Yeah, that's the product all right!
When I read your above post i felt kinda stupid.
Then I read the WP-38 readme, and i felt even dumber--if that's possible.
So I dug into my runtime and damned if I couldn't find the hand poses for the WP-38.
So then I checked my download and it didn't contain any hand poses for that weapon, either.
Reckon I'll just have to PM Madd Matt and let him know that I'm missing a couple of files, darn it.
