(+) On Alt-Fire: Uses "THROTTLE" meter. You are constantly moving forward (Like shield charge), impacting an enemy results in him getting damaged (Chargin Targe damage x1.5) and igniting.
(-) Meter does not recharge, meter fills by dealing afterburn damage. 75 afterburn damage is needed to fill up the meter.

(+) On landing: Stuns (Can't use their weapon but can move slowly) enemy players on a 2 meter radius for 3 seconds.
(-) 50% resistance to fall damage penalty.

I have an idea for Survival Gear.
(=) Rather than getting damage with the whole amount, you are getting damaged by 10 hp per second. For example: you were damaged by 60 hp. With Survival Gear, the damage splits up to losing 10hp/sec for 6 seconds, If you are damaged by 74, you are losing 10hp/sec for 7 seconds and on the 8th second you lose 4hp.

(=) Primary fire blows air instead of fire, works as a constant airblast. Alt-fire wastes 10 ammo per second and sucks all nearby projectiles in, and using Special Attack, you can release the projectile (stickies will blow by themselves after 5 seconds). Max held projectiles is 2. Other sucked in projectiles convert into 5 points of ammo.
(-) 30% slower draw/hoslter speed.
(-) 25% ammo capacity penalty.
(-) Air doesn't damage enemies, but blows them up, causing fall damage. Also considering that it triggers Reserve Shooter's minicrits, as it works the same as airblast.
Balance this lol.

(+) On active: The sentry automatically takes metal from you to replenish it's health and ammo. If it's not fully upgaded it will also take metal to upgrade. If you're out of metal, it will start taking ammo.
