Navy: your dead in the water now you pirate filth, be smart about this and surrender
Pirate: never you filthy pigs, *covers comm* Bilkins get the systems back up
Navy: you pirates are all the same...no brains
no but seriously, we should have them on capital ships, without cruise engines, like the dreadnaught or BS...that way in a fight, you charge the weapon, and either a) disable the enemy ships to enable you to retreat, or b) disable the retreating ships, and force them to concede
the Ion cannon could be implemeted on the Liberty cruiser, as it would replace its main cannon, but the down side to ships with this, would be that 1 shot, completely drains all power.
you could even make it so that it had a timd recharge, lets say like cruise engines, but slower...that way, you would have to choose when to use it and when not too...I.e. if you fired it, and knocked out 3 cap ships, and a fighter, but left 3 gunboats intact, you die, because you cannot fire again till system reset
