I really like liked the point defense mod for homeworld and I want to get one for sins. My current idea is to create a new class of fighter, called "Missile", and have ships that fire missiles fire the "Missile" fighter instead. There is already a built-in utility for whether or not a weapon can hit a fighter, so all I have to do is set that to true. To compensate for the ability of a ship to destroy missiles short of target, I would greatly increase the range of missiles. For the point defense turrets, I was thinking of taking the turrets from the anti-fighter frigates and putting a few on capital ships and maybe one or two cruisers. I would be afraid of putting point defense turrets on more ships because that could make missiles obsolete. I would give the "Missile" very low hull and give the point defense turret very low damage so as not to make normal fighters and bombers obsolete.
For each ship that had missiles, I would add "x" amount of command points for the number of missiles that they could have at once. "x" could be increased by a new type of research, "Fire Control", and for each level, "x" could be increased a certain percentage. Unfortunately, this would interfere with ships that had both fighters and missiles. To compensate, I would remove all fighters from ships with missiles and replace missiles with another weapon on carriers.
Another idea I had was to make lasers very short-ranged but have them penetrate shields and do 100% damage to hull. Plasma and wave weapons would remain unaffected (shields, then hull).
This mod would most likely have to be for entrenchment.
What are your thoughts?
