How long does Halo 2 Legendary Take?

[A Son of a Shepard]

ODST took me a day
CE took me like almost a week
Halo 3 took me about a few hours as did Reach.

I never did Halo 2 or Halo 4,5.

I still have yet to complete Halo 2 on Legendary only on Sacred Icon and so far I am at a total of 7 hours. So I would say pretty long.

You can use some speedrunning tactics to get through Halo 2 legendary faster and easier.

I used the rooftop skip for Outskirts on Xbox One back in the day.

It's the hardest legendary. Especially that first level.

I have beaten halo 2 on legendary and if you can grind through the first level you can beat the game ...it doesn't get much easier but the first level is a good idea on what to expect from here on out. It was brutal but is my highest gaming achievement. Good luck Spartan.

you are crazy man. crazy. i just spent a few hours last night around at my brothers place with three of us taking turns in splitscreen co op and we only beat a couple of missions on heroic difficulty. and that is with two people, so basically as long as the second player camps out when the other player dies, that is infinite respawns.

i cannot even comprehend attempting this on your own. it sounds painfully difficult and frustrating. not fun for me, but i seriously respect the skill and dedication it would take.
