Late game still has all the stuff from FMP, which is pretty substantial to be honest : advanced MIB troops, alt alien types, new tech and weapons...
FMP was a wild ride by itself, never beat it (slightly late in research because I got complacent, and lost because I didn't go for the final solution) but got incredibly close. So late game content wise, there is indeed a few extra crafts n weapons.
I personally like how its a long journey in this mod, and I dont mind that this slowly ventures through all its phases : though
By the way, the accuracy of an aimed shot on the blackops assault rifle is pretty woeful : the AK74 is better in this aspect, and honestly I think having it at a 90 or even 95 would make sense : the standard rifle often functions as a sniper rifle, and while I doubt a bullpup short design would be as close, I feel it would be a lot better than that.
