Update:
I'm in the middle of adding the grav techs, and I discovered that the sector - sensor interference ability dosen't work on components
I currently have:
engines for ships & fighters
(grav tech lev 1-4, and 2-5)
Graviton Flux Cannon (platform weapon)
(grav weapons lev 4-6)
Adv. PDR
(grav weapons lev 1-3)
In progress:
Missile Launcher upgrades (+4 speed all missiles)
(grav tech lev 1-5)
Still to add:
Singularity mines
(grav weapons lev 3-5)
Racial Techs (to be added):
Crystalline - missile upgrade
Organic - missile upgrade
Psychic - ?
Religious - ?
Temporal - ?
Note: I increased the power of those platform GravyGuns, and now, at optimum range, the level 1/2/3 cannon has a damage rating of 2.5/5.0/10.0, armor piercing

, but the damage
does fall off exponentially (half power for each square away from optimum).
