Here's a good tip to kill many zombies around in the big city. Just park your car outside the entrance to the garage so that it can still get out of the zombies do not come in and you can shoot them. The zombies shoot back where you can take while still sometimes but you do not have to run away permanently. Sometimes bats and crows come from behind. Have fun.
