^That's pretty much where I am right now. I have 62 weapons fragments and I need 75 to research the new interceptor...and just to take the piss, Japan is asking for 18 in exchange for some cash. Fortunately, I just got an abduction mission before I saved, so with a bit of luck, that'll get me some more resources.
Still, my "get moar monies!" strategy appears to be paying off. With one council report I was able to buy three titan armours *and* plasma weapons for my main sniper & heavy. I think I'll hold off on the ghost armour for now as it looks like it chews though a *lot* of elerium and I think I'll be needing that for other things.
