Bushes count as cover, making forests the best place to sneak attack.

It drains stamina, adding difficulty if fitness level is low.
Knocked out targets can be bludgeoned or assassinated afterwards.
Knocked out targets can be picked up and looted.
Zombies can be knocked out too with the same options.
If armed with a blunt weapon, it will automatically unequip your weapon and switch to unarmed.

It's less stamina taxing then choke holds.
Possible with sharp weapons.
Kills the target in one hit.
Possible on white zombies.
Very effective against zombies due to their inablity to hear well.

I cannot confirm if rain or shadows work as cover due to the difficulty testing it.
While i tried to choke white zombies it cancelled my attempt, making me believe it's impossible.
