Traction skates - UPS powered rollerblades that drain the device per move but aren’t slowed down by unfavorable terrain.
Zapier - A taser tipped fencing foil for the post-modern corsair in all of us.
Tread mail - Because tire armor is awesome as has been suggested umpteen times.
The ability to inject your cat or canine companions with the appropriate category of mutagen to beef them up, at the risk they may have something of a falling out with you.
The bullwhip is great but could use a bit of a nudge. Maybe make it send non-zombie animals fleeing when you crack it?
Shields - I think I know how they could work now. ((I got the idea from the belted layer and wearable flashlights)) You wear a shield, like a holster or what-have you. It encumbers the arms and can’t be fitted, with larger shields encumbering the arms more. Shields provide a preset number of shield blocks per turn and depending on how large the shield is less damage travels through to your character. ((This idea came to me while I was admiring the new blocking mechanics, where plenty of damage from a hulk still ‘splashed’ through to my leg and splintered my quarterstaff)) Shields would need to be repaired on the regular and the biggest of them can be used to block projectiles.
Mutants with the huge trait should have trouble using low volume items and naturally use high volume items with greater ease than puny humans. Pulp the undead with manhole covers.
Survivor-style scattergun turret. Loads scrap metal as ammunition, fires like a shotgun, jams when trying to fire about a fifth of the time.
You shouldn’t be able to ID mutagens and serums without taking a hit or brewing them yourself. I doubt the scientists labeled them in a manner the uninitiated would be able to decipher.
New vehicle part type. Passive defensive measures. These would be parts you install that function like traps, some of them only so long as they’re powered, hurting any creatures that occupy their tile. Examples:
*Spiked plating (Yes, that spiked plating) should also hurt animals or unarmed attackers that attack any part of the vehicle with spiked plating.
*Heated door handles. ((When NPCs get to the point that they’ll try to steal your ride/stuff))
*Barbed wire or broken glass+superglue to slow/maim those passing over a tile.
etc etc.
