In Vox Populi, Vox Dei (A Werewolf Thriller), you move through a series of one-screen platform scenarios, alternately slaughtering and sneaking past the werewolves you encounter. The slaughter is satisfying and brutal, initiated via an impressive crouch-jump manoeuvre and finished off with some spacebar-mashing as you claw your pinned victim to shreds.
The sneaking is less satisfying, but also less frequent. On balance though, this is lots of fun.
