As much as I'd like to see a Delta Green based action CRPG, having an M-60/plasma grenade launcher in a story based on "The Outsider" would deduct from the threat the player would feel from the antagonists.
Videos of ANY horror game really doesn't convey what it's like to play yourself.
This game is scary, but oddly it's a lot scarier once you turn the sanity effects off. It's just too off putting to have my character gasping at everything; it's the horror equivalent of a laugh track.
