We need crazier weapons, ones with severe drawbacks. Like… a fist like weapon with jackhammer parts strapped on it. Can bash through walls when activated, but gives a lot of encumbrance to the hands, and some dexterity loss, since it is more or less a jackhammer strapped on your hand. Or… a fist with an acetylene torch strapped on it. Can cut through enemies and doors with it’s torchy bits… and might cut you by accident. Or explode.
If fact, make a lot of things be able to be strapped on your arm. It’s the end of the world, and you should take the chance to go out as crazily as possible!
C4 gauntlets. Good news is it hits that zombie hulk hard enough to send IT flying for once. Bad news is it does the same thing to what used to be your assorted body parts.
how about gauntlet gauntlets?
So you can brofist a zed and then hed be atached to your gauntlet gauntlet.
Complete with trigers to detach the extra gauntlets. Fist them zs till there are no gauntletless zs left.
A sticky/very sticky/extremely sticky mutation. You get some extra volume since you can simply stick things on your body. On the flipside, you get some encumbrance since having stuff sticking out all over can get in the way… and a more or less inability to properly throw things without gloves, also due to being sticky.
Tentacles, huh… how about regenerating tentacles? If it arms get broken, it’ll slowly fix itself over time. And if possible, provide a snack if you’re really, really, really desperate.
