Can we have more than one character? I imagine we can make another one if our character dies, but what about two at once? 

Also: Should I go ahead and my characters fighters? If it's anything like the game, with quests and stuff, we're just going to be smashing zombie heads in, right? Or is this more like the trailer? I was thinking of making my character a lawyer or something but someone like her would just stay inside a safe house instead of going out on zombie murder sprees with electrified baseball bats.

I know it's sandboxy. I guess I was just wondering if the RP won't be as fun if I'm not playing a character who can go out and kick some zombie ass to a limited degree.
