Sure, given the right set of missions. The three you got were not too much of a problem; I can do that with my inferior weapons. But I'm also stuck with crafted purple 70/32 armor, not 70/70 like you had. I've got to heal after walking over a mine and taking 70% damage. And on a HERC second wave mission, my 3 guys with RPK's are putting out so little damage (total 1500 dps), they get torn up, disengage, heal, re-engage, disengage, heal, etc, which leads me into running out of time and dying.
I've got a 26% completion rate on the HERC 2nd wave Monument (none at 100 pts) and a 65% completion rate on the HERC 2nd wave Compound (none at 100 pts). Even if you discount my earlier attempts as training and count just my last 5 attempts, I'm 40% for the H2 Monument and 80% for the H2 Compound, best score 50 pts, which I only got once on the H2 Monument and once on the H2 Compound. I have no time to take out the secondary objectives.
here u go
no uni armors this time, and a harder set of maps than last time.
Gonna do it again a few more times, try to get those "hard" second wave maps.
