List the ones that you think would be the most useful here in this fight.
well most of Frank arsenal is going to be incredibly useful, especially his combo weapons which can easily throw Chris off with how random they can be
The Air Horn can easily disorient Chris with how loud it is and even likely kill since it can easily cause Zombie head to explode but its range is limited, same for the Power Guitar but with added AOE shockwave which can blow Chris back
any of his Acid based weapons can burn Chris skin with ease, those being the Acid Maul, which causes a massive splash of acid when used and Jurassic Barf, which allows Frank to spit Acid balls out of the mouth
Electricity based weapons can be used to stop for a lil bit, those being the Electric Chair, Electric Crusher, Electric Rake, Electric Axe, Electric Wreath, Roaring Thunder,
has many bladed energy weapons that could cause serious damage, those being the Laser Sword and Laser Slicer
his flame based weapons can leave chris burned up, those being the Burning Skull, Flaming Gloves, Infernal Arms, Flaming Sword, Flaming Helmet
he also comes packed with a ton of other weapons that are simply just blades for more cutting power, those being the Equalizer, Roto Killer, Glass Knuckles, Knife Gloves, Paddlesaw, Porta Mower
any of Frank drinkable items are going to be incredibly useful, mainly the Energizer which makes Frank invincible to all damage up to 30 seconds and Quickstep which allows Frank to move much faster then he usually does
and note that all of these weapons are much stronger then Frank, being able to one-shot zombie who can harm Frank and tank his punches with ease. this is just what I found for those categories, Frank has a lot more but some are very similar to other ones
