I can't figure how to quickly dispatch zombies using blunt weapons, it appears that there is no way to tell if your hitting them in the head. Hitting them in the head is supposed to kill them faster, I ususally end up bashing them repeatedly for about 2 minutes before they die. Any good tips for braining a zombie?
To hit them in the head, I have to aim so that the center of my screen is about two zombie-heads to the up and right of their head (yes, it feels like a lot).
You can tell where you're hitting by watching where the blood comes out. If it's coming out of their body, you're aiming too low :)
Hit them in the head.
This is more difficult than you would expect, however. The hitbox is extremely strange, and pointing at the head typically hits the zombie in the chest. When standing on objects, such as cars, the inaccuracy of the hitbox seems to be even higher.
Gauge your accuracy by watching for blood splatter and zombie response.
