You know what would be good? If it took a random picture off some website like Flickr or something and displayed it. After a certain amount of refreshes, you could set tags.
Features this game needs;
Surviver groups,
ammo,
scavenging,
melee (but only as last resort),
slow fat people (boomer anyone?),
zombie groans (zombies groan when sighting a human, attracting nearby zombies),
option to play on a animated map or something,
places where humans or zombies can't walk (STOP WALKING ON TOP OF TREES, DAMN THEE!),
the ability to have more then just a few thousand zombies attacking.
The idiots in this game depress me. Someone just did a caption of "wtf this game is gay", another "the f***s an ombibus" and another "you can tell that guy is gay"
