I've actually developed a "Smokey SA-8" for testing purposes. Nothing conclusive, though if you do get hit, you just get the effect, much like the AA-11 I did. Only thing is if it hits you, I'm guessing game logic is a culprit since once it shoots at me, either hits or misses, it doesn't fire anymore. Not sure if the SF2E SA-8 is a one shot wonder or what... but it wasn't like I was dodging it either. Anyways, here's a screenie of me being hit by one:
EDIT: I figured out the problem, it shoots at you pretty well, had to adapt it for the SA-8B and it fires as it should. Forgot about the upgrade issue. Anyways, it uses the same missile so if you get tagged, it just explodes, no damage.
