Today and started to play all campaigns In difficulty, the most serene to reality, I really do not know what to say in these forums, But it’s fun
I’ll start with Halo Reach
Wish Me Luck And Have Fun By Playing 
I have only one mission left in Halo 5 on legendary, after that I have beated all of them again.
Playing campaing is really fun.
The halo reach missions are easy in legendary mode.
halo reach is pretty easy on legendary. I completed it solo. The trick is to be patient and always have a plasma pistol and a spike rifle
