VS has no feelz. You should make your dorky guy-who-wears-skin-tight-black-cat-suit game like L4D. Make him have to kill zombies in a swamp with several characters who always have witty responses.
Then I might buy your "lame, sneak-around-in-the-dark-and-AVOID-combat" game.
yeah I said it, he reminds me of catwoman.
