I got every achievement from all halos pre halo 5. a lot of the ones on this list are pretty hard. endure and two for one id say would be the hardest ones imo. but, in the wise words of some marine, “the only thing worse than jackals… are jackals with sniper rifles.” ooh, and mongoose mow-down for scout shoulders in h3 i remember was a beach to get lol cuz most of the time it would just slightly tap their shields if u didnt get it just right
story of battle droids free from mind control who dont want to die. interesting.
