"GHOST"
Visible only to owner while moving between owners base.Loosing invisibility when attack enemy base.
Speed factor is 50% slower than ordinary sub.
Promote to:
"EVADER"
Evade all ships on the line of his attack and continue to the target.
Speed factor is 50% slower than ordinary sub.
The idea is that it will allow concealed preparation for attacks.Ghost would conceal drillers & specialists onboard at the expence of speed.Evader would then try to successfully execute the planed attack.Immune against all specs unless intercepted by pirate or nuked out on base and overdriled.Again all at the expenxe of speed.
We could then fantasize about this idea further and make the intelligence officer upgradable to.
"INTELIGENCE OFFICER 2"
Increase empire sonar range by 35% & see ghost ( currently 25%)
