All zombie garments should behave as they would for the player character, in regard to armor. So if some chick has a kevlar vest and is getting a little chew happy on ya. You would have to get through that armor or land a shot else where on the zombie. Assuming this isn’t already implemented. I really don’t know.
edit:
Add back in explosive shotgun shells.
Also add in mods for some pistols to give those pistol semi/automatic fire options and features.
Combine a taser and a massager to craft the “Electric Boogaloo”
Guaranteed to knock your socks off!
Guns with rusty steel instead of normal steel, constantly malfunctions and is very hard to aim
Even more furry costumes ^w^
If you deal a killing blow on a manhack or other type of 'hack, there is a chance (decreasing with the amount of overkill damage) that it will transform into a damaged one.
Types of damaged 'hacks:
This a bit off topic, but do would furries mutate just to be furries?
Asking for a friend
you mutate just because you find some free rads laying on the ground? right?
but to be serious i went with a somewhat feline character a few times in game, i dunno though, it doesn’t exactly seem as beneficial as the other options so i usually go either slime, medical or whatever else is easily found and available.
Feline mutants must attempt to sit in any cardboard box they come across and, on success, accrue a morale bonus proportional to the time spent in the box.
Found a Radio Car Box? Home Frontier Starter Pack? Too bad; you have to sit in the box for half an hour before you can use its contents.
Give the vehicle code NPC AI, then your tankbots can be multi-tile beast.
Increase in acetylene torch ，Causing banks to be more vulnerable，Too much power armor in the safe
smoke Zombies in the latest edition， It seems to have disappeared.
Make power armor invincible
This makes the game boring.
Your attack/defense bonus and morale are affected by the type of music playing(pos or neg effects). Finding new music is required to keep up the full music boost. Each char has different music tastes, each music genre has different buffs/debuffs and collecting usb/sd/mp3 players give you a wider selection of music. Special cord allows transfer of music between devices. So a char that likes rock, listening to a unheard rock song that has a bonus towards def will gain an extra morale and def boost. A rock lover listening to a pop song for the 50th time will suffer one-three debuffs.
That’s like something I asked about the other week.
Apparently there’s a mod that adds cassettes, dunno if that morale in this way though.
MREs should have a random chance to be faulty/contaminated, causing a potential of getting Food poisoning, actual poisoning or maybe some other random thing when eaten…
DAAAAAnd good idea 
Vomelet chance should always be 100%.
disclaimer: might not actually be terrible:
cbm that gives you dr who like ability to step out of time if you ever find yourself in an “oh fudge” moment and need to try again, robs you of all bionic power, cripples bionic use for the next 4 hours and has a chance to attract “attention” to you.
basically you can step into the tardis, rewind time and try again.
-Kevlar Chaps; similar to Leather Chaps, except the kevlar would have 5 encumbrance instead of 3. Due to the kevlar being a little stiffer than leather.
-Kevlar Arm Guards; self explanatory
-Sawed off Stock; as an option using toolbox/hacksaw. Lowering the volume/weight on the weapon. Perfect for shotguns when you want a quick draw with weight. Wip it out and you don’t need much close quarter accuracy. Just the fast mule kick.
-Change gun shops back to being closed range(already corrected?). New england does have any open range shops, anywhere near a city. Only rural redneck areas. They would be illegal because of the bullets could kill people down range.
I actually like the idea of having all my must have items still on my person when I drop my pack. Like sheathed weapons.
Grappling be in game similar to Axu, except the success of the certain thing you are doing is based off of unarmed.
Spoilers for Axu meta:
Can’t really put a blur for spoilers, so just skip over the next part.
(If you’ve never played, martial arts is the most overpowered skill to have because you can spam the strangle to incapacitate your foe, then spam the pull head button to instantly kill them).
