Hello every one I am here with a guide for the achievement Undead Head Harvester!
This achievement is simply earned by only getting head shots from the begging of the game. Simply take your starting pistol and progress through the ship making sure to shoot twice at every normal "Skinny" zombie, and Four times for the larger "heavy" zombies. Crawling zombies are easy to take out with a crouching shot.
Take it slow and steady if I recall there are over 25 zombies in the beginning of the game so even though you have Infinite ammo keep your shots accurate. (Even though it's near impossible to miss)
The only trouble I ran into was : the "Heavy" running at me, but simple enough again just stand still and hit
4 Times and his head will pop, and the broken stairs (just jump down on normal or easy and you can just spam
and kill all 4 at the bottom.
TL;DR? Watch This
