One of the many things that I liked from Fall Out 4 was the unique/ legendary items that dropped from unique enemies that you can find as you wandered through the waste land. The other day when I was playing 7 days to die I cleared Butcher Pete's poi and right after cleared the farmer poi that had the unique boar Grace. Then I thought about what and who Butch Pete was and created a simple drawing of what I thought he might look like.
Personally I would love to fight some unique enemies that are associated with Poi's and only Poi's. They wouldn't show up outside of their respective place. Obviously with The Fun Pimps team putting out new HD zombies I am sure they already have enough to do along with Bandits but I would hope that this would be far down the road content. Right above the picture I put an idea of how the unique weapon, which would be Pete's cleaver, could work along a kind of background story to it. Also should make note that Pete would be a unique zombie.
All in all I feel that it would add a lot of interesting paths to the game. For example the Traders could give you this quest saying something like "This unique zombie has been creating a problem. Kill it and I will reward you". Adding to skill tree builds, for example Pete's cleaver would count as a blade working for the agility tree. Finally this could allow the option to add weapons with out messing up the skill tree. I personally really wanted a Katana added to knifes ability but that won't happen now though skill trees but a unique zombie say a Japanese Soldier at the bottom of Red Mesa could drop a Katana.
Maybe this could be a thing or not but I would love to have it in game. I know it's probably now on the road map for TFP or maybe they already had a plan with special infected that I am unaware of this is just my thoughts and ideas.
Pete's Cleaver: A nasty looking object. Looking at it it is covered in blood and the blade is so worn and splintered you find it hard Pete was still using it up to this day. Thankfully most of his recent victims have been zombies. Picking it up it feels cold and you feel the pretense of hundreds of antagonizing souls that were victims to the cleaver. The weapon despite its looks is still deadly and cuts though most things with easy.
Bonus Stats: This weapon counts as a blade. Extra Bleeding, Armor Penetration (Or something like that).
