I imagined this could be a weapon to hunt down specific classes by the name of Hunter Shotgun

Sides
-M3 to change Ammo type (must empty all shots in an animation and then reload again)
1. anti spy rounds
Pros
-mini crits on disguised/cloaked targets
cons
-50% damage penalty
-no random crits

2. Anti scout
Pros
-slows scout for 3 seconds
cons
-can only damage scout

3. normal (normal shells)


Overall Downsides
-only 3 bullets per clip
-slower fire speed

"Lets shoot those Soldiers out of the sky!"

+10% Damage
+25% Faster fire rate
+50% Tighter spread
Mini crit on air-borne enemy players
Explodes rockets/pipes/stickies when hit mid-flight

-50% clip size
-50% ammo
-10% reload speed
No random crits
No ammo from ammo kits or dispensers while active

The Panic Attack would prove to be useless by this.

implying PA isnt already useless compared to normal shotgun

Are you serious? Bullet spread and headshots? How could that work????

Maybe -16.67% clip size (5 max in clip, 5 shells on the side?) and 15% (?) extra damage? Stats should probably be kept simple for sanity's sake

+crit at very close range (like 3 steps away close)
-1 max clip size
-25% slower fire rate
-no random critical hits

Some kind of long range hitscan weapon, maybe it shoots some kind of slug. The heavy is purely a close-medium range class and this would help with his versatility a lot. It should fire one bullet. Here are my stats:

-2 max clip size
-minus all the pellets except for one
Hidden stat: That one shot does about 60-70 damage which is like a normal shotgun shot.
25% slower fire rate
10% slower reload speed
+knocks back enemy (More knockback at closer range)
Damage in close to medium range does not change but hitting enemies at longer range (15 and over meters) will do increased damage, the farther away they are.
On hit, puts tracker on enemy. Only one tracker can be active at one time. Trackers can be airblasted off or washed off. Lasts 20 seconds naturally. When the tracker is active, your whole team can see the enemy tagged through walls. You do minicrits to the person tagged, but he has 30% damage resistance against your teammates. The enemy has a team colored outline around them (Their team color) This is kind of a tag and kill weapon, where pick off weak/high value targets.

How do I install the skin?

Call it "The Big Game Slugger"

-50% spread
25% faster reload
Minicrits on overhealed enemies (?)

-50% ammo capacity
Only 5 shells per clip
-15% firing speed

I think this should be something that could be used to take down bigger, beefier classes.

PROS:
+25% damage bonus
Crits on airborne targets
+20% max primary/secondary ammo on wearer

CONS:
-15% slower firing speed
No random critical hits
You are marked for death while active, and a short period after switching weapons

Marked for death is not such a good con to balance it.
