bullits dont need oxygen to fire, they are in a self contained case anyway, they have all the oxygen they need inside the case
Freeza and I have come up with a new weapon that may be useful, it has been nicknamed the pipe organ, you will see why in a minute
to understand this weapon you will first have to understand what metalstorm is, here is a link to the wikipedia page
http://en.wikipedia.org/wiki/Metal_stormas you can see, with metal storm the barrel itself houses a rather large number of projectiles which are fired electronicly allowing for a fire rate much higher than even the most high tech chain gun
the only disadvantage to this system is the diffuculity of reloading, which I beleave I have remided the problem
here it is
http://www.freeza.outpostuniverse.net/ima.../Pipe-Organ.jpgfreeza went a little overboard, there are only supposed to be 16 barrels and the loading system (ill explain later) should have 8 loaders instead of 4
basicly this system has the metalstorm barrels mounted on a rotating belt, the outer belt you see is for stability, half of the barrels on the belt would be above the vec while the other half as with the entire loader assembly would be inside the vec
as a barrel emerges from the vec it will start fireing, once it has made its way around it should be exausted of all its projectiles as it makes its way back into the vec
once inside, a cylinder would rotate with the breach of the barrel, a new strip of rounds would fall into the hopper just behind the barrel where it would be pushed into the barrel by a ram while the whole thing is rotateing
so for an ingame version of this turret you would only need to have 8 exposed barrels and the tower that supports them, to fire the barrels would rotate around the tower and anyware from 20 to 50 rounds would come out of each barrel
needless to say such a weapon would be devistating, ill leave it to the op3 team to try and balance it if its accepted, if it can even be balanced lol
