meter, steadily ticks down throughout each mission.
- Villain Protagonist: You are a vampire and intend to kill all the vampire hunters. While they want to do the same to your kind, they have good reason for that, as none of your kind are Friendly Neighbourhood Vampires - just check some of the entries above. While Giannos has a more sympathetic backstory than Eric, he still left a trail of dead bodies over the course of his lifespan and needs to do the same abhorrent actions to prevail.
- Voluntary Shapeshifting: Both of the playable characters can shapeshift: Eric into a bat, and Giannos into a crow. Kassandra was apparently capable of transforming into a black cat, or shrinking herself to appear as a little girl.
