I like the idea of a small stealth ship transporting a small squad of troops into a large capital ship to destroy it from the inside, fight it out with the crew and troops on board, or even quietly sabotaging the ship\'s inner workings. So I would suggest customizable explosive charges. Something that a player would carry around and then plant on an enemy ship that they infiltrated. They could use the same weapon building system you mentioned earlier, with many different parts. I was thinking something like an explosive core, similar to the weapon core, though larger, with a few variations that provide different activation sources: timer, remote detonation, and explosion upon damage. The parts added could be different explosive types that customize the radius, damage, and damage type of the explosion. So there would be a block that adds damage to hulls, a block that adds damage to shields, a block that adds explosion radius, and a block that temporarily disables systems in the radius. Imagine a large battle, in which a near-invincible capital ship suddenly finds its shields disabled, or perhaps its main cannon, or even its generators. These explosives could be mixed and matched, though there would need to be a size limit to force players to customize their explosives, and to give them a reason to carry multiple explosives. As another idea, I would like to suggest a device that can be attached to a generator that disables it and interrupts the patterns that generators rely on to produce a reasonable amount of energy. Attatch it to a corner of a large section, and the power generation would be severely crippled. This would make protecting your generator more important, and would encourage smaller backup power generators, and even some automated defences like small turrets in a hallway.
