First, I'm not posting anything I want done. This is simply a place to take out our frustrations on simple thoughts we think would be rather nice if added to the game. We're not looking for flames, rants, or revamps, just random thoughts. C'mon!!
Flamethrower-
Napalm strike-
Fires a condensed 'charge' of the burning liquid-fuel at a target- extreme fire damage, auto-DOT, possibly a slowdown in attack or something. (You're wearing burning clothes and your flesh is melting. Think about it. >.> .. <.<

Fire rain-
Raising the flamethrower in the air, and setting dispersale to extreme-range, the commando spreads his attack, albeit it weak due to the indirect nature, to all enemies surrounding him.
Incendiary (sp?)-
Setting the dispersal pressure of his nozzle to maximum- the jellied-liquid substance fuel within is directed at the target in a cloud of highly-'stickable' 'flachetes'. Though not causing much more than an extreme stinging (Keyword: Low damage) this attack severely hampers electronics and the action pool. (Who the hell would want to run through a wall of fire? Ow!)
Fire Blanket- (A real, freaking, fireblanket)
Recall World War II? Panzers or Shermans with flamethrowers attached, completely annilhating random, flammable enemy structures? A Flamethrower-unit marching into a building and making it hell? Exactly.
Setting the 'spark-plug' (Heh..) to an extremely high temperature, and widening the fuel-ejection nozzle, the commando can completely waste whatever lies in front of him in a blanket of fire. Large cooldown. Leaves the commando immobile while performing. Covers 180* infront of the player.
Acid Rifle-
High concentration-
Targets two nearest enemies for an extended period, no change at all to any statistics save the cooldown times. Changes to 1.0, for six seconds. Medium cooldown as fit.
pH Burst-
Commando sends a large fan-type spray of acid into the air, causing corrosive (DoT) damage to all enemies within a certain amount of meters. 360* (This is meant more for group-fighting, than solo.) Short cooldown.
(On a sidenote, a natural boost in damage to any metallics would be good. Biological lifeforms take decreased damage.)
(Think about it, acid seeps into metal. Flesh is not exactly known to take most acid in well.)
How about a backpack for commandos, for the flamethrower, which was supposedly filled with fuel and cutdown the time between attacks? Lasted for a certain amount before refueling was required. Specials made no difference to it.
(Length of time is judged by active 'Combat' time.)
Shields-
A large, gladiatorian-style shield to be held in one hand. Think Halo, with the Convenent.
Extreme defenses, improved chance to block. Accuracy for selected weapon plummeteda good deal of points though.
(Made for entering in behind enemy lines, or retreating. Generally you don't try fighting with a huge f-ing shield. ^_^)
