Would be cool if you could actually improvise new weapons using junk you pick up, instead of just picking up a blueprint. Also, some of those weapons held together with duct tape, like a circular saw duct-taped to a stick ?

As you can see, my man is in the middle, either morbidly obese or wearing a sombrero. Attached to his utility belt are 7 heavy duty sticks. At the end of said sticks are circular saw blades, each powered by a posh motor. No zombie's getting through that.
Of course, there are downsides. Every doorway is hazardous, and you risk bringing the building down on you. Also, you'd be vulnerable from attacks from above, posing serious risk to your sombrero, if you happen to be wearing one.
Attacks from above could be repelled with a very strong point to the sombrero, which would also have a steel cage support to channel the force away from the wearer's head to the ground.
I'll do a daily check and let you know if I see it. Although that isn't exactly exhaustive since it might change back again. We might need ant to make some sort of monitor with a raspberry pi.
