Reach was far easier because you always had the helpers who don't die, I did it on reach with no troubles at all except at the end when you're in the huge turret and have to shoot banshee's and phantoms and stuff down in a certain order or you die during cool downs. That took me so many tries,
This one isn't too bad, i'm only on the second mission but it's because i'm going for the other stuff first. Just got 25 challenges done, and the level specific challenges. I have 42 achievements, and it's soon about time to start solo
shouldn't be too bad, i get bored quick though... at the time i had reach i didnt have many other games to play, now i literally have 100+ EASY.
