There isn't much to say on this, so I'll try to describe this as best I can. When dual-wielding guns, You could switch one gun to fire in the opposite direction. This would allow for some very efficient crowd-control.
I think there should be several options for dual wielding guns and firing different directions... Here are some of my ideas: Mirror which ever direction you fire you fire on the other side, it's mirrored If you fire like this \ it would fire like this on the other side / so you is _ this is what we get \_/ "Sticky" aiming when you aim a gun you can switch which gun you aim, but the other one can still shoot and points where you left it ie \_- You can control one and fire the other straight or something Opposite where you fire you also fire on the exact opposite side so if you fire left you would fire right too , down left, up right too. Well I guess that's it, I can't think of any other possible way...
I like the idea, but reloading should be a total bitch. In most movies where people dual wield, they just fucking magically have the clip float up and go in to the gun. the fuck? That doesn't happen. So yeah, I like the idea but it needs balancing like that. *dual pistols and a wink*
Hmmm if you get used to it it wouldn't be very difficult... it would probably take about 1.5x as long as just one gun to reload.
However, reloading two shotguns for instance, you would have to put one away since they are big and have shells, not clips. Although... what about dual plasma repeaters...? Just wait for them to cool down, then keep firing. Energy weapons will be so op! Hmm for christmas I want an electric arc gun!
