New sounds and eyes for Mr. Beret, he'll sound real mean and aggressive.
Mr. Sawyer can now drop down from ledges to pursue you, partially this was because he spawns in the chaingunner slot, meaning there's plenty of times where he spawns somewhere which is completely fucking useless for him, and he's just target practice for you. It's not flawless, because sometimes they're spawned in blocked off cages or windows, but it'll make him a LITTLE bit less crippled.
The other reason is that I wanted him to be more dangerous, he'll pursue you more aggressively this way.
Of course, this can mean that he can potentially fall down from some height, either down in a pit where he's possibly useless again (unless there's a reason to go down there), or he falls from a cliff far up above where you had no idea he was there, and he lands on your head with his chainsaw out of nowhere, but, eh, that's situational enough that I don't think it'd be a huge issue, and also, the latter is metal, so I think I'll let it fly.
