Batman has obviously been influenced by the pulp heroes, so it's nice to see a mash-up series where Batman and the Shadow can clash. I wouldn't say team-up, since these two are not the sort - unless it would involve the likes of Ra's Al Ghul.
As you can see in the art below, there's a lot of fighting. I am in between on the concept of it (though I love the artwork), since I'm a fan of the creepy/cheesy Kyle Baker Shadow era. The idea that the only thing you hear is the laughter and see are the muzzle flashes makes it much better.
