Trust is a vampire FPS with immersive sim elements from the Forgive Me Father devs
In theory, vampires and immersive sims go together as naturally as bats and caves. Immersive sims tend to involve a balance of stealth, acrobatics, raw strength and crafty manipulation, and vampires are celebrated for all of these things. Despite this, actual vampire-themed immersive sims are rare. My list starts with Vampire: the Masquerade: Bloodlines... and sort of ends there. In a devastating betrayal, Arkane Austin's Redfall wasn't an immersive sim but an open world co-op shooter (a not very good one). The much-delayed Bloodlines 2 was recently downgraded from immersive sim to RPG by new developers The Chinese Room. Arkane Lyon's Blade adaptation seems promising, but it's a ways off.
