What do you think?

I'll be polite and just say: "It needs work"

Thanks for being polite. When I was making this post, I was wondering how it would be good for this game. I should keep ideas to myself in the future...Maybe make my own game using my ideas but that's years away.

i would say dont get discouraged. although this exact idea needs a bit of work, you never know what your idea will lead to. Other players might read this and spit out a spinoff idea, that your idea was directly related to. ive put out some pretty awful ideas. but i also know ive put out one good idea (legion governments) so just keep throwing em out there. you never know what will come of it.

This sounds alot like equipping runes to modules, or equipping runes to your ship, which is rather interesting. i dont believe anyone has suggested something like this before. Although your attack fragments seem a bit overpowered (the attack twice one i mean) your defensive ones seem to lack the ability to counter them.

What i would say is what if when you research modules for each mk level you would gain an 'Alien Technology Infusion' slot, where you can choose to infuse a fragment with the module. Each npc faction would give out a specific type of effect to the module, and that would have to balance out to make this a viable source of gameplay. Effects gained could be

*5% increase to modules effect, +10% upkeep
*-5% upkeep
*+5 repair levels (so it can take more damage)
*Tactical Cloaking-(does not show up when other players see your ship, if a weapon or defense, then cannot be removed with a tac bypass)

these effects would ONLY be able to be equipped on an improved module, for a maximum of 3 slots available for cannons, 2 for reactors, etc...
