It doesn't have to be subspace technology, that was just another idea someone threw out there. It's an interesting idea, and could have a lot of potential, though.
Also, as for flak, can it be launched from a fighter? If it can, some sort of acid flak might be an interesting effect. Even non-fighter launched acid flak would be cool. What sort of shield, hull, and subsystem damage do you think such a weapon would cause?
For the subspace inhibitor, I was actually thinking sort of both... it would both prevent warpouts and warp-ins. However, I think preventing or relocating warp-ins would be harder to FRED than preventing ships from jumping out.
The Lamia is kind of cool looking, but I don't particularly like the three-way symmetry. Even for Shivan it looks kind of funky weird. Heh. Even... Shivan... rhyme... and it was accidental too!
Subspace specific ships and weapons don't do it for me... they don't seem to belong. I'm going to start a new thread about subspace, how it works (not the physics but the gameplay), some inconsistencies I noticed, and stuff like that. This thread is still open though. You don't have to limit your tech ideas to ones that will benefit my campaign either, because, although special help would be appreciated, I have barely even got a framework ready. Actually, I don't even have that.
