although if it could be coded in with galaxy forge it could be an awesome discoverable artifact type thingy. DEATHBEAMOMEGA launches massive beam of doom at incoming spacecraft...

There was a guy who designed a supercannon which could launch shells, or other payload, into orbit.

easy target isn't as important actually.

As presented by the site Atomic Rocket, something that is immobile will have to have much more shielding (this is easily available on a planetary surface, MUCH more room for shield generators, armoring area, and ammunition storage), and much bigger guns.

True, I can only think of a few ways to avoid that. 

One would be to make the siege frigates have a longer range than the defenses, which would make the defenses useless against them so we would almost be back where we started.  There might be a way though if the range is tied to a deployment 'mode'.  The ability would give siege frigates a much longer range than a planet's defense system but would make them unable to move.  Then add a 30 second or more time delay when changing modes(can't fire for 30 seconds after deployed, takes 30 seconds before it can move again when ability is turned off).

The second way would be to give a planetary defense its own hitpoints that can be damaged by any ship.  This would let a fleet destroy the planetary defense and then bring in siege frigates when the threat is gone.  It would however be much harder to implement than the first way.

Cool that you will consider it. BTW, could the possibility of this scenario be considered for a future of the game:

The faction which has been annihilating the Vasari finally reaches Trader space, and all three other factions then have the necessity of joining forces in alliance to combat the mutual enemy?

"Unrealistic" I love that it must be the best statement Ive ever read on this forum...

So tell us which planet did you last see firing weopons into orbit against an invading fleet? cause I havent seen anything like that in my telescope  as of late

I'd love to find out how people can deem stuff like this realistic or unrealistic when no one has even gotten past the moon in real life lol

For Sins 2, the whole planetary system needs to be looked at.  I want to see planets become more interesting in general, not just in terms of defense, but in development, too.  A seperate tech tree of planetary development would be a good place to start.  It could include habitation, defense, even political techs to research.  And while they're at it, add some sort of ground war invasion option, too.  It's such a big list of possible changes that it needs another major overhaul, as with Diplomacy.  Hence, I doubt it will apprear until a full expansion or sequel is announced.

As for planetary defense missiles, Sword of the Stars has them.  Basically, a planet fires a handful of harrassing missiles evey so many seconds.  It doesn't really accomplish much except to possibly destroy an already weakened vessel.  If that is all that is to be added, it really wouldn't add much to the game except to chase off some very weak planetary assaults (really, an orbital defense platform accomplishes the same thing).

Thats a good point,,,though you have to consider targeting, there is no range limitation (save for any obsticals that may be in the way) but keep in mind that a ship as in sins would be a very small target in the vastness of space, at a certain distance range is likely to become a major problem since hitting small targets is never easy evenn with a big gun

After reading all the "it's unrealistic and not energy efficient", I have to say one thing.

Novalith. It shoots a gigabomb between solar systems to blow the living hell out of a planet.

Kostura. It causes a planet and gravity well wide EMP burst.

If these guys can do that, then surely they could do such a measly thing as punt a missile into orbit?

Cadalancea

I think a weapon based on each race history would be cool.

Tec big ground based beam weapon.

Advent how about a Pychic wave making some "crew" go beserk and trash the ship till it self destructs? 

Vasari ground based phase missiles.

They should be like beam defence damage wise and take up a decent amount of tactial space just like a space based weapons do. One big thing could be they do is attack a ship no matter what postion they are in orbit around the planet.

Maybe a limit of one or two max that you can build. With a Tech line to increase target count by one or two and a increase in damage.

considering how the TO went from nothing more then a policing action against Pirates to Stalling out a Race of Aliens with God knows how many millenia conquering less experienced races..........Im pretty sure TEC, Advent and Vasari are more then capable of creating a planetbased anti starship weapon.

Talk to -Ue_Carbon about that, he is trying to build a mod that does it

fine dont....

but can u at least allow planets to have active abilites that can target other objects (ships, structures, etc)?? modders like me can fill in the rest
