L4D3 should have:
Some emo dude.
A fat chick.
Another black guy.
A christian.
That way, the only likable character is the black guy unless you're tribal, and to the very few who actually believe (lol flame war), the christian.
But you gotta make the christian stupid and have big ears.
Two new zombies.
One that is just like the hunter and jockey, except that he jumps an even shorter distance than the jockey, but can spit needles as he rides the player.
One that can steal med kits and run away.
Oh, and more weapons that are the exact same.
