I have an idea.How about a huge zombie swarm marches through the city and we all get flushed out into the open. or a flood or something like that that would make us leave hideouts etc.

I like the zombie horde idea, it'd give all of our characters a reason to work together and form a bond. It might work better shortly after they've all met instead of being how they meet... I dunno... it's up to Sarge.
