I'm assuming you're pointing out similarities to Left 4 Dead characters. Yes, it is quite creepy.

the characters were *crag*ing modeled after these guys, it says in the credits

I'm *crag*ing aware of that. Where do you think I got these pictures from?

Boreale makes it look like just a coincidence.

I actually don't see the resemblance in the dude that's supposed to be Ellis.

i kinda do.

Go look up the bigger picture on the Left 4 Dead wiki. The only one's I couldn't see were Coach, Rochelle, and Zoey. They all had pretty bad pictures though.

yeah, the one who Zoey is modeled after does not look alike at all.

I liked Zoey better when she was based on Alesia Gladwell.
