Yuri was able to start re-creating the old concept design tonight, this is what he has so far:
Obviously it's not even close to finished yet, but I'll give the master time to work =P
As far as the forward gun goes, I thought it might be an interesting change of pace to have a delayed firing mechanism used for it. In short, you'd click the fire button, for 1-2 seconds you'd hear a 'charge up sound' and light/energy would build within the mouth of the ship, then it would fire off. Alternatively, it could do the charge up effect and then have a high rate of fire on the weapon itself (anywhere from 6.00-10.00 perhaps), not quite enough to be a 'beam' weapon but something that had the feal of drilling through an enemy vessel.
Of course, delayed firing makes aiming much more difficult, so if you didnt go with the high refire style of weapon you'd probably have to have higher damage potential or make the weapon track slightly, like cruiser/bs missiles do.
