I came up with a few zombie-themed melee weapons. It's probably overkill, but I had fun thinking them up. I figured I'd share them with the rest of the community in case anyone wants to use them.
The list includes: pitchforks, plank + nails, sledgehammers, scythes, sickles, bowie knives, crowbars, brass knuckles, baseball bats, nightsticks, golf clubs, samurai swords, wrenches, nailguns, tasers, defibrillators, bullwhips, blowtorches, arc welders, meat cleavers, ice picks, waffle irons, tire irons, broom handles, pool cues, frying pans, rakes, and chainlocks.

Also, most of these items wouldn't be manufacturable anymore after the zombies attacked, so I was thinking about making a new race called scavengers or something like that, who trade these items with the survivors. I'll probably start working on that once I get the courage to mess around with entities.
