Tanka - Heavy's secondary
It grants the heavy completely ignored damage falloff, how far the heavy shoots the gun from doesn't matter. But the damage is decreased by 35% by default. How fast you can turn your camera now has a limit, Your camera sensitivity stays normal but there is a max turning angle per second. If a scout is circling around the heavy equipped with this, It works like running above the sentry. To make the one equipped with it visually noticeable, change the tracer colors to meet the team color, but don't make them too bright as crits.

Tankha only limits the angle of turn per second when you are wielding a primary weapon. All the effects are exclusive to the minigun, the weapon in the secondary slot is never affected.

Prone - Sniper rifle
The taunt forces you to shift on a prone position, and the hitbox is according to the visual appearance. But the hitscan originates from the center of the character, meaning you can't clip inside the wall to poke out your head. Even then you can't fire through that situation, the enemies still might shoot the sniper's head though. Sniper can only move to forward, the camera can still turn the direction though. It works much like any other drivable taunts. The sniper can't fire the gun in the third person mode, but the perspective is forced back to the sighted screen whenever you m2. And in the scoped screen, you can fire the guns. The charging meter functionality is completely omitted. It's actually a damaging taunt modified to recreate the sniper rifle rather than keeping the original sniper rifle's system.

Sky Waxen - Flare (The name can be "Glare".)
Basically a detonator but only able to fire above with a maximum incidence(cone) of 35 degree. The flare can be detonated after 0.3 seconds. A damaging zone will be created around the place the projectile is detonated, it works as a barricade to counter flying classes. The damaging zone is visually oriented with a sun-like visual effect (hence the name glare).

Youkou ( or Signal ) - Flashbang Flare
When directly hit from far away, the enemy is stunned. Enemy is ignited for full afterburn.
The projectile itself deals 30 damage. No critical hit damage. When launched above, it will automatically detonate after a short period of time and stays in the air. Much like a battlefield illumination.

Vermin - Sniper's smg
killing an enemy will grant a full charge for the weapon. alt-fire activates the "active protection" mode. When you fire your weapon in that span, the enemy projectiles on your sightline is registered as being struck on a surface. Causing them to explode prematurely, As long as the projectile is far from your position it will be safe for the sniper. But if the projectile is already too close , the mid-air explosion will damage the sniper.

Ordinary Pipe launcher
- fuse is activated after the pill hitting the targets, 0.5 seconds delay.
As long as the projectile is in flight, the pipe never explodes.

Daylight Hoax
When spy attacks opponent with this knife, the positions of the 2 players are swapped. But the direction they are facing is kept. Spy has to flip 180 faster than the opponent to stab. Backstab reduces the enemy's max health by 50%. If the enemy is already attacked by this knife, the enemy is marked for "flipped" state, if the enemy is in the "flipped" state the backstab behaves normal and deals 6 times the max health.

Digaloath - Demoman's sticky launcher
M2 detonates the oldest sticky only, maximum number of stickies on the ground is 3. Putting 4th sticky automatically detonates the 3th sticky like the stock. But the damage is slightly better. Around 20% damage increase. The max clip size is 7.

Lacks - Demoman's primary
The pipes disintegrate mid air and creates a forward hitscan based on a shotgun. The pipe doesn't explode, the pellets are released after 0.4 or 0.5 seconds. If the projectile touches the ground or targets before the shrapnel kicks in, the projectile creates very small explosion upon impact. The impact damage in that case is comparable to the stock.

These weapons are separated from Scrampnel.

Pyro's melee
-15 max HP or -5 hp every time you airblast.
Reflected sentry's salvo deals 4 times the damage against the sentry.

Heavy's melee
Taking ammo boxes added to the meter, much like Medkits refilling the sandvich. When you get healed by the dispenser, the metal is added to the dispenser.
