A note- at the end of the rock lake area, after you beat the giant squid lance comments that "Gunpowder doesn't ignite underwater." This is not entirely true. Just saying.
I do like the menus and stuff better than 2, but the physics are just too bad to really be qualified as a "physics based gun simulator." Still a pretty good game though.
