Halo 4

Halo 4 Achievements

A Legendary Episode

Completed all chapters in Spartan Ops Episode 1 on Legendary difficulty.

Infinity Multiplayer :: Spartan Ops related. Online Required. Must be obtained on Legendary.
Complete all 5 chapters within Spartan Ops Episode 1 'Infinity' either Solo or Cooperatively.

This cannot be done using matchmaking, those games are set at Heroic difficulty only.

Glitchy: This achievement can be glitchy and won't unlock for some.
The Fix: Complete the missions co-op legendary. If it doesn't unlock then play 1 mission legendary solo and you will unlock it.

CreditMyRifleIsBroken for the fix.

I have just finished doing this achievement. Did all five missions in CO-OP. But for some reason the achievement didn't pop up. Anybody having the same problem?

hello, after the 5 missions in cooperation with legendary difficulty, retry a mission spartan ops solo with Legendary difficulty and there will two achievement unlock
Crimson Alone achievement and A Legendary Episode achievement.

It worked for me.

Really easy you respawn and enemies you already killed stay dead. Did this solo.

Comment #19 by Blade Runner 07
Friday, November 09, 2012 @ 11:35:30 AM

Please confirm.
A person can just do this solo, and respawn an unlimited ammount of times untill all enemies are dead right?
I don't want to attempt spending 2 hours, grinding this cheevo out alone just to find out that either I have a limited number of lives or the cheevo won't unlock due to my deaths.
