Only have made so much progress. I've yet to get the pitchfork or the pineapple to unlock either.

Pistol:Your starting weapon, get better ones.
9 damage
(Complimentary gun)

Vintage Gun:Like this one, better damage.
11 damage
(Cat army starter)

Alien Pistol:Burst fire, uses normal bullets for some reason....tends to overheat
10 damage
(Coming soon to a store near you)

Submachine Cat: Full auto, no overheat.
9 damage
(Cat army favorite. Uncommon find)

Revolver:A good mainstay, uses heavy ammo.
20 damage
(Raider-Girl fav)

Flare gun:Lights targets. If stuck to target, they burn until death!
5 damage
(IT BURNS! IT BURNS! ARGH!!!)

Toy gun:Arcade prize! Also, explodes after a few shots. Uses energy.
20 damage
(They aren't kidding, it will explode after enough shots)

Single Barreled Shotgun:Early shotgun. Find better when you can.
45 damage
(Enjoyed by weak catgirls and zombies)

Double Barreled Shotgun:Terrible spread, better damage. See if you can get a laser pointer!
160 damage
(This spread increases dramatic tension)

WEP_DOUBLE_BARRELED_LONG:Now with tighter spread! Become The One That Binds today!!!
160 damage
(Give it a laser sight and you are death itself.)

Shotgun: Good pump-action! If you don't want to reload after each shot, go for it.
76 damage
(Catgirl army veterans favorite! Comes with tactical toiletries kit!)

Short Barrel Shotgun:More spread, more damage, more round racking.
85 damage
(How does a laser sight reduce spread? Who cares?)

Auto Shotgun:Less damage, but more shells go out. Makes enemies cry.
65 damage
(Clears the room and then some!)

F.Maureen:Energy rifle, does good damage.
18 damage
(Does alt fire open tracking software?)

P.blaster:Not as good as Maureen. But pretty common.
16 damage
(Catgirls will start pulling these out. Be warned)

Rusty Rifle:Likely your first heavy gun. Has poor accuracy.
18 damge
(Find a Revolver ASAP. Least it's semi-auto)

N 16:Uses small rounds, does good damage, full auto.
15 damage
(Raider girls love it!)

Rail gun:Punches through targets, slow to fire. Energy weapon.
50 damage
(Use at long range.)

Pipe Rifle:Bolt action, hurts more than the Revolver but slower.
32 damage
(Aim for the head)

Flamethrower:Uses energy, lights targets.
7 damage
(Burns only last so long.)

Light Machine Gun: Heavy ammo hose! Saws through crowds!
18 damage
(Ace card does not increase luck)

Minigun:Small ammo hose! Has a bit of a windup.
12 damage
(DAKA DAKA DAKA!)

Rocket Launcher:Launches a rocket that explodes. Splash damage may apply.
30 damage
(clears walls and rooms)

Micro Rocket Launcher:Looted from enemy mechs. Fires faster than the normal Rocket Launcher.
20 damage
(Yes, the anime catgirls have mechs. You may panic now.)

???:Want a BFG that can't charge? Me neither....
1 damage
(Is this a joke, or does it need upgrade crystals?)

Dynamite:Good for walls and pipes.
(And ya know, enemies)

Every tool at once: Scythes and Axes can be founds on zombie girls. Sledgehammers can be found in secret rooms. Sledgehammers can break walls and pipes! Explosive damage may still apply!

Still in progress. If you know something I don't let me know.
