Charge the "speed monster" by shooting enemy targets.

by pressing the "speed monster" bind
+25% speed
+25% fire rate
+25% speed when shooting

duration of the "speed monster" 20 seconds

When you activate the "speed monster" you are marked for death.

-50% income via ammo boxes
-Once the "speed monster" is active, your weapon makes more noise

Stats idea:
+) On hit: damage fills an "overclock" meter
+) Upon alt-fire: heavy gains a speed boost and 20% faster firing speed on all weapons, 25% faster deploy and holster speed
+) 15% damage resistance while firing

-) heavy cannot use alt fire to rev up his minigun
-) 25% longer holster speed

I'm not an expert balancer at all take this with a grain of salt.

overheat is too complicated so instead when spun up medic heals you idk 40 or 30 percent less? or %50 less ammo from all resources? really cool weapon

would be a interesting idea i will say.
