Pros:
if backstab spy will be marked for death
Cons:
-50% ammo

-50% ammo
-25% damage penalty

On hit: Enemy bleeds for 5 seconds. (this effect does NOT stack, for example if a scout is hit with one bullet, he now has the debuff for 5 seconds. If he has 3 seconds left of the debuff and is hit again, the debuff timer resets to 5.)

Shoots Flaming Bullets That Ignite Target
More accurate
On kIll/damage (?), charge up rage meter, on full meter, create a large, heavily damaging explosion that sets opponents in the radius on fire, knocking them back, and deactivating sentries for a few seconds. Heals you for some of your health, depending on how much damage you do with the explosion.
Killing an enemy with the explosion gives you some charge for the next explosion.
-Less Damage
-Less Primary Ammo On Wearer
-Slower Firing Speed (Not Much)

Reskin for the brass beast.
Reasoning: It looks heavy, since it's ancient it probably takes some time to spin up and for some reason everything found in old temples is stronger then the present alternative.

Pros- +25% damage and 5 sec. of bleed,25% fire speed
cons- -10% ready speed

- Instead of hitscan bullets, the gun fires projectile darts that cause bleed on hit
- The darts themselves do little to no damage

I do like the idea of darts, so

-35% dmg
Instead of bullets, it fires small darts, which poisons the hit target for 5 seconds (3 dmg per second)
-50% ammo

(?) Shoots 4 bullets at a time
(+) 10% damage
(+) 50% accurate
(-) 100% firing speed

The Bleed on hit Idea could get really op. You could just shoot everywhere and that would be it. I do like the idea of spy marked for death, but maybe we could go in another direction?

Pros:

+20% damage resistance when spun up below 50% hp
+15% damage against buildings
Spinning up will cause the heavy to smash his minigun into the ground and do a small AoE attack, dealing 25 damage and pushing enemies, however, it will root the heavy in place for 1 second.

Cons:

-33% primary ammo capacity
-20% less accurate
Mayans' Curse: Switching from this weapon marks you for death for 5 seconds

When weapon is active:
Damage increases as health decreases up to +30%
+20% damage resistance while spun up
-15% slower movement speed
-15% damage penalty

*Damage maxes out at 100 health*
*Resistance is not the crappy one they did with the BB and Natascha, it's constant*

weapon shoot arrows
-30% damage reduction
-25% barrel spin
*can headshot {because of the arrows}

Shoots rockets at 1/4 of the normal fire rate, with 25% of normal rocket damage. Also allows normal movement (including jumping) whilst spun up

Since it's a huge artifact stone thing...
