The Adrenaline Vault previews Requiem: Avenging Angel looking at this shooter from 3DO/Cyclone Studios that just went gold. Here's a bit from the preview on what Requiem is about:

Borrowing heavily from these words and others like it, 3DO and Cyclone Studios are almost ready to bring Heaven and Hell to your computer screen like you've never seen or heard before. Requiem: Avenging Angel relies heavily on non-player character interaction to develop its multi-layered storyline much the same way Half-Life does. The game is a three dimensional action shooter with fiction that combines the prophecies of ancient religious texts and includes a script right out of the movie Spawn. Requiem is truly a religion all its own.
