We do need something like that. Such a shield could motivate a ground attack. Once the shield were disabled, ships could fire on the planet to support ground troops, or ground troops could be evacuated and the planet blown apart. Before someone starts screaming about balance, remember that planets are really not very useful right now, and that such a shield is
necessarily going to be severely (even brokenly) overpowered compared to ship weapons and shields in order to encourage ground warfare.
I haven't come up with any good numbers yet (too early in the morning!), but here's an idea of the shield's effect.
- Mechanics: A dodecahedronal shield encompassing the entire planet and providing absurd defense.
- The shield is rather expensive per block, but uses grouping effects similar to power reactors.
- There may be one shield grouping per plate. Groups across all plates contribute to a single, planet-wide shield pool.
- The shield itself behaves similarly to planet HP. It regenerates rapidly even under fire, requiring a strong, sustained bombardment to break.
- Rather than stopping shots when they hit the surface, the shield stops weapons fire high in the atmosphere to protect ground vehicles and troops.
- It is possible for small craft to fly through the shield, although it has some harmful effects. The goal is to make it impossible for large ships to do anything of note inside the shield, while allowing fighter-bombers and dropships to pass through.
- On contact with the shield, weapons are disabled for a few seconds. Scifi excuse: Shield energy briefly overloads targeting systems. This applies to hostile and friendly alike.
- For enemy and (optionally) neutral: Shields are drained rapidly every tick a ship is in contact with the planetary shield (i.e. while passing through the shield or skimming its surface). It takes one second for a ship shield to fail completely regardless of size. A small craft can get through in a fraction of a second, but a larger one that tries to do the same may wreck into the planet or fail to get through in time.
- An unshielded ship in contact with the shield takes armor and structure HP damage every tick. The magnitude of the damage scales with the max capacity of the planetary shield. Block destruction could happen but isn't necessary IMO. Battles are CPU-heavy enough without an energy field rapidly eating thousands of blocks.
- For Pete's sake keep your Titan's nose OUT of the shield!!! It's overpowered for a reason.
- Balance: A planetary shield should be many times easier to build than a ship capable of overwhelming it.
- Scenario: Newbies land on a planet. Within a matter of hours, they've built a mining ship, flown off, mined asteroids, and build a shield virtually impermeable to a 5000 mass ship.
- Scenario: A mature faction lands on a planet to establish a forward base. In under an hour, they've installed a shield too strong for even a Titan to pierce.
- An enemy faction launches a combined ground and space assault in attempt to take a fortified planet, but the ground troops fail to disable the shield so the space assault is useless.
- An enemy faction assaults a planet with a ship comparable to the Death Star, nearly half the size of the planet under attack. The shield is gradually brought to its knees by the super-Titan's weapon system and finally fails after a 30 minute bombardment. Less than a minute later, the planet gets fragged. Hmm... might have been more fun to launch a ground assault.
A mechanic like this could eventually replace home base invulnerability, simply because a truly invulnerable base would no longer be needed.
This would also fix some complaints about small and large ships. Small ships could do something Titans will never be able to: fly in below a planetary shield to attack things.
Ground assault vehicles could be usable on the surface if only small ships could be used inside the shield.
Just a thought: should I copy this post into its own thread so it gets more attention?
