Defensive unit idea -> Spider Turret
Fires sniper-type shots that damage the engines of ships but not the health. These would make chasing down enemy ships in your systems easier - catching some of the faster ones can sometimes be irritating. The AI could also use these to help defend against deep raiding.
Love it, added to the future DLC list.
Just musing, since Vorticular Cutlasses and Vampire Claws became immune to tractor beams and were given infinite engine health, there no longer seems to be any particularly effective defensive strategy against them. A couple of points;
Is there a reason they have infinite engine health, rather than just a particularly high engine health?
I recall reading a few posts on this elsewhere, but I'll put forward my own idea regarding tractor beams and physical attack ships. The issue is that a vorticular cutlass trapped in a tractor beam cannot attack. Here's the idea;
Once a vorticular cutlass has entered the range of a tractor beam, it cannot leave the range of the tractor beam turret, but can move at a reduced rate within this area. This would allow cutlasses to be trapped at wormholes by tractor beam turrets but they would still be able to fight back and destroy the turrets holding them, along with anything else that happens to be inside the tractor beam turret's range.
This could actually apply to all ships - they could just move slowly within the range of the tractor beam turret's effect.
Actually, darke had brought this up in another thread, too. His suggestion was to make the Mark II Tractor beams have a slowing effect on all ships that are immune to tractor beams -- I like the fact that this is an unlockable tech, rather than something that is just a defacto always-on effect. The raider-type ships (and that now includes cutlasses and vampires) are supposed to be good at slipping past defenses, so it makes sense to me that you'd have to invest in better defenses to stop them (or have a lot of firepower waiting to snuff them out immediately.
My reason for having the cutlasses and vampires have infinite health is that they are 100% useless if their engines are out, so that was making them way too weak when engine-damaging ships were present.
It might be interesting to have a "Gravity Turret" that can be unlocked, and which emits a slowing effect on everything in its range (friendly and enemy). That might be one of the more expensive ones to unlock, but could be very useful for wormhole defense. Perhaps that would come after Tractor Beam Turrets Mark II.
