This is a basic google map simulator with a bunch of animated people and zombies, but there are also a maximum of 8 cops you can add and change certain options like...
(All of these are done at re-infection)
starting zombies
starting civies
starting cops (8 tops)
Armed civilian %
civilian accuracy %
Cop accuracy %
infection time (as in how long it takes an expired body to rise)
zombie speed
and zombie spawn direction (N,S,E,W)
It's pretty hilarious to watch a humoungous hoard of zombies close in on a shooting cop so slowly.
