Short but really good map. It does a good job of depicting a mansion. Reminds me a lot of Duke3D-style maps.
Exploring it is fun and rewarded by finding non-combatants in compromising situations. And this is what I like the most about this map: I can kill the innocent bystanders, too. Oops :)
I really wouldn't mind more levels of this kind. Maybe the hitman could clear out an illegal casino next, or even a brothel.
