This might sound dumb, but perhaps there is a way to fairly implement a cloaking like device, imagine a counter measure with a extremely long refire that went shot makes you invisible on radar for a short while, not invisible to the eye, just to radar like a stealth bomber. Of course ammo would be extremely expensive, to avoid over use of it, and a long refire.
I would like to know HOW they got it to work correctly.
I see no reason why it shouldnt be implemented... though it would need to be put in carefuly and with many restrictions such as it being limited to certain ships.
